I have a 68 m36a2 with a n/a hercules in it.I havent driven it real far but when I have takes it out I can get about 50 mph and thats it.The injection pump is from a turbo but all else seems to be fine,It has all fluids and filters changed and runs very smooth,just seems to have nothing in the top end.Could the turbo injection pump be the problem? thanks guys
