318 broke into the 11's

Yep....and I'm only running 9:1CR on pump premium gas. I really believe a most of it has to due with the converter, cam and nitrous all working together. More so the nitrous and converter being matched. I really believe that if I was running factory casting head I wouldn't be close to those numbers. The edelbrock heads are far better than any of the factory heads......now if they are ported or had any work done to them it's up in the air. I'm sure a worked over set of factory heads can probably match or out flow the Edelbrocks. But stock for OTB heads the eddies win hands down.
