I agree with burnin oil. You will need all the info necessary to be able to calculate the dynamic compression. You will also need to know what combustion chamber sizes are available from AFR on those heads. I'm not an expert, but I believe the AFR heads' flow ratio between intake and exhaust is so good that a split pattern cam is not necessary. If the dynamic compression is too high with the Howards 180885-10 cam, you will have to go with a cam that has a later intake closing to bleed off some cylinder pressure. This is often a more radical cam such as the 180265-10, but cams designed specifically for N2O or boost, will have a later intake closing and bleed off cylinder pressure without having a higher operating range.

what ever pistons come with the short block, and I have a 2200 RPM stall now and a built 350TH, which is fine with the howards 180885-10 cam , and I already run premium 91 with my current engine now(per Manufaucture)
