LSA Conversion 1st Gen Camaro

Hi all,

Looking some advice, I've tried searching the forum but can't find much, although I'm sure there's plenty out there somewhere.

I've got a 69 Camaro with a fairly fresh 383 stroker with a Carby. It's around 420hp at the motor.

I was looking at converting to EFI for various reasons (might cost around 3k all up)

Then I started to look down the LS route. Engine masters have the LSA for 15k (430kw). What's the go in regards to what else is required for fitting and how much additional cost on top of the initial engine purchase? Anything required for legal reasons in VIC? Engineering & EPA etc?

Much appreciated.

Rob

An LSA is based on the LS3. Google LS3 swap into early Camaro and you will find lots of stuff.

Personally I would just stay with the good old 383 and carby.

Holley Sniper will go on there for about $2K. No idea on specific VIC rego rules, but I’d say an engineer will need to be involved if you want to license it legally. In WA now you probably wouldn’t be allowed to do such a swap, engineer or not.

Sounds like a huge amount of expense for not much gain.

Just wondering if it's worth spending the money on the old school 383 that's not going to make much more power than what it has already.

Whereas the LSA is already much more with plenty of potential. Depending on the costs and headaches etc.

I've only got the original t350. I've also recently put in a 3500rpm stall.

420 HP at the engine is plenty.

I reckon the LSA swap will run you well over $20k all up. You will need a new trans and lots of other bits and pieces.

Worth doing if your budget extends that far and you want to keep the car.

Look up stealth 69 on here. He’s put/putting one in his or check out this thread. Not sure a lot of the old people are still here or on much anymore.

So what trans do you want to run, then I can give you my opinion. What diff and gears. It is a combination thing

Yes I have LS engines in my 2 Camaros, and I have learnt along the way

It is much simpler these days. Do you need an LSA (556hp) or would a LS3 (480/530hp) do? The LSA with a little fiddle will go nearly 700hp. 600hp in a street car is ample, it is about drivability.

Are you sure Roger? I'm still dreaming of supercharging mine (come on Lotto) as I'm not sure 600Hp IS more than enough for the street

Wife doesn't know it Frank, but I did a head gasket in it about 3 weeks ago. Ingested over 5 Litres of coolant into the block. I could just fix it in the shed, but I'm thinking yank it and supercharge it. It was just a dropped in crate anyway, so could be time to build it....I don't have the dollars and I promised her / set money aside so she can invest in her business....but......priorities ????

Of course anyone can have as much as you want, but I think you can have plenty of fun with 600hp in a first gen. I'm sure you understand my thinking.

Just after 600hp it all takes on additional resources.
600 hp diff $2,500, 1,000 hp diff $4,500
600hp trans $3,500 - $4,000 1000 hp trans $10,000 plus
600hp can work with small mods to rear suspension, 1000hp probably needs a back half
Then now you have 1000 hp hooking up, probably puts a lot of twisting on body with serious reinforcing

Also LSA v LS3. Some additional issues with LSA, plumbing and front drives come to mind. Probably going to have to clearance tunnel for trans behind LSA. Bonnet clearance.

One of these

gives, engine, trans, ECU & Engine wiring

Then need mounts, oil pan, exhaust, fuel system & radiator
https://www.holley.com/products/ls_p...ap_components/

I like the Holley mounts, oil pan, cross member & exhaust as they work together

Also the Holley mid mount accessory drive, gives nice tight fit
https://www.holley.com/products/acce...s/parts/20-185

This tank is a really nice piece at a decent price, with range of pumps to suit purpose.
https://rickstanks.com/product/restomod/

Lots of options for radiators

Chris, keep your wife happy ... unless you have separate bank accounts and you don't have an iPhone with location services etc. so she can check up on you. Then you are good to go.

Roger is the voice of reason. I actually think 400hp in a pony car is plenty.
