JUSTIN Posted June 18, 2001 Share Posted June 18, 2001 65 riv with a 401 rebuilt engine of unknown source. the car runs like a $40 mule (thats real good for you youngsters out there). If I have the timing at 4 degrees, then it will jerk your head everytime you touch the gas. so I keep it retarded just below TDC. Idles smoothly also. gets about 10-12 mpg in town. regular gas. eldebrock carb. all stock.<P>My question is: Is the way all 401s run, or do I have a super engine? If this is the way the 401s run then this is the best engine in the world. why would you add any performance parts unless you dont want a street machine.
