Re: V-12, new build, tough start, fuel volume, timing?
I have calculated my fuel usage several times over the 45 years I have owned my 1960 3/4 ton 305 A with the stock 1bbl Holley. It has worked out to 10 MPG at 50 MPH on the highway or 10 MPH in the woods.
I don't know much about V12's but I sure hope they do better than 5 MPG.
But even at that milage, 50 MPH would be 10 gallons per hour, surely within the performance of a stock mechanical fuel pump.
That 100 GPH would empty the fuel tank in about 10 minutes.
