I am looking at buying a '75 Granada and 4.6L with auto trans and need some help identifying which ECM is compatible with the engine. The guy is claiming it's out of a '95 Lincoln Town Car but does not have the ECM for it. I am wanting to use a Mustang ECM in hopes of getting better performance out of it. I can get engine and trans numbers if that would help. I want to drop in the 4.6L in place of the 250 I6 that the car currently has because I believe I will get better performance and gas mileage along with pass emissions easier. Any suggestions or advice will be greatly appreciated.
