I currently have an Ls6 cam and pushrods and am upgrading to an F-13 cam. My question is should I use the stock legnth pushrods or the slightly longer Ls6 pushrods? Any help would be appreciated.

 

I would like to know this also.

 

X3 on wanting to know. I've been hesitant to install my '04 LS6 cam because of this. I have a set of 7.45" Trick Flow's. . . is this the correct length?

 

I don't know what length you will need, but the LS6 pushrods aren't longer the valves are. From the smaller base circle and the stock length valves of your head, I would think 7.425" but to be sure you need to use a pushrod length checker.

 

+1 on the pushrod length checker.

 

Ok, I sent Allan at futral an email and he said this "If stock heads\valves, you will need 7.425" length pushrods." This is for the std lift f-13.

 

7.40 here with my F13 cam The looser you can have your valve train in your car the faster your car will run. Good Luck
