I've been wondering about the emphasis placed upon pushrod lenth. I've only built a dozen or so engines, some mild some wild, but any engine I've built running hydraulic lifters I've used standard pushrods.
My 4.7 build will be zero decked, so ~0.021" milled (yeah?), surely the lifters will accomodate that?
