If i put 03/04 cobra rods and pistons in my 99 with a procharger it would lower the compression right? and that would make it sluggish? We dont want dished pistons for our cars correct? just makin sure

YOU want dished pistons and lower compression because YOU have a procharger.

MOST 99 cobras are NA so dished pistons are bad for THEM

This is a common misconception and leads to low peak hp and low torque/pre-boost power. Lower the compression ratio to 8.5 from 9.85 will drop peak power 50rwhp. The boost will have to be increased to make up that power and that increases the power required to drive the supercharger. So, keep the compression stock or drop it to 9.5:1, no lower.

The 03/04 rods are great pieces and the pistons give out around 750rwhp.

^ agreed. i think -11cc puts you at about 9.1:1. with a centri blower i'd try to stick around 9.5 to 10.0, but the 9.1 will work also.
