For a while, I have had a 91 Mustang sitting around with no engine or tranny. I was originally going to go with the 5.0 engine, but I have started coming around to the Modular engines. I found a guy who has a wrecked 96 Mercury Cougar with the 4.6L in it, and I was wondering if getting this whole car for $500 was a good deal. This would get me the engine, tranny, and computer for the car, and I'm wondering if it is worth my time... I was also thinking of trying to get this car and doing carb+intake path, but then I thought that would keep the transmission from working... I don't know much about the aode's but some help would be nice.
