Not Ranked
I can't answer your question.
But I respectfully question how you made such power, using no more than 5000RPM and a 'reflowed' 650.
A displacement of 557" inches would be needed to easily produce 740+HP at 1.4HP/CI. Even if modified to 900CFM, (impossible without a larger baseplate and throttlebody) it would be hard pressed to get there. But the RPM limit makes no sense.
Hope someone can help with your request, but I'd be most interested in your complete combination.
Thank you,
