The thought has crossed my mind.

We need to see how the LT1 fits first. The LS engines have the rear face of the cylinder head much closer to the bellhousing face than a traditional Chevy. In some bodies, installing an LS with the bellhousing in the same place as a Chevy means that the LS heads hit the firewall.

So we'll need to get the Chevy installed in order to see how much further forward, if any, the LS would have to sit.

Here's one where you can see the weird angle at which AMC mounted the diff:

I'm still on this. I'm up to Revision 9 on the mount plate on this side. I've been making subtle tweaks that don't show up in photos, but I've finally nailed it. The slots for both drops are in exactly the right places and when the drops are clamped in place as shown above, I can run all four mount bolts in and out with my fingers, so all the important dimensions are NAILED.

The rear drop still needs some work, but I think the next update will get it. The rear drop shown above doesn't meet the mount plate correctly, but does accommodate the 15/32 transfer punch required to locate it correctly on the disco housing. I "fixed" it where it met the mount plate, but then it wouldn't match the hole in the disco housing. I updated it to correct the hole location and got close enough that I can get a 27/64 transfer punch through (barely). That gives me the exact amount I need to move it and a careful photo gets me the direction I need to move it, so I can, if not nail it exactly, get it really really close on the next rev.

I took a stab at a very rough snout bracket for the other side of the engine, and I should be able to get those parts cut this week. However, I will be on Navy duty for the next three weeks, so I won't be able to come back to it until the end of September.

Got to play with the first guess diff snout bracket and drop today.

The snout drop in place. Yes, as shown it interferes with the oil filter. I've fixed that for the follow-up revision.




Some detail on the surgery required on my SWAG dimensions in order to get it to bolt down:




Both brackets in place, along with the transfer punch to mark how they overlap. You can see the chunk I had to take out of the upper one because my eyeball wasn't calibrated well enough when I was using a scale to lay it out in the air.




I updated the CAD with the results of today's test fit.
