What size belt would you use if you had a 6lb lower crank pulley system and a 3.20 upper pulley? What about a 4lb lower crank pulley and a 3.20 upper pulley? Terry, got any suggestions? Thanks
tiny tiny bit of dust in there, may be from old belt with stock upper. it was a 79 inch and was too loose. i should be making a shit load of power, waiting on my exaust and free accufab tb to dyno it
