How can I get better gas mileage in my 460?
Change the filters, fluids. Consider synthetics for the differential. Keep the tires inflated. Don’t haul around extra weight when it is not necessary.
Is the Ford 460 a reliable engine?
Overall, Ford’s 7.5L 460 engine is extremely reliable. As is with any 25+ year old engine the majority of the problems associated with it today are from old age and high mileage. The block and major engine components themselves can easily withstand in excess of 300,000 miles.
What is BSFC in engine?
BSFC is the measurement of efficiency of fuel by the engine that combusts the fuel air mixture and produces the rotational motion of the crankshaft. This is used for comparing the efficiency of the engine. BSFC is the ratio of the rate of fuel consumption and the effective power produced from the engine.
What is the bore and stroke of a 460 Ford?

How many miles does a 460 big block last?
Just make sure to keep it tuned regurally and use good oil. I’ve seen 454’s with over 150k still going strong. Big motors like the 460 weren’t meant to go 2-300k, but they can if properly cared for. At 30k you have just broken it in, relax and worry about it when you start getting blue smoke and blow-by.
Why does BSFC increase with engine speed?
The decrease in BSFC is due to the better physical and chemical properties of fuel which assisted in improving combustion at low engine speeds. On the other hand, at high speeds, the friction heat losses occur and combustion deteriorates which increases the BSFC.
