Pushrod help I have a VERY LOUD valvetrain. I am using the stock pushrods and think it could be the cause. I know I need a length checker but wanted to throw my setup out and get some guesses on length I should order.
Iron 370ci
317 heads stg 2.5 by TEA, milled .010"
224/232 .585/.595 114 lsa
harland sharp rockers and caddy lifters
also this is a procharged car and after 6600rpm seems to fall on its face....

well pushrod length checkers are only like $24 i would definately buy one. There is a very good posibility that they are too short. Too short means not enough lifter preload which means a harder hit on the lifter with the pushrod, less valve opening, and poor top end from low lift. I'd assume it would be like retarding the cam a couple degrees due to the delay in pushrod action.
