Pistons and cam on the way.
Did a bunch of math and typing into Desktop Dyno and settled on a cam that will keep the BMEP happy (similar to stock but carry it past 2000 RPM) and make power past 4500 RPM if desired all while losing nothing down low. I also have to keep the torque at bay since the 5-speed input torque rating is already being pushed by the stock 460.
I had to be picky with cam selection as this is a 10.5:1 engine and going "too small" or stock on a cam would really keep my dynamic compression in that 8.9-9.1 range and that's too much for pump gas.
Anyhoo, once the pistons show up it's off to the machine shop and balancer.
