Pat,
Mike is right on the money about the advice he told you. One thing I can add is on the cam grind. On a hyd. roller, you dont have to go as big in duration to achieve the same results as a flat tappet cam.
I would run, in your application, about 280-284 advertised duration, straight across. With a Cobra, with the 2" header primary size, you really dont need the extra exhaust duration. Especially if you run the Edelbrock heads. They have a very good exhaust port design!!
Anyways, 280-284 Adv. dur. 232-234 .050 dur on 112 lobe sep.
108 intake centerline! Remember, seperation is different than centerline!!
This cam will give you unreal torque from 2000 to 5500 and great power up to 6200.
Hope this helps!!!!
Tom
