Thanks for the replies. Just wanting a few references on what one would like. I’m building a 400 for my Polara and plan on trying to make it look stock or has stock has possible. Will probably make a few changes in appearance etc.... I do have the motor completely apart right now. And now I’m figuring out a plan for a build don’t know if I’m gonna stroke it or just build without stroking. Gonna be a long build either way. But I think it will be cheaper to just build the 400 without stroking it. And I think I can get the 400 to run good without stroking it.
