Pulley ??

I have a buddy putting a 400 in a '67 Dart right now. I tossed him a SB 4 groove crank pulley and he found a SB 2 groove water pump pulley and with a 1/4" spacer he got them to line up. But it seemed like he was going to have to build a custom alt mount to get everything done. And because of how close his aluminum radiator ends up, he can't get the fan bolts out without removing the radiator. I told him to use the single groove crank pulley I had and order the water pump pulley from 440Source and be done with it. Too much futzing around when the parts are available.

There was a similar setup on 67 or 68 Dart at the Spokane Speed and Custom show a couple of weeks ago. 4 groove crank pulley with a 2 groove water pump pulley and 3 spacers to get the alt to line up. No idea where he got the water pump pulley, but I would bet it was a SB one.
