I dunno, those 55 cubes make a big difference. Not that a 400 won't run, but for raw power the 455 seems the easy winner. I say that not for what rolled off the assembly line in 1970, but what I have done at the track.
A bare stock 455 with some 350 6X heads and a medium cam, will propel most led sleds to a 12 second time. The 70 455 had a point of compression on the 6X head set up, that is just more horsepower. |
