Calling all Chevy small block builders! This piston and ring set is exactly what you need for that 350 engine project. You get EIGHT hyper-eutectic pistons with coated skirts plus matching moly rings - perfect for 5.7L 350 Chevy small blocks from 1968-2000. These bad boys feature a .275-inch (that's 11.8cc) dome top that gives you that sweet 11.9:1 compression ratio. Whether you're building a street machine, strip dominator, or light race engine, these pistons can handle the pressure. The ring grooves are sized at 5/64\, 5/64\, and 3/16\ with a .927\ pin diameter - all the specs you gearheads care about. They're designed to work with 5.7\ rod lengths and 3.480\ stroke, and guess what? Both press and float pins are included along with lock rings, so you've got options. Super important - make sure you click the right size before adding to cart! The +.030 means 4.030 bore diameter, but double-check what your engine actually needs. These aren't some cheap off-brand pistons either - the hyper-eutectic construction with coated skirts means better durability and heat management. The moly rings seal tight for optimal compression and oil control. Seriously, if you're rebuilding that 350 and want reliable performance without breaking the bank, this set has your name on it. Perfect for that weekend project car or that engine you've been meaning to build forever. Get ready to hear that Chevy roar!
