not that it matters but:

The previously optional 289 c.i. 225hp V-8 was replaced by a 302 c.i.
version rated at 230 hp. Increased displacement was achieved by
increasing the stroke of the 289 from 2.87 inches to 3.00 inches. The 2
barrel carburetor 289 (rated at 195 hp for 1968) was replaced mid-year
by a 2 barrel 302 rated at 210 hp. Thus both 289 and 302 V-8 powered
Mustangs were available in 1968.

1968
C code 289 2v
F code 302 2v
J code 302 4v
