[Shotimes] Daytona 500 & NASCAR HP

[av8r567@optonline.net]

My 1400-lb airplane cruises at 200+mph with an 74 cu. in engine that puts out 74-hp and 78 lb-ft both at 5000rpm.  It also sips 5.7 gals/hr of 100 octane Low-Lead avgas.  NJ to Florida in 6 hrs NON-stop - you can't do that in a Z06 or Nascrap car.
