Okay, I've got a 5.3L (2002 model) in my 67 C10.

I bought an ASA GMPP Cam, LS6 yellow valve springs, ARP rod bolts, LS2 HD timing chain. I measured the base circle on the ASA cam and its about .030" smaller then the stock 5.3 cam. I've been trying to find STOCK pushrod length on the LM7 engine. I've read that people are using 7.425" pushrods, which are .025" longer then stock. (for LS1??) I think these are the ones I need. Can anyone chime in and verify this info for me? Again, LM7 5.3L vortec, 2002 model.

Pace parts sells stock replacement LS pushrods as a 7.325" length..so i'm now confused what is correct.

thanks

Brendan.
