Pushrod Length question I'm fixing to put a cam in my truck, swapping actually. I'm going with a 224/227. My question is, do I need to use a different size pushrod than stock? I know I need hardened ones, but what length should I get? Thanks for the help.

The lift of the cam has nothing to do with it,
the base cir of the cam, the installed height of rockers (aftermarket)
and if you mill the heads, are reasons to change lenth of the PRs

When you think of adding lift to the cam, the extra lobe height isn't added to the top of the lobe, but rather cut away from the center. Kinda like making a tree taller by digging out the dirt from around the base.
