Re: BBC pulley sizes

On my one owner LS-5/M-22- with A/C it has all the Org. engine pulleys. All the pulley numbers start with " AO " . If you need any pulley Diameters let me know. I also run the 811TX water pump.
P.S. Stock clutch fans & Blades, For the most part never spin over THREE grand.
ALL the big three Ford, Mopar, G.M. big cube High H.P. engines ALL had clutch fans. The MOPAR 426 Hemi GAINED 17 H.P. using a clutch fan. Overdriving the water pump may cause the coolant to be removed from the heat exchanger before it has dropped in temp. The correct fan blade, Moves XXXX number or Cu. Ft. per Min. not only pulls ambient air through the heat exchanger it also removes Super Heated Air from the engine bay.
Super Heated Air will cause problems such as VAPOR LOCK or boiled fuel, High engine Temps Etc,Etc.
