Belt Length Can some one check me on this and tell me if my thinking is right? With a 3.4" pulley I needed a 51.5" belt. Now I am changing to a 3.7" pulley. The circumfrerence of the 3.4" pulley is 10.676" and the 3.7" is 11.618". So do I need to find a belt that is 52.5" to make up for the 1" larger pulley? Or will a 52 be big enough since the belt does not ride around the whole blower pulley?

Hey Chris, for the 7.25 sdce crank pulley and the 3.7 you can get a Napa #080525 - 53 1/8. Napa has good durability and grip.
