Subject: Re: LT1 Cam Install Help Needed?? by rickreeves1 on 2009/2/26 18:34:20 Yesterday went pretty well. I checked the spring height with my micrometer and everything was ok there. I then Installed all my new studs and springs. I also checked for pushrod length. Maybe someone can verify I did it correctly... I set my pushrod length checker at the stock height of 7.200" and installed it with the roller rocker and weaker spring from Ace hardare. I could only install one side of the retainer to fit the checker in there.

I then placed the rocker arm on the stud. I twisted the pushrod checker in my fingers while tightening down the rocker arm bolt. When the pushrod checker was no longer able to move I tightened the nut an additional half turn then tightened down the retainer.

It was more toward the exhaust side indicating that the pushrod length was too long. I kept shortening the pushrod length checker and repeating the process until the wear patter was in the middle. This was what the wear looked like the last time I did it. I'm bringing the pushrod checker to a local machine shop today to get it measured with a digital caliper. Most auto stores I tried did not have one long enough. I'll let you know what lenght it is.
