Performance Questions 225 vs. 360

I always want to build a early a body dead stock looking granny car /6 car sleeper, I don't want to talk you out of doing up your /6 which I think is Kool I want to build a 400+hp 273 a magnum engine would make more sense for both of us but sometimes it more fun to do things the hard way Post #36 is 225 I've put through my dyno program.
