I'd make certain of the fuel supply.
We sell 170+G.P.H. Carter pumps for s.b. Chevy and Ford NASCAR applications - - but not for the FE. Barry Grant actually modifies Carter pumps by welding the fittings on and porting the inlet/outlet passages.
A true 120 G.P.H. should support an awful lot of power. Figure on fuel weight of 6 pound per gallon, thats about 720 pounds of fuel/hr. Since brake specific would be .5 or better, that traslates into 1440 horsepower - yikes!
But - - nothing is as easy as it looks. Turns out that fuel pumps are rated for flow at zero restriction. That means no fuel lines, and no line pressure or resistance. If memory serves well, the old Holley 110 GPH electric ran about 70GPH when working against a regulator, which is much more realistic - still without lines and such. Even there, you could easily support 600-700 horses w/o fear. |
