Okay, so here's the deal, I installed a set of BBK Underdrive pulleys on my '84 GT, and removed the A/C and Smog Pump as well. Well, I was down in the garage trying to size up a new belt and I discovered something. Due to the circumference of the bigger water pump pully, the portion of the belt that goes from the water pump pulley to the alternator pulley is at a different angle now, and my stock tensioner barely touches it. There's no way that the stock tensioner is going to be able to work without making it swing a bit lower. My other option is to put the stock water pump pulley back on, but I don't want to do that for obvious reasons. Any ideas or suggestions? Thanks!
