Little engines that can

[RichSchmidt]

You have to look at the entire car. The top guys have drive train parts that are built like a violin. They rollerize everything,machine every last part until it is the minimum size or thickness needed to do the job. They will run a rear end with a cupful of zero weight motor oil in it,the same for manual transmissions. You could probably walk up to an engine less manual trans stocker on jack stands and spin the input shaft of the trans with one hand and watch the wheels turn. Spin it hard enough,and the wheels will probably keep turning for a while. Everything is butterly smooth.

Over on hardcore5.0.com, there's a 93 Mustang GT, street car, absolutely stock untouched shortblock, H/C/I car that runs 10.50's N/A. Optimal efficiency is vastly under-appreciated.
