Craig; I like the 390's and I'm sure you can get a 460 to stomp it but I've seen some 390's that would really run. I used them in ambulance, but these were all balanced and built to run the long open highways in michigan. we had a lot of problems with the 460's over heating. We found out of all the gas engines we put in to them the 454chevy to be the best or the least problem, We should have tryed the 1970 500 caddy engine. HE!HE!
