That's some good first hand information there Iron Angel. I'm reviving my 402 deal again. Those Chevelles and police car 402's must have had a dished piston didn't they? Did the trucks get a bigger dished piston and lower compression? Is it possible to get any decent power with stock truck pistons or is compression way low?

There are plenty of 454's around for not much more money but i really don't need a ton of power for the convertible it is going in. I just need the big block look and sound. If I had to buy pistons for a 402 then I might as well build a 454. I have always wanted a nice 402 though and I'll bet a low compression truck engine would still work good enough for slow cruising and an occasional burn out. Thanks.
