Description

The Silv-O-Lite S1442.060 is a cast aluminum piston designed for 1969-1978 Chevrolet and GMC trucks with a 5.7L/350 Chevy small block Gen I V8 engine. This piston features a flat top with no valve reliefs and a bore size of 4.060 inches. It includes a press-fit wrist pin and is sold individually.

These OE-type pistons are heat-treated and machined for strength and durability, offering tighter piston-to-cylinder wall clearances and longer life. The piston head volume is +4.00cc, with ring grooves measuring 5/64 in. x 5/64 in. x 3/16 in. This piston is a direct replacement for original equipment number 3947746.
