I think I have been thru this once before. Seeing how the Pontiac 350 and 400 were separated by 20 HP according to some factory ratings I can see how "you" would argue that. Consider the 350 had a 3.88 bore vs. the 400's 4.12 bore both having the same stroke of 3.75. Which one do you think will have better breathing abilities? I plan on snatching up a 350 Pontiac this summer for a T build but... if I cant find one and a 400 thru 455 is available then I guess I will have to be satisfied with that.
