Installing Caddy racing lifters, what is their preload?? Im doing a cam install and am installing the following components;
Custom Grind Cam(spec'd by PatrickG)
7.425" TSP pushrods(recommended by PatrickG)
CTSV-R Lifters
Stock 1.7 rockers
Anyways, what is the recommended lifter preload for the CTSV-R lifters? Is it the typical .080" or less or more?

Mine took about 1 1/4 turns from zero lash to 22lb/ft. That works out to about .050". I would have preferred 1 turn or .040 but I didn't want to shim or buy new push rods and mess with my wipe.

There is some sewing machine noise since my cam has an aggressive ramp and over .600 lift.However I think it's muted some by the iron block, plus my exhaust is quite loud.
You really don't need a dial indicator' because 1 full turn is .040". I torque in 1/4 turn increments. You start a zero lah, which is the point where the push rod won't turn freely in your fingers. then start counting the 1/4 turns till you get to 22lbft of torque. If you go over 1 1/2 turns go to a shorter PR.

Yeah but you can get your preload amount by turns of the rocker arm. I had around .050" at 22 ft lbs. I tried both ways(dial indicator and turn method).
