Hypothetical build. Rules say single carb. Can be a dommy. Can use any heads a460 and down. No boost. No nitrous. Must pull 15” vacuum at 1000 rpms. No alcohol but can run any other fuel. Using a factory block what’s the most realistic hp possible?

So you could run a mixture of gasoline and nitromethane (yes, you really can do that for a significant power gain, though I gather it's somewhat risky). Might could also have a cam ground that lofts the lifters off the lobes in a controlled fashion above a certain rpm, thereby giving you more duration and lift than would be possible otherwise.

If you're really wanting to get every last hp, you could still mix nitromethane in with racing gas. Not saying you SHOULD, just that you can.

EDIT I was wrong, I should have said nitroPROPANE.

I’m new to race engines. I’m currently using Sunoco 114 and was using C12. I switched to Sunoco because it’s closer. Here in central WV there is absolutely no place to source race gas. Do I need to stay away from Sunoco???

You are better off to order drum of VP than to get some jugs of Sunoco
