Why are 318's low HP and torque?

Chryslerkid, If you're interested another member posted a set of 302 heads in the clasified section just today. I'm working on a very similar setup, just wish i could find a sure grip for my 8.25 that was affordable... Oh well, gives me something to keep after.


Here's the link on the 302's in the classifieds:
