Re: 472 Caddy or Pontiac 400 swap
ok, friend put a 455 pontiac in his blazer... you need a bellhousing with the BOP pattern and that is a 4x4 tranny (no tail section). so the only tranny that i know of is a 350C... has both bolt patters on it, or you can get an adaptor.... ok, as for the install... put your motor mounts on the motor, both parts, set it in the truck, then weld them in... it should work... as for the exhaust... headers are a PIA (took about 6 hours to get them to fit), you have to bend them to get them to work, so i would stick with the manifolds, tho they do rob you of a lot of power tho... make sure your power steering pump has the same connectors as your steering box... ummmmmm that is all i can think of for now...
personally, if you want it quick and cheap, find a running 350 and it should bolt right in depending on what the truck originally had in it...
