I have a 1972 LeMans Sport Convertible with the buckets, console, T41 option, 350 2bbl, TH350. I put in a 455 and didn't change a thing with the motor mounts, just got new ones. I did change to a 4-core radiator. I run RA manifolds with a custom bent 2.5" exhaust and Dynomax super turbo mufflers. I just have to replace the original open 2.78 rear with a 3.55 posi since I burnt off the right rear tire. Motor is a 0.030" 455, 7K3 heads with RAIV cam/Rhodes lifters, HO intake and Q-jet. More than enough power for a daily driver.
