bigger transmission and rearend on a V8 dart.
The maximum speed of the Mercedes Benz 1114 diesel 6cyl 140HP 1972 was 120 km per hour.
The maximum speed of the truck Ford B-600 diesel 6cyl 140HP 1972 is 180km/hr.
The maximum speed of Ford F-600 diesel truck 6cyl 135HP 1972 was 120 km per hour.
170 kph
4 cyl = 196cid 6cyl = 232 cid 6cyl = 258 cid 8cyl = 304 cid 8cyl = 345 cid
112 MPH
If it is 137 MPH then that is what it is. Was it around in 1972 is the teal question.
The maximum speed of a the 1972 Chevrolet C70 truck is 76 mph.
The maximum speed for a 1972 Ford F-600 diesel is approximately 75 mph.
Possibly around 90 mph on a flat smooth road.
I saw 110 mph once in mine, may it rest in peace.
If fuel consumption is not an issue then go for a 6cyl, although on the 4cyl you end up thrashing it due to its lack of power causing fuel consumption to increase dramatically. Having owned both types, the power and torque are definetly noticeable on the 6 and it offers a much smoother and fun drive. Plus if you're planning on going off road, there is no question about it, the 6 offers the low end torque you need. In terms of maintenance costs (other than fuel), there is no real difference. If you go for a 6cyl try and avoid the auto. The auto box on wranglers is very crude and dated and much of the 6cyl performance is lost - go for a manual instead.
