67 289 AC belt/pulley dilemna. :shrug:

Here is the situation:

67 FB with 289 and stock A/C. It's a California car, so it had a Smog pump in the mix and belt runs to it. It goes Crank/ AC/ Smog pump. I want to toss this Smog pump that's noisy, worn out, useless and an eyesore, but it appears that I could not run a belt directly from the crank to the AC if I tried.

I'd like to run it through the water pump (that is if it had 3 grooves in it). The water pump pulley only has 2 grooves.

What to do?

Is there out there a water pump pulley with 3 grooves? NPD does not know...

PAW used to sell the 3 groove pulleys. Can you tension the belt with the A/C compressor ? Or does it use the smog pump for this ? The non smog cars used the idler pulley on the A/C bracket (driver's side of engine) to tension the belt.

This might be the ticket, as I"m sure there's no adjustment on the AC pump side. The Smog pump used to be the one that tensionned the belt.
