350 ci SB Chev - Flat Top Hypereutectic Pistons 385 c.i., 4.040" bore, 3.750 stroke, 5.700" rod length, -5.0cc dome volume

Available on both hypereutectic and POWERFORGED pistons, DUROSHIELD is an exclusive moly-graphite skirt
coating that extends engine life and essentially eliminates scuffing. This technologically advanced coating is precisely applied to the piston through a computer-controlled process.

DUROSHIELD skirt coated pistons:

• Reduce friction for increased fuel economy and horsepower
• Essentially eliminate scuffing and wear
• Prevent damage from inadequate lubrication, especially at start-up
• Improve cylinder sealing for less blow-by and more power
• Require no increase in skirt clearance
