Swapping Heads On A 1974 Mustang II

rickdavid · 09-11-2007

Hi There.

I am new to the site. My first question is in regards to a 1974 Mustang II 2800 V6. 5 years ago my daughter overheated the car and cracked the heads. It has been garaged ever since and now is the time to get it back on the road. Recently I have stripped out a 1977-79 Mustang II with a 2800 engine. I was wondering if the heads are interchangeable. The newer motor has more pollution devices, different intake and slightly different exhaust manifolds and missing carb. I had put on a new carb just before the heads went. I would like to use the original block if possible.

Any help would be greatly appreciated.
Regards
Rick

It should all change over, there weren't any serious design differences to the Lima engines until 1979 or 1980 when the 2.9L version came out for the Bronco II, Ranger, and Aerostar. Same basic achitecture survives today in the 3.0L V6 in the Ranger, and to a lesser extent in the 4.0L SOHC V6 in the new Mustang, Ranger, and Explorer.

Thanks, I have gasket set and the block looks pretty much the same, the only thing I wondered about is the 1 inch or so piping that comes out of each exhaust manifold and crosses over on the 1974, Can I disconnect and plug these holes.
