440 problems (take 2)... More known values
I currently run the .528 cam in my 440 and have a 3500 stall with 28" tires. In OD I have a 3.47:1 ratio. The rear axle ratio is 4.56:1.
I used to run a 26" tall tire with 3:73 gears, which with the OD was in the 2.xx range.
I would not change from the 2800 stall, I might even add more.
I agree with Moper in regards to backing off the duration at .050.
