Close enough Gerry, there were 5. A base 88 HP 2.3 L 4, the Turbo 4, the 3.3 L in-line 6, a 2.8 L V6 and the 2 barrel 302 that pumped out a Ground Shaking 140 HP ?
Your question Sir ?
So technically you were correct, although there were 2, 2.3 4’s, NA and Turbo
Another WAG. The mustang had a longer wheel base, and the front axle was farther forward. The front would have been the a=easiest part of the car to modify.
