Official Release:

JE Pistons develops new lightweight pistons for high compression Small Block Chevy 350 and 400 cubic inch engines! 

JE Pistons has announced the release of a new lineup of lightweight FSR pistons for high compression Small Block Chevy 350 and 400 engines. The new “hollow dome” pistons feature a 2618 alloy forging with a dedicated undercrown design that closely follows the shape of the dome and valve pockets for maximum weight reduction. In addition, the FSR forging utilizes external bracing for improved pin tower support and a 2.250” wrist pin for further weight savings.

Nick Diblasi, JE Pistons Product Manager feels, “These new pistons are ideal for any high compression, 23 degree Small Block Chevy. They have been designed for the most demanding applications including 700hp 360 cubic inch Sprint Cars, drag racing and even high performance street vehicles.” Most popular combinations are available off-the-shelf, while additional combinations are easily made by custom order in as little as 5 days.
