junkyardwarrior, the idea is to build an engine that runs on ALL cylinders! No doubt the loss of a cylinder really hurts on a 4-cylinder. For those who knock carbs and points, remember, all cars prior to the mid-1970's had points. Corvette's, Cobra's, Mustangs, GTO's (please don't call them a goat, that is for Dodge Rams) and even race cars used them, and they ran great. YES, YES, YES, electronics are far better for today's engines that have Fuel-Injection, o2 sensors, MAS, MAP, Vacuum, TPS and even more sensors, and rev high RPM. But it is not necessary for engines below 5,000 RPM with a carb. Maybe today's motor-heads just don't understand carburetors and how to adjust them. Once I adjust a carb I do not need to readjust it for many thousands of miles. The same holds true for points. Today's points are far better than OEM 1965 points and so are coils, wires, and spark plugs. And I do run a Pertronix after setting the dizzy for points, then keep them in the glove box or trunk. For my younger car friends...TODAY'S ENGINES ARE FAR BETTER THAN 50 YEAR OLD ENGINES IN EVERY RESPECT! However, my 6-cylinder 1965 Mustang with automatic, air conditioning and front discs gets 25 MPG while running the AC at 75 MPH...and it will go well past the century mark, though I have not had an opportunity to check MPG at that speed.
