Lucky dog...LOL...
If you go stock stroke or 4 mil, all you need is cylinder, head, pistons, reeds and intakes.
You'll have to get exhaust to fit small or large flange, I believe they make both flanges for the Cheetahs...depending on what you get.
For 7 mil or bigger, you'll have to get your cases trenched....for the longer stroke.
4 mil cheetah is what I'd buy...
However...you're in MI, we have 3 good sand drag tracks and Silver Lake...why don't you build a drag banshee?
You have two others, one could be a trail, one a duner/partial drag bike and one a full on drag bike.
Best of all worlds...
If you decide to go one full out drag race, a DM Cylinder on methanol is the way to go. It's expensive....but, setup properly, you'd be able to beat 95% of the bikes out there...if not more.
My next motor will be a 10 mil DM....
