Low speed overheat

[Ralph Close]

I have a stock '72 400ci in a '66 Satellite. I wish to speed up the water pump by changing the pulley ratio. The crank pulley is 7" dia. and the w/p pulley is 6 1/2" dia. I want to decrease w/p dia or increase c/s pulley dia. (2 groove) Advice please.

Welcome to FBBO

Maybe post this in another one of the man forums
like the general discussion or any other related forums

this is the welcome wagon not really intended as a Q&A tech section

maybe contact March Industries, or some other pulley mfgr directly
they make underdrive & overdrive alum pulleys

Welcome.

Have you checked the other parts of the system (fan clutch if you have it, shroud, radiator etc...). Those might make a difference for low speed cooling.

X2. The shroud was the most effective for my car. Then a big mechanical fan.
