....yeah, your going to need some sort of trick/tricks to win. An engine is just an air pump. The more air/fuel that goes into the cylinders, the more power that is produced. An a 400 cu in motor is a bigger air pump than a 327 cu in motor. A LOT bigger motor. Thats why they seperate some drag race classes by the motor size. ALL being equal, that is weight, traction, etc, etc, etc... He's is going to eat your lunch because of the 'fixed budget'. Now, on the other hand, if you put $20 g's into your engine & he puts $3 g's into his, it could be a different outcome. Plus 3 g's isn't much money to work with for either of you. And seeing as how your building a high RPM motor your going to have to use TOP quality parts if you want your motor to last. Example; he can get away with a cast crank, your's is going to need to be forged..... Either make him another bet where you KNOW that your right & then you'll be one for one on your 2 bets or cheat on this one...... zzz
