Review on 🔍 Accurate Proform 66789 Push Rod Length Checker for 3/8" Studs: Enhance Engine Performance by Moe Gilbert

After getting this I realized I can't get accurate measurements with hydraulic jacks on a newly built one that's sitting on the bench. I bought a one piece lifter from Comp but the push rod seat depth was different. Still does not work. So I found that this tool measures the hydraulic stroke about halfway and then subtracts about 0.30 for the preload. As a result I got 0.100/2=0.50-0.30=0.20. Close enough for standard length pushrods. Is it ideal, no. But I don't use roller seesaws either.
