will a sbc crank pulley mount up to a bbc

NO it may bolt on but need s to center off the small step on the pulley. the BBC damper ID is a bigger on the pulley small step . ID on the SBC step on the pulley is smaller so the part that center s on pulley is a step that just fits in the crank damper ID with out this the pulley centers off the 3 damper bolts if a steel stamp pulley the center will crack out and come flying off i know this first hand . if a long nose water pump. pulleys will not line up to any thing BBC

thanks... appreciate your info. you don't know were i can pick up a underdrive pulley for a reasonable price for the crank on a bbc. im having radiator hose conflicts.

FOR WHAT WATER PUMP SHORT OR LONG THEY TAKE DIFF PULLEYS .can you move your hose or make up a steel tube then use rubber on the ends for engine flex

long water pump..... messed around with the way the radiator is mounted, and i think i can make a hose work now. going to the parts place tonight.
