Wow INTEGRA, you sure are perfect. Whatever you says goes and is the absolute perfect thing.

For the money, I would definitely get the SH 8-Port engine or the XTM 457 6-Port engine. I love SH engines and both are SH engines (or Golden Lion if you dig deep enough).

You can pick either one right now for $99.95. Their usually double that.

BTW, I have a XTM 457 and I am on my way to 10 gallons with the same piston, rod, and sleeve and it still idles perfectly, and is still faster than fast!
