ok all you need to do is change bellhouseings and mounts with your buddy...correct me if i am wrong but dont those parts interchange from 73 to 77? just do a full swap...i love my 460 and would never go back to a 390....but then again i went from a stock 390 (with a 2 bbl) to a mild build 460 with a 4bbl.....still never go back. well maybe to a 428CJ cuz my dads got one of them in a 69 mach 1 and man tha is a good motor!

you people are lame...i am the only one who told him to go for the 460?
