I have a 200 I6 that originally came with a 2 groove pulley, I can get a 3 groove pulley for about 100 bucks. My question is, is the 3 groove compatible with the motor that came with a 2 groove. Its and 81 that originally had a/c. A/c is gone, all i have is p/s, alt., water pump, and smog pump. Can I put it on there and just leave the one groove unused?
