To sum it all up the "Horsing around with the mustang six" article has shown everyone that you can achieve 125 at the wheels without to much serious work and run 110mph @ 16sec with 4:1 gearing, which by the way is equal to todays stock Mustang GT with the SOHC 4.6 V-8 which I believe puts out around 180 at the wheels but obviously it's a much heavier car.
Now if someone was to take it another step and enlarge the valves some porting, polishing maybe a more aggresive cam, upgrade the valve train you might get another 20 or 30 and throw on a super charger or turbo and you could make over 200 and at the wheels and out run most anything you come across on the street.
I can't wait to get my car back up and running, tuned and dynoed. The first thing I will do is post the results.
