Why are 318's low HP and torque?

And if turd 302/5.0 is good the 318 is 16 cibes bigger with better flowing heads than any stock turd head.even the factory gt-40 heads.:prayer:

Also 318's are dirt cheap if not free:cheers:

I got one 318 for $10, and another for free. They are out there. Now if I can just find a 383 in as good condition for $10 I'd be happy. :lol:
