another what will it run after this set up?

..... but i think a 28" tire would be better than the 29.5 with the 727.....

I don't understand this statement. I would think you would want a taller tire to make it easier to hook, more side wall to absorb the shock of launching the car. I have always used the tallest tire I could fit under the car for this reason.

Could you please elaborate, maybe I'm missing something.
Thanks
