I finally got around to putting in the 454 today, wasn't as bad as I thought it was going to be. Had to move all the engine and transfer/transmission mounts forward one inch. Of course drilling 36 holes is not a whole lot of fun, but it had to be done. Also had to cut the firewall on the drivers side to clear the valve covers, just about a half an inch. The engine I used for setting everything is still in need of an overhaul, Smokes like hell. Think I'll run a set of Hooker shorty competition headers, looks like they will be the least trouble to plumb up. Anyways here's some pics.
