pistons

Piston rings have a dictionary all to themselves, and it’s important to be familiar with the terms before you begin an engine build. The piston pros at Wiseco put together this short glossary of important piston ring terminology so you’re in the loop…err…ring, when it’s time to install your pistons.

[portfolio_slideshow id=56479] When it comes to pistons, the most common arrangement you’ll encounter makes use of three piston rings — compression, second, and oil. Today, we’re turning our focus to the areas of the piston most associated with the rings: the ring lands and grooves. Piston ring lands are the areas of the piston between the piston rings.

You’ve got questions. We’ve got answers—the Summit Racing tech department tackles your automotive-related conundrums. This week in our Mailbag, we’re focusing on connecting rod length and piston wristpin height. Q: I have a 1972 Ford 302, bored .060-inch over. I took a 351W crank and had its main journals machined to 2.2486 inches to fit the 302 block

When you shop for high performance piston ring sets, you’ll no doubt find there are many different sets and styles available (no big secret). And many of these ring sets are designed to be hand-fit to each cylinder bore. Typically, file-fit rings are designed so they measure 0.005-inch oversize (obviously larger than the cylinder bore size). By

You’ve seen it—somebody trying to install pistons and ending up with pinched or broken piston rings or so much oil in the bore their shoes are drenched. It doesn’t have to be that way if you use the easy-to-follow procedure outlined in the photo captions. Happy piston installin’!   [portfolio_slideshow id=17469] Tools Required Lint-Free Towels

Got questions? We’ve got the answers—the Summit Racing tech department tackles your automotive-related conundrums. This week, we discuss the basics of compression and how it relates to your fuel octane. T.C. • Dayton, TX Q: I have a 1993 Chevy Silverado Z71 and according to the repair manual, my small block’s compression is 8.2:1. What
