I am doing a budget 383 and was wondering what is your thought on spraying either speed pro hyper piston or keith black hyper pistons 150 shot at most. I dont want to spend 500 on pistons if one of these pistons would work. Thank you

 

Anyone has any input.

 

A friend of mine ran a 125 shot regularly on the KBs with no prob.

 

I sprayed my stock motor 150 for over two years. You should be good with the right tunning.

 

I've been spaying my stock shortblock with a 150 shot since 1999. So far so good.
