Over the years, we’ve built dozens of small-block, big-block and LS-based engines where we have set custom ring end gaps. We must admit that we rarely check the end gap on the two small stainless ...

But when done right, piston rings can create a power advantage by maximizing dynamic engine compression while still maintaining good oil control. This involves both proper selection for the intended ...

There are three things an engine needs in order to run: fuel, spark and a place to burn. This place, a combustion chamber, must be fairly gas-tight or the pressures developed during burning will be ...
