Hi guys, I'm new to your forum, I am from New Zealand and I'm after some information. Some years ago I fitted a 3.8v6 into a ford Cortina, the engine was out of either a mustang or cougar and had been rebuilt for a race car, it has a carbi fitted but I'm looking at converting it to TBi or port injection and I'd like to know if the manifolds from the later versions will bolt into my engine or is there something preventing this? such as different cylinder heads.
