Mr Finland the c code and j code pumps are the same except the j code has the fuel screw turned up more with more timeing.the stock c code 6.2 made 130hp/240tq the military j code 6.2 in the cucv trucks made 165hp/330tq if you want these numbers you will have to get a j code intake without the egr advance the timeing a few degrees and turn the fuel screw up 1/4 turn to get more power and get rid of the factor intake tube with a good exhaust and more fuel should get you around stock 6.5 power.and if you haven’t already get the injectors rebuild with the pump
