by Mike Mavrigian FILE FITTING THE RINGS Because of our over-honed cylinder diameters (4.263″), standard size rings wouldn’t work, so I started with a set of Total Seal rings P/N CR7190 35, supplied with our Diamond pistons. These are intended for a bore diameter of 4.268″ (1/16″ top, 1/16″ 2nd, 3/16″ oil), requiring a custom [...]

Here’s an underside view that clearly illustrates the side relief/short pin design. Naturally, this also reduces reciprocating weight as a bonus. As you can see, the compression height resulted in the [...]

In an effort to fit the ring package into an ever-decreasing available piston area, oil rings are getting thinner, to the tune of 2mm or so.
