I don't wuite understand your wuestion. The 302 is a stroked 289 if my memory serves me. The 289 has a 4 inch bore and a 2.87 inch stroke. The 302 has a 4 inch bore and a 3 inch stroke.
The Engine for my 67 Mustang has the following specs. The Cougar would have had th same engine back in 1967. The C4 will fit either so it should not be a big deal.
