Can I make this work on pump gas?

Not sure if this is an option in your area but if you re-jet it you can consider running it on E85 as well. I understand as long as you don't let it sit for long periods the requirement to run stainless steel for your fuel system is just a myth. I am doing this with an old project I have that I built 12.5:1 (young, stupid and HP hungry) and currently needs race fuel.
