Looking at dropping GMPP 1.6 RRs into my 96Z. Wanted to know what the best replacement pushrod would be. Are hardened pushrods going to worth the money on a stock cam? If stock pushrods would be best.. what is the GM P/N?

 

For about $100 you can pick up a set of Comp Magnum pushrods that will handle any spring pressure on a hydraulic roller and most solid roller setups.

 

I have a set of hardened push rods from my 94z with 9000 miles on them. They are in perfect shape. I will let them go cheap.

I think I read somewhere that the stock 94-95 pushrods were hardened but the 96-97 rods were not? What's up with that?
Any difference in size or diameter between the two? Does anyone have GM part #'s.

 

I think I found the part # for a set of 93-95 pushrods in one of Shoebox's old posts;

P/N 12371041 (about $21 on GMpartsdirect.com + S&H)

The fact that there are different part #'s for the 93-95 and 96-97 pushrods would definitely lead me to believe that there is some difference between the two. Can anyone tell me why GM would go w/ hardened pushrods but then switch them out for something else in 1996? Seems wierd....

 

Can anyone chime in on this one?

 

I guess GM decided hardened pushrods werent necessary.They cost more too.FWIW I am running the stockers with a small cam.

 

Does anybody have a P/N for the 96-97 pushrods?
