Here is a picture of the retainer measuring tool that I made. I found that retainers from different mfgs had different installed heights. There isn't a spec for retainers so I made a tool with a 10 degree taper that allows me to measure the different retainers.
And I see it with this setup I am fooling with right now Andy. So I set one up at 1.950. Switch to a +.050 lock....614 Comps.
Around 2.00 Right? Noooope. Now we are +.070 setting at 2.020...I can see + or - .005 or so but .020?
Since these are PAC retainers maybe I should try locks from PAC?
Maybe I get a true .050 and gain some rocker clearance I was worried about originally. When I checked it the other night I didn't realize I was getting .070.
