I know that it is physically bigger than the standard core. I'm not sure but I "think" you can cut the standard heater housing to fit the larger core.

1973/79 F100/350 & 1978/79 Bronco: There are three different heater cores, they do not interchange.
1) Factory installed integral A/C (A/C controls in same panel as heater controls) / Same core as Hi/Lo Comfort Vent System.
2) High Output heater.
3) Heater only or with Deluxe or Economy dealer installed A/C.

Don't try the high output heater if you are not sure. As others have said they are not interchangeable. I looked at the two at autozone and the lines coming off both units are different as well.

I just had a thought, before you order, look under your hood. See if you have a big evaporator housing, like the fact A/C trucks have. Ford had a not too common option called "Hi-Lo Comfortvent" system. This was essentially the Factory A/C system without the A/C part. I believe this was a 78-79 option only. If you have this, order the heater core for an A/C equipped truck.
