Got a set of Sealed Power Speed-Pro 383 Hypereutectic Pistons with Pins Locks and Molly Rings that got cranked on about 6 or 7 times for about minute a piece: the engine never turned the thermostat over. We noticed an oil leak around the rear main seal area and shut the project down. $125 or trade for tools 5.0 parts text/call @ nine-$even-ll-8-lll-$ix-5-l-ZerO-lll , Items shown in photo.
PLEASE NOTE: These pistons are weight-matched sets therefore can only be bought in a quantity of 8. If you order just a single piston it may take up to 2-weeks to get.
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.
