whats the compression on the 383? really with out lowering the compression, I wouldnt go anymore than 6-7 lbs and if you over 10.5:1 I wouldnt run boost, boost and high compression dont get along to well, you will never keep a head gasket in it.

you might loose about .5 off your compression by opening the combustion chambers up but your not going to gain that much. you need dished pistons to lower the compression enough to run boost. and to run boost you need to have the ring gap set bigger, if the rings are set up for a N/A engine there set farly tight you will end up breaking a piston ring.
