I need some lifters anyone know someone with some that they may have forgot about. I have check all of the for sale sections and there is no one really selling any. The one guy that has some for an LS1 does not know a whole lot about the history of them so I am not going to get those I do not think....

make sure the pushrod is in the indentation on the rocker and torque it properly, if you want to feel better rotate the engine around with a socktet on the crank and recheck the rockers. its really extremely easy, just sounds complicated.

so there is no valve lash to set huh.......I am being told that I do have to set it. But this is from a LT1 guy.....I do not want to insult you I just do not want to mess up the motor. Also aprox what is the preload on the lifters at 22ftlbs

Allways set preload (torque rockers) at base circle of cam.
While rotating motor clockwise with long pull handle attached to the harmonic damper bolt. Adjust both intake and exhaust valve directly after each intake valve closes on compression stroke at TDC. After adjusting the number 1 cylinder move on to the next one using the firing order sequence. I forget what the firing order is for the LS1.
There are other easier ways of doing this, but I do not have the time to tell you.

the process you describing isnt used on ls1's, the old process of tdc on compression is like intake 1,4,6,7 and exhaust 1,5,6,8 or something like that but thats not how to do the ls1's

Just an FYI since your new to this. You must pull the heads on an LS1 to change lifter's. Just thought I would throw that out there in case you didn't know

everything is good to go thanks again guys for all of your help......I may be asking a few more questions here in about a month on some things that I need to do to do my cam swap. I want to do that myself aswell. I am enjoing learning all of this new stuff and how to work on my car. So far I have put a ford 9" in my, car swaped from an auto to a m6, changed pushrods installed and removed a supercharger, pulled an engine from an LT1 put an engine back in an Lt1, Installed a 255 lph fuel pump (cheated though used the trap door methos) Now I am ready to install the cam and maybe later mess with the bottom end but who knows
