I'm putting the "Cleveland-in-a-Fox" idea to rest for now.
I just placed an order with Summit for a pair of World Products Windsor Jr. heads, Keith Black hyper. pistons and other goodies. I'm hoping for an honest 360-375 HP with my particular combo.
I'm going to be running a 750DP and the Weiand high-rise dual plane intake that looks like a mirror image of the Shelby GT350 manifold (good for about 6500 RPM). Can I rework the tank mounted fuel pump and lines to work with a carburetor by using some kind of low pressure regulator? If so, how do I do it?
Can I get the factory ignition to operate "open-loop" and have the computer set the proper ignition advance? If not, I'll probably use my old Accel 34 series dual-point. The advance curve is much easier to tweak anyway.
Thank you, Todd

Yes on the fuel pump and lines.
You will need a high quality billet regulator like a Aeromotive and rewire the relay.
No on the distributor and processor.
Your intake choice is not the best if performance is what you are looking for.

I have run this intake before in my Pinto and it pulled real strong through 6000 R's with a 4776 D.P. It also had a lot more torque than the Torker I started out with. To maintain a decent amount of low end
torque I'll probably stick to dual-planes.
The intake is an 8011 Action Plus series. I'll probably move onto an 8020 Stealth next.
Thanks for the info on the fuel supply, Moneymaker.
What intakes would you recommend? The camshaft will have about 226-228 degrees at .05 lift. Approx. .550 lift. 109-110 centerline. Hydraulic roller design. Keith Black flat tops. 58cc chamber volume Windsor Jr. heads for an estimated 9.6 compression if I get lucky. We'll mill the block if we have to, to achieve almost zero deck height.

Thank you, Todd

Sorry to be asking so many different things! I was wondering, doesn't the stock FI system use a return line to the tank? If so, don't I have to rig up some sort of metering block system in conjunction with the fuel regulator to send fuel back to the tank?

Aeromotive regulator is set up for return line.
180 degree intakes are great for low end.
They die over 6k typically.
I don't like them over .500 lift.
A Victor Jr. would be a better choice for over 6k RPM horsepower.
