Ok this is my first post so hope this works. I have a 408 striker that I recently built but the motor seems to fall on its face at 4900 to 5000 and I don’t want to rev past that it has a carter 600 afb carb with an edlebrock LD340 intake and stock 360 smog heads with comp pro comp rocker arms with a .480 lift comp can a 2.5 inch exhaust with headman headers. Do any of you guys know what rpm it should fall off at ?
