Largest engine allowed in a 68 ?

[PSIWOG]

Havent been able to find a thread to answer this question so sorry if its been done. Im wondering whats the biggest engine I can fit in the 68 is ? I know 427 (454 block) came standard. I rang a couple engineeres and some werent interested in talking about imports. 1 guy sounded pretty good but wouldnt talk unless I made a appointment, but at $140 an hour Im not paying that just to find out ! The car will be registered and engineered.
SORRY JUST REALISED THIS SHOULD BE IN TECHNICAL DISCUSSION, PLEASE MOVE THREAD.

[EAT-30T]

Do what ever you want basically.... that is all! Chris has a 632ci going in his.... you can keep going up if you want?

[J.J.]

i'd get it registered with a stock engine, say a 350, then once on the road go as big as you want, just inform RTA that you've changed engine once rego'd.

[PSIWOG]

Kurt is that legal mate ? I can just get it registered stock and change it, but would like to know how big you can go without fear of the cops. Do you need to strrengthen body for 632 ? bloody hell imagine the torque :p I have a TV-71 turbo that I really want to use, would fit a 454 perfect, but the idea of a 600 + is just soooooo cool :D

[J.J.]

a cop wouldn't know the diff betweem a 540 or a 632 IMO, some may, 99% wouldnt

[EAT-30T]

only time I know of complications is say if doing an LSx series engine for instance... You can get carby kits for em but the fact you have a polution engine # wont legally allow you to use that carby kit...as it came with EFI... but say you use an aftermarket engine block ie world products.... do as you please! That is what an engineer here told me.... I was thinkin of putting an LS eninge in however with a carb... but a bit too much work for rego etc... and Don't want the hassles of EFI... not in this car anyway..

PS go an 800+ CI motor FTW :) LOL

[cluxford]

OK..see here is what I can tell you.

Legally you can only run the largest block they came out of the factory with, as such that is 396 BBC

However no engineer nor police-person (PC !) can tell the difference between a 396 and any other BBC (albeit mine is a tall deck so is a tad bigger).

Whilst mine has a 632 cuber in it...it will be registered as a BBC (ie 396 block).

No engineer will engineer a 632 cube in a 68...but they don't need to know the cubes.

Oh and yeah 632 = 816 ft Lbs of torque...and yeah I have a new front end, new rear end and sub frame connectors welded in...but as many have told me it will smoke tyres long long before it twists the chassis

Oh yeah!!!! :D 800 cubes. What a mountain. Awesome...

Actually, when I spoke to RTA re the LSX, they said I only had to comply with the clean air regs that applied when the car was built....so a carb should be ok.

Getting it registered with the 350 then swapping is a good idea. Depending on regs in Vic you may need to get it inspected i.e. engine number change. Considering 68's came with 396's any day of the week, and I have seen it published that there were 427's.....and as Mr Luxford and JJ note....632 looks the same from the outside..... :D and is very similar on the inside....save 200 freakin cubes!!! ha ha :cool:

[PSIWOG]

Actually, when I spoke to RTA re the LSX, they said I only had to comply with the clean air regs that applied when the car was built....so a carb should be ok.

This is similar to what EPA told me. I asked what emissions an engine had to pass by if I put any other engine in the car and the answer was ... none. I can put any engine in it and it dosent have to pass EPA.

[blackoutsteve]

Cluxford is right. The engine is only as big as you say it is.. ;)

If you were going to be stupid and tell them you had a 572 or whatever, they may insist on cages, harness', huge brakes, and a load of other crap you don't want/need to do.

[69coupe]

427 is legal. COPO where factory made. Very limited but Factory !
Put 427 on the rocker covers and who would know ?

Definately on 69's. I have one reference to a factory 427 68. If you have more 69Coupe, please point me to them.

[SirGeo]

67's had the Yenko wich were dealer optioned 427.. i would have thought 68's where the same..

[RSZ28]

Steve, I hope they are. On 67's and 68's, the information seems to lead to dealer fitted 427's but not factory fitted. Hoping I am wrong...:)

[SirGeo]

dealer fitted from what I understand should be fine aswell.. The 427 came out of the same era vette's so the "factory" would have had to be involved with it.

I'm just going on what I know with VL's.. I remmber getting a few hassles from some police in regards to my body kit (Director) Front and rear wheels were semi covered, but as soon as I russled up proof it was a dealer (HDT) option I was always left alone..

