No one will care, its a stock replacement part that gets you no added bonus over others.Quote:

Works for me. Just didn't want to buy parts and not be able to participate :)Quote:

Well you had a point. My only purpose in upgrading to hardened rods is for peace of mind. We'll see what the official thingymaboob is.Quote:

Now if you go and get some exotic pushrod that weighs way less, you might be in trouble. I'm sure the rules makers will chime in but a hardened pushrod simply helps with longevity, it doesn't add power.
What material and wall thickness are the pushrods you bought? An argument can be made that a stiffer pushrod would help with valve train stability and help squeeze out a little more power. I agree that if it's just a normal mild steel hardened pushrod it shouldnt be an issue, however this is one of the most restricted classes that the shootout has and it has to be looked at pretty closely. 5 to 10 horsepower can be the difference between a W or an L.
I haven't purchased any rods yet. But if or when I do, they would likely be 7.2inch chromoly with .080inch wall thickness.
I completely understand that this may give an advantage in some cases that's why I wanted to ask. I know the shootout is more about having fun and that's why I want to go next year. If this is something that won't be allowed I am totally fine with replacing with steel gm performance ones.
Well it's not that they're not allowed, it's just that push rods are not clearly listed in the rules as to what guidelines they have to meet except for the general internal engine modifications of being similar weight size strength ETC . The rules do allow for roller rockers, even non self-aligning ones which would require guide plates which would require hardened pushrods. I think it's just something we'll have to clarify in the wording of the rules
I appreciate the clarification. I just don't want, or like, to read between the lines. I know your jobs are difficult enough and having people pick at the rules doesn't help.Quote:

I think that it would be good if aftermarket EFI, carbs, and 24x were at 3100 lbs as they all have pretty much the same potential. Allow a 100 lb weight break for a stock PCM.Quote:
