Judging by the photo the compression is between 7:1 and 11.5:1.

You can run nitrous depending on you heads and the piston material. Also depnds on how much nitrous you use.


Vague question gets vauge answer.

Have fun.

More info is needed to accurately guess the compression ratio.

Piston part number to determine the CC of the dish and VR's
Head combustion chamber CC
Head gasket compressed thickness
Actual deck height of the piston as installed in your block.
Crank stroke
Block bore
