Those are impressive Keith, for a dual plane, mid numbers cam lift, lobe sep., compression, ect., and not a extreme racing engine. If I could get a pair of Blue Thunder heads for this sponsor build for a great price, I may buy them. I've seen flow bench numbers of over 400. I would prefer them over the Edelbrocks. His intakes are very nice also.
What seat psi are on the springs ?
Like with my last Victor, I had to mill down the carb. surface 1/4"-3/8" for hood clearance. I did not feel a difference though. Do you think 1/2" would be too much and hurting the performance ?
As you both know, that's why the RPM is used by so many Cobra owners.
Barry/Keith-although having fun with high torque at relatively low rpm's, and bragging rights, with the Cobra being so light weight, we can't use much of it anyway. With this new motor, I like the idea of using higher rpm's, to say 6,000-6,500. But, at what point is too much seat pressure and too tall of lift for the street and still be reliable ?
I don't mind lashing the valves or replacing the springs apx. every few years, but I don't want a pain in the @ss,... to radical for the street either. I had enough of that with my Pro-Street Camaro,.... many moons ago.
I hear the T&D valvetrain can withstand the abuse ?
