[QUOTE=Singleton;6348546]Typically, Pontiac had their non-A/C engines underdriven by 8 to 15%.(water pump driven at 85-92% of crank speed).
Agreed, however Pontiac engineers weren't dealing with todays higher hp applications and performance standards. Also today's fuels don't provide the cooling and lubrication affect of the 60s and 70s.
