I've come across a wrecked but complete '71 Coupe deVille with a 500" engine and TH400 tranny. I'm looking to put this in my son's '46 Chevy 1/2 ton. The Caddy engine, BTW, is only 10 pounds heavier that a SBC, 100" bigger than the biggest SBC built, and gets a heckuva lot more attention at a cruise or a show!. I've even thought about a 440 Chrysler with a Six-Pac (Tri-Power for those solely of GM upbringing!), as I have three 440 engines along with a Six-Pac set-up that's about 75% complete. People don't hesitate to put a SBC in just about everything; I think it's time the tables were turned! :p
