What point are new pushrods needed?
Planning to run 10psi intercooled with new forged 355 LT1 motor. i was using the stock 94 harden pushrods with stock cam,1.6rr and comp springs with 7-8psi. i'm going to run a hotcam and not sure what type of springs as i want to sell the comp ex 612 springs. do i need to upgrade my pushrods?
