I'm looking for info on swapping a caddy 500 into my truck. Specifically...is there anyone who makes bolt in motor mounts for a 73-87 truck? Also, can I use 454 TBI parts to turn it into an EFI motor? I don't think it'll eat THAT much fuel and It'll stay stock or close to it for a while since I'm most likely going to be using an NP205 now and this is gonna cost me quite a bit to do the whole swap. I scored a caddy 500 with a matching TH400 for $200 today. It supposedly runs but has a bad coil. Even if it needs some work, $200 for the combo is a damn good deal in my eyes. Also, Branndon, if you read this, you're going to have a PM shortly.
