So i got my 440 dynoed, its a fairley stock build, 915's port and polished, stock bore, holley intake, headers, dui ignition, 750 holley, 3:55's sure grip, 2500 stall. Engine put out 387hp 420ft lbs torque. The cam is my question. I used a Comp 280H Magnum. I'm wondering if ii should have went with a Extreme energy with a little more lift. I really wanted to break 400hp at least. Any suggestions?
