Yep, I purposely left the heavy hitters out. (thinking more fun street engines here) I bet that 375 horse was a nasty Mo Fo. 2.02 double humpers and a big "full race" solid lifter cam. :lol: Then think about the mild combination Hot Rod put together for their 400 horse 318 build. No comparison how easy 400 horse is to get out of a Teen. Better cam technology now days though.
I bet if spec'd out a 318 with similar cam cr intake carb, would put near the same power with stock heads, I think 318 would come up a little short with no head mods but add a set of X heads bet it smoke the 327.
