Hey Gang! Long time no see. My 96 chevy 6.5 bit the bullet so I am back to driving my 92 F-250 7.3 5sp 2wd.
Above about 40 MPH the speedometer jumps from whatever speed i'm driving back about 10-15 MPH less. Any Ideas? Truck has about 400K on it.
I had forgotten what a simple and efficient design the old 7.3's were. Wish they were still being made.
My Best,
Justin
