that doesn't really tell us much. Assuming your base circle is the same as stock and you're running stock heads you'll need some 7.400 pushrods.

yea, just a small cam swap, nothing else. Comp Cam XR269HR

I was wondering that myself. I guess they aren't as strong?

Did a lil research...yea, go figure.
the main reason to change the rods is that the cam is most likely a smaller diameter, so you need a longer push rod to compensate.
So i just need to findout the diameter of my cam and stock.

First swap so I'm trying to gather the technical info. Valvetrains aren't something i've delt a whole lot with.

which reminds me i used stock push rods in my blazer with a 465/488 cam and Dart Iron Eagle heads. I should probably check on that too.

Your signature does not state what size engine you have. Assuming that you have a 5.3 liter, your stock cam has a base circle of 1.617". According to my calculations, your new cam has a 1.539" base circle. If you have any other questions, you can call Comp Cams help line at 1-800-999-0853.

just use 7.400 josh. most people get the new rods because they're hardened and there has been some stock ones bent...
