NEED ADVICE

I'm not an expert on fuel needs especially for E85, but from what I've seen I highly doubt 1200cc is enough for 650 on E85.

I am 100% prepared to buy ID 2000's if necessary. Will the pump support that power though??

Over 500-550 on e85 is double pumper territory.

I agree with both of the statements above. On E85 1200 CC are not going to be enough for the power you are looking for. Also, if you want to be making 650 you are going to need a double pump setup (anything over high 500's pretty much requires it).
