For motor mounts, ive tried almost every setup. The spohn ones work the best.

S&P style ones will cause you nothin but headaches.

Re: Another LS1 into a 3rdgen.

Alright, Got that on the list.

Im Not much of an Electrical guy... I can do it. but takes me some time. I dont care about what wires Specifically.. just a few would give me an ideal.. I have access to alldata.. and I can get some Wiring digrams while Im here. but once i get home and do this swap.. I wont have such access.

The one design that essentially puts the thirdgen mounts on the front of the LS1 mount (i put up pictures of that) positions the motor too far forward.

Im just finishing up a 2nd set of mounts that are teh same idea but push the motor back 1". Ill hopefully finish them for tonight and get some pictures up of how it mounts before i end up just using my straps & plates i made.

BTW: If anyone need's mounts fabricated, ive got 1 set of 6061 Aluminum S&P style, and can also make spohn type mounts.
