On the 02-04 z06 cam what lengh is the pushrod for that cam?

 

what heads? what length valve? which rockers?

a stock ls6 head with ls6 valve will use 7.400 pushrods.

a stock 5.3 head will use 7.425

 

317 heads stock valves and stock rockers

 

7.425 assuming the heads aren't milled and you're using stock lifters. not a bad idea to chck it out though

 

I think 7.425 due to the smaller base circle. Search on LS1tech.

For sure get one of those for your toolbox!! You can get in the right ballpark as well by using a pushrod of known length and using the method of counting the number of rocker bolt turns from zero lash to 22ftlbs....but again, that is not the most accurate method.
