Examples:
If an unrestricted 360 makes 700 HP and has a BSFC (lbs/hp/hr) measured on the dyno of 1.1 at peak power and runs a 10 minute feature without stops it will consume less than (1.1 * 700 / 60) * 10 min / 6.6 lb/gal = 19.4 gals.
If 410 makes 850 HP and has a BSFC (lbs/hp/hr) measured on the dyno of 1.1 at peak power and runs a 10 minute feature without stops it will consume less than (1.1 * 850 / 60) * 10 min / 6.6 lb/gal = 23.6 gals.
The reason it will consume less than these numbers is because non-wing cars let off the throttle going into the corners. A wing car will be different depending on the track because they don't tend to let off the throttle as much.
Do the math for heat races, etc...
I hope this helps,

360 motor on a half mile, 25 lap feature running green to checkered with 2-3 laps for alignment and 4-abreast... should equal about 21-24 gal. of fuel.

Is it a wing car?
So either it's a 750HP engine running at 1.1 BSFC or a 700HP engine running at 1.2 BSFC.

Ted... I based that on a wing car that ran with us at West Liberty IA. (1/2 mile) last week.
He had a bad heat race and had to run the 12 lap B.
They started 17th in the A main and came throught the field to win.
When we were there a year ago... the track was extremely heavy and rough.
With a few reds and a couple of yellows.. we were concerned about fuel. The top 3 cars finished on fumes.
