ok i have a stock ls1 and plan on putting a cam in it this weekend

the cam is a comp xer 224/224 .581 114lsa

what size pushrods will i need?

i have 8 7.400 right now and am about to order 8 more but wanted to check to see if 7.400 is the size i need?

thanks for any help

 

I also have a stock block &a cam close to yours goin in. I was told to use 7.400".

 

My cam's 225/580 114 and have 7.4's in it now. That should work fine for you.

The only way to get exactly the right size is to use a pushrod checker.
