Well, I am torn between this 455 because it is a great offer...and a 440 (you know the 400/428 crank combo) that I originally wanted and have someone holding onto a 400 block for me. Anyways....I don't really plan on racing it. I mean, it might make to the track a few times...but I definitely want to to launch pretty well. Trying to build one of those cars that is good at everything (1/4, handling, highway chase scenes with Texas state troopers in the dust hahaha), but probably not GREAT at just one thing.
