Ken,
I'm running 39.5" Supper Swampers, with the 5.83's (behind my V-8) on the M37. I've easily hit 70 MPH, but I'm not recommending that kind of speed with the old suspension and steering.
The 39.5" SS's give me a 12% increase in speed. you would see about a 5 MPH increase to 50 MPH.
The 4.89's with stock tires would give you about a 19% or about a 8 MPH increase to 53 MPH.
