sparks piston

[trost66]

I was thinking about getting the sparks 13.8.1 high comprision piston. I just wanted to know what other people thought that are running it now. Does it make a big difference

Is Sparks even shipping there pistons yet. I gave up on them a long time ago. They kept on giving me the same ole run around... call back in another couple weeks... Yeah rite, I played that game for a couple months. I wanted the 12:1 though.

Yeah, it sure did. Great power throughout!!! I think the pipe probably made the biggest difference though.
