Just to clarify, are these blocks already assembled, i.e., are these the only parts that can be used? Reason I ask is because I need -5cc pistons.

 

They are assembled shortblocks with that particular piston already with them.

 

What would the compression ratio be with stock heads? I'm looking to use the short block for a blower application.

-B

 

Roughly 10.28:1
I calculated it with a .050 thick gasket and 58cc on the chamber.
