Guess my Hp and Tq

OldmanRick Cam rpm is 3500 to 7200 Intake is 3500 to 8500. I will buy the TTi 1 7/8 headers next year just cant swallow the 900.00 after spending almost 12000.00 on this build. It will be on the dyno in 2 weeks. If it don't make real close to 600hp I will sell it and start over.
