142 ENGINES & COMPONENTS WARNING: For Proposition 65 information, see p. 183 Some parts are not legal for sale or use in California or other states with similar laws/regulations—see p. 183 for details. KB Performance Pistons Crafted from a high-silicon, heat-treated hypereutectic aluminum alloy, Hyper Series Performance pistons from Keith Black are light enough to improve throttle response, and strong enough to withstand the pressures and temperatures of competition. They feature fully machined crowns and valve reliefs, accumulator grooves, proprietary diamond- fi nished skirts, drilled oil returns, and CNC-machined pin bores. This all adds up to tighter piston-to-wall clearance for increased ring seal, reduced blowby, improved oil control, and no cold-start knock. Pistons come with triple spiral locks and work with press-fi t or fl oating pins. Sets available for 4- to 8-cylinder engines in standard or oversize bores, in a variety of fl at top, dish, and dome styles. Sets available with or without rings—Visit SummitRacing.com or call us to fi nd your application. Hyper Series Performance pistons, set...................................................from $381.99 Hyper Series Performance pistons and rings, set ...................................from $439.99 ICON Forged Pistons Get custom piston features at an off-the-shelf price! All ICON forged pistons are manufactured from lightweight aluminum alloys, with machined crowns, top land mini grooves for heat transfer and friction reduction, and accumulator grooves to maximize ring seal. Visit SummitRacing.com or call us with your application. FHR Forged Piston Sets These Formed Head Relief pistons have valve reliefs that are formed as the piston blank is pressed into the die. Most pistons work with press-fi t or fl oating rods, and use 5/64" top, 5/64" secondary, and 3/16" oil control rings (sold separately). Pistons are sold in sets of eight, include locks and pins, and are available in .030", .040", and .060" overbores. FHR forged piston kits ........................................ from $479.99 Premium Forged Piston Kits In addition to the die-formed valve reliefs, Premium series pistons have CNC-machined crown and valve reliefs, plus skirt and pin boss struts to withstand higher cylinder pressures. Some applications also feature lateral gas porting. They’re available in two aluminum alloys: choose 2618 for high-compression, boosted or nitrous applications; or 4032 for longer-wearing street engines. Kits are available for a wide variety of bore sizes and dome styles, and include rings, pins, and locks. Premium forged piston kits ....................................................................from $756.99 Summit Racing™ Coated Hypereutectic Pistons Our Summit coated hypereutectic aluminum alloy pistons expand less than cast pistons for tighter piston-to-wall clearances and reduced blowby. Each piston receives a T5 heat treatment for greater strength, plus a special skirt coating to reduce scuffing, seizing, and thermal wear. All pistons have diamond-finished skirts and use 5/64" top, 5/64" secondary, and 3/16" oil control rings (sold separately). Pins included. Available for standard 4.000" bores, as well as .030", .040", and .060" oversizes. Compression ratios listed are calculated with a .040" head gasket. Actual compression ratio will vary depending on cylinder head volume and deck height. Chevy 350 3.48 stroke/5.700" rod. Compression ratio: 8.5-10.5:1. 6.0cc 4-V flat top. Compression height: 1.560".
