If you didn't read the thread I did and all I found were a bunch of inconclussive answers. Search this yourself if you don't belive me. By the way no need to come off as an ***.

 

I can never get a straight answer on the stock pushrod length. Some say 7.38 some say 7.40. I'm running 7.375s with stock cam and heads chopped off roughly .020". It's quieter in the engine bay than stock.

 

That was my point. All of the seaching I did on this forum and others I couldn't get a straight answer on the correct pushrod length I would need. So I figured that if maybe I started a thread asking the exact info I needed I would get the answer I was looking for.

 

Does somebody have a stock pushrod they could measure??

 

i have a ton of them... but my dial calipers i use for reloading only go to 6"

 

I am going to measure one when I get it out and will let you know.

 

this question is like the ole chicken and egg question. i asked and research pushrod length for ls6 cam in our motors and even the cam head guru's don't have an solid answer. most will say go for the 7.400's i don't think anyone has ever took the time to do any exact measureing. most just take word for it and go with that, then say its the right way cause thats what they did. i was dead set on 7.425's and wound up with 7.400's my rackety *** knock noise went almost away once i installed the new cam and pushrods. if you want to take time and bleed down the lifters and do everything perfectly accurate, then let us know what it is and maybe we can sticky it in big bold *** letters.

i had one company tell me to go like 7.450 and another tell me to go shorter than stock.

 

Did you get that measurement?

 

I have the same deeply haunting question with my new cam. Except it's opposite- I'm putting an aftermarket cam in my '04 LS6 engine.

Just measure the new cam base cirlce, pull the old one out, hurry up and put the new one in, and then measure the old one. Problem is that you have to wait to order your pushrods

 

for you i would just look over on ls1tech and ask those guys. being that they do it all the time it should be an easy find.
