i remember a guy had one in a 70s truck, this is at a Ford dealer I worked, they tried tuning that thing up, his complaint was "its a dog" I forget did they have the VV carb on them? anyway they threw a whole tuneup at it and the guy who owned it said it "ran the same" i dont know if they bumped timing checked timing chain slack etc. but ...yeah. i do remember they were in the big station wagons also. The 70s cars were wierd, big cubes but low HP. Then in the 80s Ford got back on track with the 5.0 Fuel injection setup. The stock fox body is 200-225 HP but man they run and are dependable.
