'67 390 belt & Pulley help By Anthony - 11/03/2002 8:51:39 PM; IP 67.8.51.96 I have a '67 Mustang GTA 390 (no smog or a/c) that I just put power steering in with a ford pump. My original belt configuration was a single belt for the water pump and alternator which ran off of a 3/4" harmonic with a single groove. I bought a 3 groove steel pulley off a guy which he says came off of a 390. The pulley fits over the top of the single groove in the harmonic, which of course makes the diameter of that pulley bigger, which is not bad, I guess, because it will run the alternator and the water pump faster. Ok, here is my real question. How does the power steering pump get driven in this configuration? I can get a belt from the crank pulley direct to the p/s pump, but it will just barely rub on the water pump pulley. The new 3 groove on the crank is only about 1/8" from the water pump pulley. Or do I need to get a 2 groove water pump pulley? Please Help!

This thread, so far...
