Re: 1970 nova ss

Does anyone have any credible dyno info on what a stock '69 L78 makes versus a stock '70 L78? Someone once told me the 163 intake was good for 10-15hp over the pancake intake. But then again, the '70 would actually be a .030 overbore in stock form for 402 CID.

Seems like 10-15hp might be a stretch, but I gotta believe the 163 intake is better.
