Finally figured out the correct cam, and timing. It's really close, probably won't change it much. 3 lobes, rotating the same direction as the crank, at a 6:1 ratio. BDC isn't the same for all cylinders. Some will be on the way back up before the valve opens so they will probably 'pop' when the valve opens, I'm kind of concerned that this will cause unnecessary resistance, although not much; and I don't think there isn't really anything I can do about it.
What can I do about cylinder compression ratio? I'm thinking of making a spacer at the top of the cylinder under the head; but that will make it difficult to align the head with the crank case. Or maybe something between the cylinder and the crank case.
Learning a lot on how to use my CAD program, probably more in the past week than in the 6 years that I've had had it!
