Do not know the piston/cylinder wall clearance but I want to say my ring gap was .020-.023ish. It was on the wide end of the spec I remember that.
3.23 cam with the car, I would like to get into some 3.73 or 3.91
27.05 rear tire height
Not sure on weight
So far I’ve taken it up to about 5500 with only 300 miles being on the build