Anyway all you have to be able to do is argue the point well enough.. Remeber you don't have to be right.. you just have to prove that they might be wrong... ;)

[69camaro]

Steve, I hope they are. On 67's and 68's, the information seems to lead to dealer fitted 427's but not factory fitted. Hoping I am wrong...:)

From the info I've read, 427's were factory COPO options in 69 only. They were a dealer option in 67 - 68 but not factory unfortunately.

[PSIWOG]

Correct .. official word from the mag Chevy rumble :p
"For an extra $489.75, a few fortunate 69 camaro owners were able to factory-equip their cars with the potent 425hp 427cid engines' This was classed as the 9561 option.
Guess you just need to convince the cops its a 69 :D or just buy myself a 69 instead.

[69camaro]

Another viewpoint to this question is TAC insurance which in Vic atleast is covered by part of you registration fee. Something someone pointed out to me recently about another project i'm currently working on is that having a modified vehicle that exceeds reg limits that's not engineered basically voids your TAC cover. I hadn't even thought of it but if you have an accident and someone is seriously injured or worse.... TAC won't cover any of the costs if it's found that your car is illegally or fraudulently registered.
Again this comes back to ifs buts and maybes. If your car is registered as a 69 396 but is actually a 454 no authorities are probably ever going to pick it. But if the paper work says you've got a bog stock base model 307 and they are standing there staring at something like Chris's 632 with twin 850 carbs perched on top..... might have problems. (not suggesting this is what you're doing Chris, just an example).

[PSIWOG]

But saying that, it that the same as somone crashing a VN V8 with a home made turbo conversion put on ? It needs engineers + EPA testing. You wouldnt imagine they would push it that far..... would they ?

Yeah I agree, as I said there's plenty of ifs buts and maybes.... My main point was its not always as simple as getting it registered as a stocker and then doing whatever you want when you have plates.

[PSIWOG]

Ohh sorry to add to my last post there were only ever 69 427's put into the 69 Camaro ....

but if you had 350 or 302 or whatever on the rocker covers, how would the boys in blue know any different?

[69camaro]

but if you had 350 or 302 or whatever on the rocker covers, how would the boys in blue know any different?

9 times out of 10 they probably wouldn't.... But as per the my original post, if the coroner is involved his investigation will see through the 350 stickers pretty quick.

Not suggesting you shouldn't drop a bigger motor in because of this, just highlighting an interesting point of view that I hadn't thought of.

mmmm...yes...HDT....good example.....&....90% confidence....10% fact can work magic....and 40 year old facts are hard to come by....

I remember a defect many years ago for noise.....went straight to the police inspection depot without making any changes....defect lifted...full noise test in echo prone area....no one can know all the facts...

Is the voided cover autmomatic and far reaching? Does it need to be proven that the accident may have been caused by the flaw in the rego compliance?

Ultimately becomes an interesting legal case...to avoid....

But saying that, it that the same as somone crashing a VN V8 with a home made turbo conversion put on ? It needs engineers + EPA testing. You wouldnt imagine they would push it that far..... would they ?

Good point...this is why I got out of the turbo business when ADR27/A hit the streets.

[69coupe]

Ohh sorry to add to my last post there were only ever 69 427's put into the 69 Camaro ....

That was only for the ZL1, what about the other iron 427, and Alum head combos ordered thru the COPO system

[PSIWOG]

Not sure mate .. I was just writing what was written in the chevy mag. I would like to think there are more 427's out there that came standard. Ill do some investigating and come back to you :)

[PSIWOG]

Acording to this statement the 427 was available in 67 through Don Yenko, a chevy dealer ..... Doesnt say how many were actually put in the Camaro through 67-69 though....

http://www.popularmechanics.com/automotive/reader_rides/1271746.html

Enter Don Yenko, noted Corvette road racer and Chevy dealer in Cannonsburg, Pennsylvania. He began retrofitting Camaros with the direct-swap Chevy L72 427 motor factory-rated at 425 horsepower (optional on full-size Chevys and Corvettes) and selling them at his dealership as Yenko 427 Camaros. Yenko started with L78-equipped cars from the factory so that all the components were already heavy duty, then merely dropped the L72 motor onto the original motor mounts. Everything was dimensionally identical. There were 54 built in '67, and he continued into '68 with 64 more.

9560 = Alloy motor - I think there was 69 of these made

[cluxford]

Spoke to an engineer yesterday about my car (coming to take first look next week). Said I had a big block in it but was looking to go really big, how big could I go. He said what 454 or 502...I said nah thinking much bigger than that....

