I was wanting to know the max shot on these pistons. Alright, I know an LT1 can handle 150 shot from the factory, probably more if your brave enough, but these pistons are suppose to be stronger than stock cast pistons so I was assuming the same 25-150 shot max.

I also searched and seen people saying 150 is max unless you run bigger, then you need forged. I am not planning on running a major shot, prob start out @ 50 then move to max 100 if possible. Thanks

 

You shouldnt have any problems with a 100 shot. You could prolly even do a 150 every so often. I know there is alot of people on here that spray 150. Just depends on how careful you are. I do beleive our pistons are stronger then regular cast pistons. Its also other factors besides the pistons that might cause a problem.

 

stock pistons are hypereutectic

 

From what I know stock pistons are a different cast and not hyper.

 

I have the Kieth Black Hyper Pistons 4.060 with Hastings race rings, Powdermetal rods, and cast crank.

 

My bad, they are the same, didnt know but I know there has to be a diff between the KBs, suppose to have better oiling + mine are Floated and 2 valve reliefs. U learn something new everyday, thought I knew everything about the damn LT1 lol.

 

I sprayed my hypers with a 150h shot.
