So, looks like I am slowly finding the answers to these questions. Many thanks to Mr. Paul Abbott of Performance Oriented, once again.
Per his website and a quick email, one needs 0.1 gallons/hour fuel delivery per horsepower. So, if the 3.2 at 10.5 compression ratio, twin plugged, puts out, say 250hp (hoping for more obviously!), we would need 25 gal/hr of fuel supply.
See here:

Looks like we would be short at 21 gal/hr from the factory pump.
Hope this helps someone.
