79 ford 351 truck motor probably has around 160 HP. 120 lb torque
617.952 turbo diesel motor out of 85 MB has around 125HP and 300 LB torque.
ford trannies would be geared for 3000RPM travel at 70MPH, that would be around the 120 HP mark on the gasser motor, cause the RPM HP peak on that motor is around 4000RPM. the Diesel would just be entering it's sweet spot at 3000RPM so you may be getting approximately the same power at cruise, but you would have less power for passing.
