So I am kinda new here, but definatley not new to cougars. I recieved my first one when i was 15. soon after, i shipped off with the navy, and now 9 years later, i am now getting to be able to start my work. I've wondered why for years why the cleavland motor was in the car when it was vin'd with a windsor. I know the cleveland didn't even come out until the 70's so thats wierd. I've heard of ford throwing in "leftovers" into mustangs, but in this case, it wouldn't be a leftover engine, rather a newer one. Anywho, i know for a fact that this hasn't been swaped in, because of all the markings and its completeness, along with the fact that i purchased it from the original owner who is in my direct blood line. Anyways, does anyone know something i don't, or am i lost. Its a 2v cleveland, and the serial is a late 69 model. I will get the clevelands production date when i get home.
