The LS1 in my 34 has custom brackets to swap accessories around. The idler pulleys mean the brackets don't have to be overly fancy to work.

Hope the pic below gives you a few idea.

Thats one nice rod Surly. Is that a Holden alternator sitting up top? You got the custom brackets made up?

Thanks for the post and shot and welcome on board.

Yes Mr Luxford I hope to get out to WSID a few times once it is all done and sorted . A VE Commodore ran a 12.0 out there a few weeks back with the A6 and MT's and a stock convertor, running a cam, 1 7/8 4 into 1's, and an Oztrack tune. And those things weigh in at about 1850kg's. My 68 was 1520 kg with the BBC. With the LSX it should be in the 1430-1450 range....though am sure the rear end when I get to it will add a little more...

The 6L80/90 is a very different box. Almost no hydraulics compared to the traditional trans. Just an in box computer operating a few solenoids which operate the clutches. Doesn't that sound simple? These A6's are running in a variety of cars & trucks, so getting these to work has become a lot simpler. Still a lot to know about them but its all fun.

This forum helps supply the inspiration to do interesting stuff that aint all that easy....

Unreal..
That's the hope Mr EAT, ....A6 has something like a 4:1 first gear, and about a 0.67:1 6th. With a 2.9 or 3.0 rear, you can pull a hole shot with an equivalent of about 4.11's in the back, and then cruise home at 1200rpm at 100k's. Or something like that. But I would never claim to have done this for the mileage right? Even my missus would see through that.

A ways to go yet....

Cheers all n have a good weekend.

Been busy with other stuff, but there is some more progress....6 speed auto arrived last week and slotted it in for a trial fit up....its a tall piece of work...required tunnel revisions...it hurt to do this...but it was a plane Jane car, no numbers matching, and the A6 is not gonna fit any other way.

Some comparisons shown below re the differences between the 4L60 and the 6L80/90.

Next on the list....trim out and finish the tunnel nice and neat and fab up a new rear X member. Get the steering mounted back in to check what revisions are required on the oil pan....etc

Yes it is a bit of work....but not as bad as the worst case I feared after I saw a 66 GTO on V8TV with absolutely no chance of fitting without major surgery.

It looks like it will take approx 40mm at the front and 20mm at the rear of the box to get good clearance. It would work with zero mods...if it did not have such a deep pan. As it is I will need to take an inch or more out of the pan height to get reasonable ground clearance. It has a truck pan. Deep and lots of fluid capacity. The Commodore and Cadi pans are shallower. Though even they will need to be modded as they are 35mm shorter.

What are projects for right?

Some more shots of getting the rear cross member worked out, trans pan clearance, exhaust manifolds. Yeah I know I should do extractors, but the manifolds...VE Commodore...will save a lot of time now. I hope. Time for some tubes when the body is in the shop for paint....

Don't worry about the manifolds... those cast things are good they won't hold you back much at all!

Looks like you can work some magic with photoshop. Can you work up nice logos and stuff with intregrated piccies as well?

Thought some of you may be interested in what is required to fit an LSX motor into an early Camaro....as far as engine mounts and the oil pan is concerned....

From side with stock F Body oil pan with gap to cross member at front..(LS7 block).

Oil pan clearance over cross member...shows LH engine mount. ATS mount kit bolts on to standard block mounting holes, standard type engine mounts bolt to stock frame stands.

"Short" motor looks quite compact sitting in stock small block position...

Lower down from front with heads on, showing (though photo is not great) VE Commodore exhaust manifolds which fit well...oil pan sits about 15-20mm above front x member.

Right hand engine mount shown bolting to stock frame mount, good pan clearance, and view down main tunnel where the 4" crank will sit. LS7 block features billet 6 bolt main caps, line honed mains, and is deck plate bored and honed from the factory.

Notch out of oil pan to permit steering clearance across range L to R.

From below with steeering on centre...oil pan is a cast unit with integral filter mount. The pan is designed to be a structural element of the engine assembly and is very stiff.

Notch in pan with stock pickup location shown. Pickup needs to be moved to the rear a little to clear the notched pan.

Next step is to get the pan welded and revise the pick up location.

Ian, that looks amazing...interesting activity on the oil pan there. Surprisingly easy when you think of it, show how little the exterior of V8's have changed in 40 years compared to the horsepower per cube they pump out....
