BlueOvalRalph, Nhra has a devise they put your push rod and your lifter in to find correct length of your set up,then they put their lifter and your push rod in to get same length, they use a adjustable lifter, then they use this set up to check lift,. Tom

I was told NHRA would not use any lifter I was going to provide, they would use their own.

I don`t how "oddball" a 5.0 Mustang Stocker is, but I`ve torn down 3 times here in Div.6, and the certification team never had a "solid" Ford hyd. roller lifter in their kit. The first time, I ended up having to disassemble on of my own lifters,& "plug" it. After that, I just kept a plugged lifter of my own in my tool box, and on 1 ocassion, the cert .team borrowed my checking lifter.

Re: Stock Valve Lift

I suppose I shouldn't be surprised that they don't have a lifter for that. They certainly should. Shoot, I have one that I use to check piston to valve clearance.

Re: Stock Valve Lift

The check lifter they use it made by Clark Holroyd. He will sell one to you.