He response surprised me.....

Well to go any bigger than that we will need to see some serious body strengthening and possibly rollbars, but where the real issue comes in is CO2 emissions, large motors tend to fail this test if they are running a big cam.....

So in summary...he didn't say no, but I suspect it ain't easy.

Will keep you all posted on his visit next week

That is surprising. CO2 is different for all motors depending on size, and have never heard of any CO2 limits on early cars. Maybe there is some max limit published somewhere. Am sure a smallish cam would assist in curing this if he is right, and you would still have plenty of horses.:D

[PSIWOG]

This is interesting as I was told it made no difference on engine...... Can you buy a 632 in any production car or is it crate only ? If so what gear box pattern do they come with ?

[blackoutsteve]

CO2 emissions.. Like a 68 Camaro has to comply! If it has a working PCV as per OE, it's legal.

Seriously, don't go there telling them the engine size.
Engineers are not interested in safety features for you, they are interested in you well-over-engineering the car so they're not liable for anything when you crash your car and their signature is on the certificate.

They'll insist on a full chassis, roll cage, inertia-reel lap-sash seat belts in all four positions (unless they insist on front harness' with the permanent removal of the rear seat), over-sized oversized brakes etc.. Mostly unnecessary crap

I had an "engineer" look at my car once and he said he didn't like the idea of a big block in it..
He wanted bigger brakes and a cage etc, but when he was told that big blocks were factory options in Camaros, he said all was OK.
What does that tell you?
It tells me he didn't know what the hell he was talking about in regards to a given engine size and it's relevant safety requirements.

Another example of engineers' BS is this...
Put a BB in a HQ. An engineer will tell you to fit bigger brakes, yet..
Put a HQ brakes on a BB Camaro and the engineer with tell you it's OK.

Seriously.. shut up regarding the engine size. :)
"It's a 454 sir".

:D that's really funny :D ..... supporting the notion that this is all about opinion...just need to find someone whose opinion aligns with yours....

Interesting thing about a HQ is that it is probably a better candidate strength wise than a G1 camaro. Certainly an engineers opinion of HQ brakes on a Camaro talk to that.

Then again, an engineer does put their ballls on the line :eek: when they sign off, so they will overengineer if they are not a subject matter expert on the particular car.

Considering GM ships 502's in trucks, 632 is a mere 20 and a bit % over that. Not much....:)

[RSZ28]

This is interesting as I was told it made no difference on engine...... Can you buy a 632 in any production car or is it crate only ? If so what gear box pattern do they come with ?

Someone may correct me, but I think that 455 or so was the largest production car engine ever shipped in the US, at least with GM.

If you mean the bolt pattern...gbox to engine...normal GM small block/big block pattern. The same rat sized blig block supports 396 and up. Up to 502 from GM, the cubes beyond that come from the aftermarket. I recall maybe there are 800 cube aftermarket big block plants :eek: , but not sure.

[cluxford]

Yeah...

It's running a 427 crate motor......std in 68.

But look what I have done to make it even safer...330mm discs all round, c5 Vette coilovers, power steering, hydro-boost braking, 4 link rear, sub frame connectors...etc....

Should be fine....

[PSIWOG]

hydro-boost braking

Umm without sounding stupid whats hydro-boost brakes ? Obviously there is vacume booster but hydro ?

[cluxford]

Hydro-boost braking gets it's boost from the power steering pump as opposed to the engine vacuum.

Normally engine assisted brakes have a PSI of around 4-8,000 PSI. Hydro boost ones can go as high as 20,000 PSI.....

only problem is the engine stops turning you have no power assisted brakes at all.....it's all down to you and your foot

[PSIWOG]

Ahh ok .. thanks :D do you have any pics of the setup im interested to see what it looks like.

[blackoutsteve]

Normally engine assisted brakes have a PSI of around 4-8,000 PSI. Hydro boost ones can go as high as 20,000 PSI

Are you sure the pressures are that high?
I had always learnt that brake line pressures rarely exceed 2000psi.

[PSIWOG]

I had always learnt that brake line pressures rarely exceed 2000psi.

I think he means the pressure from the p/s assists the brakes not actually increasses the pressure to 4000psi.

