I have covered about 500km since getting the car drivable in October of 1996. One thing is sure - it ain't no "B" anymore!!! Needless to say, I am thrilled with my machine and cannot wait for next spring to arrive. The car has a 2-1/4" single exhaust pipe system, no muffler, but has two custom made resonators at the rear ending up and exiting through a double chrome tip. She is very throaty and sounds like Steve McQueen's Boss Mustang in the movie "Bullitt". She revs at 2300 rpm at 60mph in fifth with the 3.25:1 differential. The Ford Posi is really tight and I have to keep adding friction modifier. Since the car is still "running-in" I have not pushed her hard yet. I have installed a manual switch for the cooling fans and also wired in a security kill switch a la Roger Williams' book (How to Give Your MGB V8 Power). I intend to install Fiero seats over the winter and also change the front coil springs. I have a new pair of GT coils installed and the car is too high at the front. I am going to try a pair of used 1972 chrome bumper coils and see if I can get it down an inch.
