Just a tought ?

Thinking of putting a gearvendor overdrive behind the A-727.

Just thinking what that drop in rpm would have on the waterpump rpm and cooling issue?

Have had none until now.

Any thougts are welcom.

ok.....back to gear vendors......it doesn't kick in till 30 mph.......rpm drop is around 600 to 800......i dont have any cooling problems and i dont have any under drive pulleys either.....i have a dimmer switch to activate it.....i think its worth the money for cruising and drag racing....both worlds....easy to install with directions....you will have to shorten your driveshaft

The RPM drop will actually work in your favor. Lower RPM the coolant has time to sit in the radiator and cool with all the air rushing past it actually will cool better.