[cluxford]

yeah sorry....it's not 4,000 I was working off the top of my head and had other numbers in mind...I'm not even sure I have the Hydro-boost numbers right but I know they are over 10,000

[BMF1968]

My car runs a registered 632ci. all completely legal. It's all engineered and had to undergo track testing, (brakeing, lane change ect.), to satisfy the engineer that the car could handle it but he was happy and i got my reg, complete with 632 on the papers. The only thing i didnt offer was overall horsepower capacity, and since they didnt ask, i didnt tell, Dont know how keen they'd be on putting 800+ hp on the street.

[blackoutsteve]

I still think it's funny that they (think they) need to test braking and lane changing because of an increase in engine capacity.

Do they know that the weight and external dimensions of the 632 are practically identical to a stock 396 except for a 0.400" taller deck height?

I mean it's not like the CG of the vehicle was altered or, braking or lane-changing is tested at WOT. It would have been from or at a speed that any clapped-out 6 cylinder was capable of, right?
How can more cubes effect those results? What were they looking for beyond a stock 1968 Camaro's performance?

Theres a couple of other guys available here in SA but i hear conflicting reports about there services and can't say ive seen any cars they've got through personaly... but you hear stories. When i spoke with inspector at regency park (SA RTA inspect station) he told me that all they were really looking for is someone else's name on the signoff. They just want someone to point the finger at if things go wrong.

That guy is gold. Is the engineering and certification expensive? is the rule in SA that the emissions situation is based on the year of the car?

[BMF1968]

All up under 4 grand which includes $500. hire of testing facility for the day.
i belive you are correct in assuming that emissions only relate to the cars manufacture year, but this only holds when you are building your car to within the original manufactuers spec's. Alot of the previous anwsers relate to this, where motors can be no bigger than was what was available in that model for that year. To go this way really doesn't require engineering cause your not stepping outside the original guidelines. When you build a vechile extensively modified enough to require full certifacation your actually building a new car (even though it's wrapped in a 60's shell) and therefore must comply with currant emission requirements that any new car company has to comply with. I was told that there is something like only 6 requirements that a new car builder MUST adhere to... Minimum height from ground to any part of car(exhaust, sill, suspension component) is 90mm, Maximum decibal rating is i think 96 decibals, there are minimum lighting requirements(headlights, indicators ect.), a minumum line of sight regulation(might apply to something like a rod with a chop top or car with motor/blower protruding through bonnet) that sight cant be impeded to see signs, stoplights ect and the emission laws. Theres a couple more and i understand there genrally considered Australian Standards so they shouldn't vary from state to state but obviously i'm no expert and i suppose any decent engineer could fill you in. You can also approach someone at your RTA but ask for someone in the technical dept. cause most of the mongs working the front desk dont know jack. As long as you build your car to fit within these rulings the rest is open to your engineer.

Thanks BMF ( is that Big Mo Fo engine ?) :)

Yeah RTA tech here is quite good. They have all the docs avail somewhere on their website with a list of recognised engineers.

They do roadworthies here every year, so are pretty close to every car over 3 years old.

Does that 4k + 500 included emissions testing? To current standards?

The emissions rule came in something like Jan 1 this year. Any "new" car or considered to be new vs modified, had to have current emissions. Know some guys with Cobra kit cars that needed to put late model Gen IV Holden motors in to get them reg'd.

cheerz.

The 4grand did include the emission testing but if the regs have changed this year i'm not sure.(did my compliancing almost 12 mth's ago) but is something i'm gonna follow up on. Best bet is to speak to an engineer localy, but ask around and get one who GETS cars cause i saw several before the guy i eventualy went with and most of them look at you like "why would you want to do that?" A good spot to start would be with shop's that do chassis mod's cause they will probably know most of them in your state and dealing with them all the time will be able to fill you in on which one's worked out best for previous clients. One excellent way to get mod's passed is if a precedent has been set and attained rego. These will be the guys who'll be up on this sort of stuff.
Hope this helps, I wish i had a outlet for info like this forum provides when i first started planning my ride. It would have saved me heaps of phone calls, foot slogging and wadeing through useless information guys would give me from a mate who knows a mate who knows a guy who once...

I wish we could do the same in Queensland but they seem to be very strict and most engineers (all bar one who wanted to do all the work in his own shop) don't want to talk about mini tubs big motors and aftermarket front clips. Unfortunatly I think telling them it is a 396 and nothing else is the only way regardless of what you do.The 4grand did include the emission testing but if the regs have changed this year i'm not sure.(did my compliancing almost 12 mth's ago) but is something i'm gonna follow up on.
