I am leery of messing with the cam - the motor was strictly truck/van and in stock form was rated at 245/330 (nearly identical to the 1974 360 4bbl and slightly hotter than the 1973 340 4bbl). I have to imagine they installed it according to factory specs but it would probably be worth checking. There is not a ton of info out there on these motors so I don't know how forgiving that grind will be if I start tinkering with it...
