Yes I do have a tow vehicle for towing it to the start and back from the return road.

No water will be needed. Alcohol (water based) is a cooling agent unlike gasoline (petroleum base).

If you do run water, make certain you have a vented catch can reservoir on board for expansion.

Are you only doing the 1/8th mile or going to run 1/4 mile too?

xlr8:
We will run both eighth mile and quarter mile.

I ran a SBC with Dart LIL M block and Dart Iron Eagle 230 heads. The block was fully filled with a hard block filler. We did NOT run coolant. Methanol fuel at 13-20 PSI boost pressure. The SBC does have a hot spot at the cylinder head center. We ran a solid copper gasket . The heads were cut with a receiver groove and the block o-ringed. No problems.The best performance was 4.50 @158 and 7.08 @ 193. I know very little about Pontiac but I can share my info with the Chevy. George

A lot of people run them dry on alcohol. I do not feel comfortable doing that and I bracket race sometimes to. So I run a small Honda style radiator with water pump and fan. I have complete control over water temps and it does not weigh much. Whole system including block takes less than 2 gallons of water. With this set up I do not need to be towed to the lanes and back, I can drive it all around and if I am hot lapping in later rounds my water temp stays in control. The cost is maybe an additional 20 Lbs? Well worth it to me for the security of protecting my motor and the consistency of being able to control water temps. By the way the little Honda radiator on Ebay with the fan was under $70 shipped.
