What length pushrods should I be ordering, I have a set of 850-16 comp lifters (non R style), was looking at comp hi-tech .080" 7.400's like I have in the tahoe, but how do I know what length? I'm running an MTI R1 cam, and harland sharp rockers. I'm not assembling the engine, so when it goes in for a machine package/assembly should I let them get the pushrods?

 

Pushrods should be one of the last things bought for an engine. Let your shop calculate what pushrod you need once the top end is together.
