I have a 1971 Mach 1 mustang with the 351 c.i. V-8 2V Engine . What can I do to get more horsepower out of it with out buying another engine .
Sweet car- get a 4 barrel carb- Summit should have one- they can even jet it for you- that is a good engine, you don't need to change it out, just a 4 barrel, headers, and electronic ignition will work wonders-
