I have 67 ss that i bouhgt w ith the engine out. It came with chrome long water pump that i would like to use. Looking for chrome single groove drive(no PS) manufactruers. Will I have any clearance problems with radiator? Can I run my alt. on the drivers side?. Can I use a four core. I saw some chrome pulley's in Jegs and Summit but they were all 3 groovers for crank and two for water. Again I thought there may be clearance issues with these multigroove pulleys.
thanks, Tom

Do some searches here and you will find that '67 w/BBC needs a SWP, and three grooves on the crank if you have PS. I have this setup with a 4 row rad.

If I were you I would get a swp before going any further. You will have problems with the lwp. JMHO:yes:
