Here's a perfect Set of 8 Pistons and pins (That we are selling as singles, but you get FREE Shipping after the 1st one purchased) for Small Block Chevrolet Engine Flat Top 2 Valve Reliefs, Coated Skirts and .060 oversize. Final Bore of 4.060". The original owner just wanted to upgrade to higher compression piston set. We were put in charge of selling them for him. We're showing all 8 skirts and both sides and everything looks in great shape. As you can see we used an OTC Fixture for pressing the pistons off, and this supports the rod and zero pressure on the piston. (the only true way) to press pistons off with-out harming the piston. 

If you're looking for pistons with an unbeatable combination of performance and value, then Speed-Pro hypereutectic pistons are for you. These pistons are manufactured from FM244 aluminum alloy, which contains 16 percent silicon for greater strength and wear resistance. They're also molded in the latest permanent-mold technology to ensure the precise fit and tight bore clearances that today's top engine builders demand. They're ideal for use in high performance street, bracket racing, and oval track racing and will work perfectly with normal ring end gaps
