Just for fun, What do you think it will make

With the combo you listed, you should be close to 600 or maybe a little more. I would go 950-1050 on the carb though. We just got our carb back from Pro Systems yesterday(E85 conversion, custom tune) Hope to try it out this weekend. Pro Systems said We would need a 220gph+ fuel pump, so I went with a 280 BG. I've also heard E85 is worth a tenth or two over race gas. I guess we'll find out this weekend!
