Thanks for the response so far. Now I'm a little concerned. On the 01, which is ported, stock head, welded crank it has 135 in both. Runs good, should be about right, I assume. On the 94, it has a drag port, 17cc domes, trued welded crank and 230lbs in both cylinders. High numbers from what everyone else has posted to date. Anyone have any numbers like this?

Thanks.
