What spark plugs?? squeaking belt
 

I had autolite 764,s in and pulled them out and they where white, I have heard that means too hot of a plug?? and what causes belts to squeak , it looks like the belt is in good shape. the only thing I noticed is I can move the belt tensioner a little. My mods are in the sig. thanks

Try some NGK heat range 7 plugs. It sounds like you are running lean to me if I were you I would go to the dyno so you could get an accurate reading on your air to fuel mixture.

thanks, it feels like my car is running rich, but it could be lean. I have the fuel presure unit that came with the blower, can that be adjusted wrong causing it to run lean/rich??
