Which groove in the crank pulley did you use to turn the Alternator? Did you use the groove closed to the harmonic balancer to turn your P/S? I have the long water pump set up with a triple groove crank pulley.
Thanks for the help.

I can't answer "why" but it seems that every long waterpump BBC crank pulley I've seen has 3 grooves. The outer groove (away from balancer) is for alternator and the center groove for PS- the innner-most groove right against balancer I assume was probably for an AIR pump.

Survey says: front groove.
The belt isn't actually on the engine in this picture but you can see the power steering belt goes in the rear groove on the upper pulley. The rear groove in the bottom pulley doesn't line up to anything unless you have an A/C compressor. I like this setup because if you throw the alternator belt your fan keeps running.

I have a long water pump and a 2 groove crank pulley the PS belt went to the inside one and the alt went to the outside one. You can kinda see it in the pic.

The 3 groove is for cars with AC too. AC car's PS pumps have 2 grooves, and the rear crank groove goes around inner PS pump groove and the AC compressor.
