This helps a ton!! I will look at the pics closer when I get to a computer but is the bottom pully two groovs or three? I know later motors had three grooves on the crank pully for smog pump right?
the set up I posted has a three groove crank pulley
two belts run over the crank pulley, the A/C compressor and the alternator (though for some reason the blue engine I posted is only running one)
the third belt runs over the crank pulley, water pump and powersteering pump
there is no idler pulley on this set up, though I think the earlier A/C set ups were different and did include one?
