i dont know much, but i think it might be from an LS block, there is a spot on my block that says pr4 if i remember right

 

[onetyme_sam]

sorry, let me specify more, my b18a

 

[chasengnouc]

LS from 90-93

In that case, what are the pistons in a b18b? I thought those were pr4's too

thank you all for your input.

hey B, is there any way we can get add a Piston guide in the reference section? if i get a chance i'll put one together unless someone beats me to the punch. it just may take me a little while to do the research cuz my free time is very limited right now.
