Because the wing car will most likely be on the floor. From flag to flag.

mscs is about right, we usually went through 10 to 15 gal. in our winged 305, these legal motors are about 1/2 the HP (10.5 t0 1. comp/ratio) of a 410 with the much higher comp., similar to highway, car weight, gearing and driver technique affect fuel consumption and ultimately, track performance (the usual racing priority).

Most of the 305 in the southwest use injectors. We would go through about 20-25 gallons per night. (Hot laps, heat races, 30 lap feature) Im not the expert on the difference in fuel usage however, those motors would only turn about 7000 rpm consistently. Also, because they are so limited on power, you had to be spot on with your main jets, high speed and barrel valve. Being fat on fuel had an exponentially bad effect on the 305 (stumbles on starts and low top rpm). Just some info for you all to digest.
