Hey guys

how do i find out the proper pushrod length? i have a set of 5.3 heads and i having them milled to a 58cc chamber and i will be running a t-rex cam with 610 intake/612 exhaust. so what pushrod length do i use i figured not the standard 7.4's but then there is the 7.35's, 7.1's, and 7.15's. i am trying to order pushrods and the rest of my motor this week and i was hoping someone out there could let me know how to calculate the necessary length for my pushrods. oh yeah stock rockers 1.7 if that matters.

thanks

 

Summit, Jegs and several of the sponsors cary a tool to check the PR length. I would start there.

 

The only real way to do it is just as Steve suggested. Get an adjustable pushrod and figure it out.
