LT1 Stocker Valve Adjustment-Short Travel Lifter

[Tom Turner]

Rusty;
On initial setup, I use an .010 feeler guage under the rocker tip and bottom the lifter button (collapsed ) just as if it were a solid lifter. This puts the button roughly in the middle of the travel. After a few runs I quickly look for loose rockers (or tight) and then go back and adjust to zero lash, medium resistance at the rocker tip. Dont mess with the pushrod spinning for feel because it takes too long.(even good lifters will bleed down at full lift) Repeat this process a few times in the next several runs (or dyno pulls) until everybody "settles down" and you have consistent zero lash feel at all rockers. After this you should be able to run it like a grocery getter but I alway look under the valve covers for "dead mice" following a heads up or hopped up run (nervous at 8 thousand). There is definate performance in monitoring max valve lift in an engine that would like another .150 or so if it could get it, at least that's what I have always thought. TT
