Pistons? Which brand is your preference?

This winter we at Classic V-Drives are building Big Block Chevrolet Blower Motor (Engine). It is going to be used in a 21' Connolly Ski Bum (Day Cruiser) V-Drive, as a river/lake boat and not a race boat.

Engine Specs (So Far): 8:1 compression, Dart M Engine Block, Bryant Billet Crank, Oliver Max Plus 6.535 Connecting Rods, AFR 385cc Rectangle Port Aluminum Cylinder Heads, ISKY Hydraulic Roller Cam (unknown specs so far), ISKY Ez-Roll X Solid Bushing Roller Lifters, Whipple Intake Manifold/Intercooler Combo, dual 1150 Holley Dominator Carburetors and with hopefully a Whipple 8.3 liter Blower (Supercharger).
