Serpentine conversion

Hello guys! I have a 1987 iroc with a 305! I currently converting to serpentine belt system. The crank, and water pump pulley aren't in the best of shape! My question is will the pulleys from a obs truck work on my car? If not maybe you guys can lead me in the direction to purchase those pulleys! TIA

Re: Serpentine conversion

88-95 should be the same. Vortec pulleys will be different.

Re: Serpentine conversion

Depends on which serpentine brackets you're using.
f-body and b-body (i think) are the same
truck and corvette are both different from each other and the F-bodys.
Have to keep the systems the same because pulley offset is different

Re: Serpentine conversion

I got the whole set up from a 1992 camaro! The waterpump, and crank pulley look rough! Imma try to clean them up with a wire wheel! Hopefully they will clean up ! Thanks for the info
