318 broke into the 11's

66, I use Edelbrocks a bit...lol. I like them. But like anything else, if you dont look for probelms, you wont find any until they find you. I'd use edelbrocsk over X heads every time if I could convince guys to spend the money. Redoing wiped out 40 yr old heads costs within $2-300 of them, and they can outflow Xs by a long shot, especially on the exh side.

Duster, see, I knew there was a reason..lol. Just for gigles, you might want to experiment swapping that Edelbrock back on it...
