George,

I really don't have much input, as I'm not to the cam buying stage yet. But Delta Cams on the west coast will custom grind you a cam, if you supply info. If I'm not mistakek, even without a core, it's only like $150? You'd have to do some research, call around...or maybe someone else will chime in.

The 3x1 Offy will be a challenge to tune, but when it's done, I think the look and spread secondaries will be well worth it.

Any plans for mufflers?

Also, have to say welcome to the inline community, to a fellow Wisconsinite. \:\)
