KB Hypereutectic Flat Top Pistons - SB Chevy 350 - 5.7" Rod Length, .040" Over Bore Size Shift Light Tach takes the guess work outModern piston design locates the top ring higher for improved performance. a high top ring operates at higher temperatures and requires a larger top ring end gap. To find the proper ring end gap, multiply your bore size by the ring end gap factor listed on the chart (i. e. , Street Normally Aspirated 4. 000" bore x . 0065" gap factor = . 026" total top ring end gap). Your hypereutectic performance piston will expand less than typical cast or forged
