Some basic fab skills and this GM part# 10085753 will get you a dedicated crank drive.You have to pin your crank to the blower drive pulley.By this I mean key the pulley/pulleys to the crank snout or you will spin the drive off in due time especially if you plan on spinning the blower relatively hard.

 

Where did you find that? What's the diameter?

 

7.5" or 7.625 not sure but,the pulley comes on 96-00 vortec 350's.

 

thanks for help members. I'll check with whipple to see if they have this crank pulley.

 

Where can i buy the crank pulley for the same set up? i contacted whipple and they dont carry it any more.

Thank you
