Thank you for using just answer.
Federally mandated side marker lights and a revised grille distinguished the 1968 Mustang from the '67 on the outside, while a slew of new engines set it apart mechanically. A low-performance 195-horsepower 289 V8 was still an option, but the other 289s were gone in favor of two new 302-cubic-inch (4.9-liter) versions of the small block V8. The two-barrel 302 made 220 horsepower, while the four-barrel-equipped version put out 230 horsepower.
Thank you so very much.. I was told that the first 302 was introduced in 1966. Your answer was very helpful.. This answer also settled a bet..
