need pushrod length info please....
 

I just purchased a Comp Cams XE 224/.563/112. i plan to install this in my 04 5.3 silverado. does anyone know what length pushrods i need to get? also, what gaskets do i need to purchase? any tips on the install? thanks in advance for any info shared....

i beleive the pushrods you need are stock length.. get them from thunderracing.com

7.400 is the stock length i beleive.. i have a similar cam and thats what was recommened for me. As far as gaskets go... you might be okay, but if you want, replace the head gaskets, timing cover gaskets, i beleive thunder racing also has a gasket install kit. check them out.

Why would he replace the head gaskets??

I think stock pushrods are 7.375. I believe you need 7.400 (if I remember what I have. Call Futral Motor Sports, or Thunder Racing or Comp, or anywhere and they should be able to tell you. Also, Ive done a few cam swaps :jest: In these trucks, and never replaced a single gasket, just be careful when you tear it down. These gaskets are designed to be re-used to cut down on shop labor or some B.S. like that

stock push rods are 7.40

Stocks are close to 7.35

It depends on that cam really. If the base circle is the same as the stock cam, you will be in good chape, but if it's smaller, you need a longer pushrod.

If it's the same and you go with 7.4's, it will run bad. It will have lack on the bottom cause the valves are hanging open all the time.

well I pulled my stockers out and put them up against the 7.35 rods and the 7.35 are shorter than the stock ones. So I would say the stock ones are 7.400.

Thanks guys for all your help. I'm going to cal thunder or comp tommorrow. And white1, i'm going to try to save my stock gaskets as well. Thanks again...

good luck with the instal enjoy your cam!
