Quote: Alright, I've heard alot of people claim that these heads are too big for sub 416" motors but its all relative to the RPM that your turning. How much RPM would you say would be required with these heads on say a 394" motor. I can understand the too small cid vs. too big of a head on a street motor but what about the guys that dont care about street driving. These heads look pretty killer.
to give you an idea,on a 345 cid engine with the right combo it should be able to reach 9300 rpm.wow!
