I have a ZZZ crate motor. I installed a comp 268 cam and afr 180cc heads with lunati 1.6 rockers. I went to the tighten everything down at the shop and the guys told me that I need longer pushrods for this setup. I want to know what standard hydraulic roller pushrod length is. They were recommending 7.400" rods. Any input would be greatly appreciated.

I used to know some of the stock info off the top of my head, but it really isn't correct for what you have...sooo, just spend the 10 bucks (or make one) for an adjustable push rod absd check the pattern on the rocker...measure the adjustable PR, and order a set...depending on your cam...you might have to do one exhaust and one intake, and maybe have a set of 8 each.

 

Yeah I am not very familiar with this stuff, I guess I will have to do some more research. Thanks for the info
