ive been looking to the future when i need some new pistons. these are the only ones if looked at so far.....

-Speed Pro, Lightweight Forged 8.97cr with 64cc chamber, -10.9cc reverse dome for $485 with rings.

-Speed Pro, Forged 9.72cr with 64cc chamber, -6.1cc,flat,4reliefs
for $260 with rings.

what do you guys think?

another question, if i use stock heads, will the CR of the pistons be less or more than if i used heads with 64cc chambers?

thanks for the help guys...

 

Stay away from a "lightweight" piston for a blower car.

i can get the same ones minus the lightweight.....

 

I don't know what CR you are looking for, but you are on the right track to stay away from the lightweight pistons. Are you planning a high boost setup? If so, you want to keep the CR pretty low for pump fuel.

yeah im just looking to the future to ad some more boost....
