Yea, NASCAR, state of the art racing... NOT! Guess we all better dump the
fuel injection, get the carbs back out, and disconnect the computer! NASCAR
runs pushrod motors 'cause the rules say 'ya have to...
Oh yea, speaking of "pushrod" race motors, remember that at Indy (back when
it was real racing not the IRL crap) there was a displacement premium for
pushrod motors 'cause they were at a disadvantage compared to their OHC
counterparts...

Just ask the guys in NASCAR Winston Cup what they think of their "wussy
little pushrod engines" vs. Cammed engines found in say F1 (15K rpm) or even
CART. Bet they'd take the torque over carpal tunnel syndrome from fanning
the gearbox!
