The Old Guy Posted January 14, 2004 Share Posted January 14, 2004 Unless you are going to Bonneville ,you will have all you need from a Holley Blue. Link to comment Share on other sites More sharing options...
2seater Posted January 15, 2004 Share Posted January 15, 2004 The basic rule of thumb is it takes 1/2 lb of fuel per hour to support one horsepower. At approx. 6 pounds per gallon of fuel, 90 GPH works out to 540 lb/hr, or enough for over 1000 hp, assuming there are no restrictions and the fuel pump can actually draw and deliver that amount of fuel through the system.

72electra Posted January 19, 2004 Share Posted January 19, 2004 Where did you find a dual 4bbl intake for a 455? I am building one up also and am interested in this setup. Thanks: Marty Link to comment Share on other sites More sharing options...
