I just opened my new Comp pushrods from Summit Racing and 6 of them are BENT (have I told you all about my recent Summit Racing nightmares.....I'll have to sometime, let's just say that it'll be a cold day in hell before I order from them again)....bent to the point that it is plainly visible to the naked eye, you roll them on glass and they wobble like crazy, since the cam is only a 210º/218º .531/.531 lift and the truck will never see more that 6000rpm's do you think the stock pushrods will live for awhile until I can get these replaced with a hardened set ??

I realize that stock pushrods aren't the best even with stock cams but the RPM's won't even be what some stock motors see...and since it's pretty impossible to miss a shift with an auto I won't run the chance of over-revving the motor.....

 

i would wait. but thats just me. i think that you will be okay if you keep it under 4800-5000 rpms. i would never rev a cammed motor with stock push rods.

 

Stock pushrods are fine, especially with that cam. Pushrods are pretty easy to swap out too. I'd go ahead and run the stock pushrods. I ran them on my last truck with the LS6 cam. It wasn't much differnet than the cam you have planned to install. The pushrods took 6200 rpm shifts, nitrous and 80K miles with no problems.

Just hurry up an get the heads swapped. Enough summit racing ate my homework excuses for now.

 

How long you planning on running them? Can't you just get another set from someone a little more reliable and then sell the ones you are trying to replace? You should be ok .

 

I just read an article in Hot Rod about a Carb'd LS1, they flogged it pretty good with stock pushrods.

 

 

I would like to say that I'll only run them a few hundred miles.....but knowing my luck it'll be 50,000 or something stupid like that

I REALLY wish that I didn't have the Summit Racing excuse....I'd be a much happier person right now

 

I've heard from more than a few people that the stockers are fine.

 

i run stockers to 6400, limiter is at 6700. I've heard its better to bend a pushrod than to bend a valve.

 

Some racers prefer the stockers saying they would rather bend a stock pushrod than suffer valve damage with a missed shift.

Fact is, your cam will put the pushrods under less stress than a stock Z06. The Z06 uses the same pushrods you have. GM expects those cars to go 100K+ miles.
