I have a 383 crate shortblock that has been decked and squared up. With afr 195 street eliminator heads. Based on part numbers used it's safe to say the block has had about. 020 removed from the original deck height. An erson hydraulic roller cam and Elgin 1.6 steel roller rockers.

Obviously I will have to check pushrod length. My question is with so many length ranges available for adjustable pushrod which do I get? From 6.5 to 7.5" ? I am hoping I do not have to buy multiple checkers. I would rather spend 20 dollars vs 80 for a complete set.

 

This is the one I have. https://www.summitracing.com/parts/cca-7702-1/overview/ Covers the range you need.

 

Almost ordered the wrong one. Failed to consider factory roller cam setups are quite a bit shorter than standard flat tappet setups.
