Thread: Piston Selection Keith Black Forged or Speed Pro Forged

Well, you've certainly done your homework. The link was impressive and I'm hard to impress.

Your point about weight is well taken. The motor should be easier to balance with the lighter piston/pin and should spin up a little quicker as well as being a little easier on the crank, rods and bearings.

On a low rpm street motor, I prefer the thicker ring for better sealing, but if you're gonna spin the motor up some, the thinner, lighter ring will stay seated on the bottom of the ring land better and stave off flutter.

As far as piston deck height, I usually want the tallest compression height I can get in order to prevent excessive cutting on the block decks to get where I want to be. In this case, 0.006" difference ain't gonna make or break the decks.

All things considered, I'd go with the lighter piston.
