    Mine is a long ways from running but the hard part is done. The engine casting is completly different in many ways but the important ones are the engine mount ears (GM flat mount to block) that are about 5" forward of the GM mount position. Also the driver side cylinder sits back and the passenger side is forward which will cause a little interference at the fire wall. Also they used at least 3 different oil pans and you want the rear sump pan to clear the crossmember. I have pictures of the mounts that I made for mine posted on the new photo gallery. Look for "45acp" and you will find the pictures.

    For starters I'd try to find a running rear wheel drive 500 caddy as the donor. You'll need the engine mounts and BOP TH400 tranny. I thought the swap was pretty easy although my foundation was a tired K30 with a 454 th400 np205. It may be more difficult if you are starting from scratch with a different drivetrain.

    Look up Maximum Torque Specialties on the 'net. An excellent site for Cadillac performance and swap stuff. Even shows a Chevy 4x4 truck with a Cad motor swapped in. The site claims that the 500ci Caddy will blow away a 454ci Chevy setup...Anyway, its a good site with a lot of information.

    For less HP the 500 caddy will out muscle a 454. The only downside is the disparity in aftermarket preformance parts. If you want cheap torque, a stock 500ci is hard to beat.
