Performer RPM Air gap vs. Z28 intake
Is there any one out there who can give me an educated guess on the power difference between a performer RPM Air Gap intake and a stock aluminum 69 Z28 intake? The motor is a 350 with 186 cast iron heads 2.02/1.55 valves, 10 to 1 CR., crane roller rockers, comp. cams magnum 292 dur. 501/501 lift., .244 degrees , holley 650 dp, full MSD ignition (dizzy, 6 AL box, super conductor 8.5mm wires), and Hooker super comp 1 3/4 '' headers running into dual 2 1/2'' pipes with Dinomax super turbo mufflers. I am running the Air gap now, and would like to know what I would be sacrificing in the way of horse power and torque if I put the stock Z intake back on. Also if any one has a desk top dyno handy, I am curious what my horse power and torque numbers for this motor would be.
