Need advise on getting power to the ground

In terms of technology, the engine might be a bit past anything I'd want for the street. But as you say, you will be de-tuning it. Alcohol needs more static compression and my guess is it has gas ported pistons which may make things hard. What head package is on it? What oiling system? What water pump and cooling system? It might be easiest to just replace the pistons, roller cam, and springs if it's a wet sump and doesnt use the block and head coolant lines. That would make it more fun and more reliable on the street. I think it would be a cool thing to have. But there are some real reasons why you dont want to drive it as built on the street: Valve spring breakage, top end oiling issues, oil pan fitment, clutch setup, header type, hood clearance, extra coolant plumbing, etc.
