I'd leave it on gas. Yes you'll make more power, run quicker & cooler on alcohol, but the tradeoff in terms of maintenance and wear just isn't worth it. Especially on a pro street car. Alcohol carbs and injection idle fairly rich to help throttle response and starting, and WILL dilute/milk the oil. If set up properly, allowed to warm up and not cooled too quickly, it's not as bad, but it's still there....basically, if you want an engine that will run for several seasons without any major issues, run gas. If you want that extra tenth or two, the superior cooling and consistency, and don't mind completely freshing up your engine every year, run alky.

A properly set up alky carb or injection will not milk the oil
My apd 950 1050 and 1150 never did
my toilet didnt
my terminator doesnt
My vote will always be for alky to much plus side.

I agree that a properly set up carb or injection won't milk the oil....much, and if your good enough to get it set up correctly right out of the box, which you apparently are, then SWEET! I've seen hundreds, yes hundreds of people changing the oil on their methanol fueled cars at the track after each event, and most of the oil looks like a milkshake. Perhaps milking isn't the correct term. You'll get enough fuel in the oil to eventually damage bearings, not to mention corrosion in the rest of the fuel system. Yes I know, if you maintain that stuff, keep the cell full, oil the pumps when empty,etc, most of that can be dealt with. My point is, on a pro street car, which this is, the additional maintanence is too much for the benefits of alcohol. You'll still be freshening the engine every season or a least replacing bearings: unless you feel lucky.....
