A forged 360 Mag piston that comes in around 8- 8.5:1?

I've done some searches here and with google but really have not found a recommended part # of a Forged piston that will be in the 8s for compression. Will be used in a 360 magnum with Iron magnum heads and a Weiand 144 street blower. When I look at piston specs and the piston states a dish that creates a "+" in the combustion chamber volume the advertised static ratio for that piston is still high for forced induction.
