My son and I are working on the 66 coupe that he bought for $250.00 in 1980 while he was in H.S. We have put a 4.6 four cam 32 valve aluminum engine from an 03 Mach 1 in the car. We also put in the 5 speed trans from the 03 and the black leather seats. We also designed a fiberglass hood that has the shaker set up. The car is the original gold color and will have a black stripe when completed. All that stops it from being finished is money.
I now drive an 03 Mach 1. Great car except in winter. It hates snow.
Why celebrate the Mustang, the first actual “Pony car” was the 1962 Studebaker Avanti, long hood, short deck, bucket seats, 289 V-8 like the Mustang, but could be ordered with a supercharger. Studebaker was far ahead of its time! A far more beautiful design IMHO.
