Re: 6.2 vortec ???????
Cams run around 375.00 .you will want to do springs as well usually around 150.00.add long tubes.the cams worth at least 50 crank hp with the headers adding another 25-30. Plus a tune you should be able to make 500 crank hp.ive seen it.my 5.3 will make 425 with cam ,ported heads and carb conversion stock bottom end.
