Description

The Silv-O-Lite Cast Pistons 1271.STD are a set of OE-type pistons manufactured from cast aluminum. These pistons feature a flat top design with no valve reliefs and are machined to produce a unique diamond finish with exacting skirt tolerances. They are heat-treated for strength and durability, offering tighter piston-to-cylinder wall clearances and longer life.

Each piston has a 4.250 inch bore and a 3.375 inch stroke, with a 6.358 inch rod length. The ring grooves are 5/64 in., 5/64 in., and 3/16 in. This set is sold as a quantity of 8 and includes wrist pins, but not wrist pin retainers or piston rings.
