225 Slant six Needed near NJ

I live in NJ, I have a 1974 Dodge Dart Swinger with a dead 225 slant six, automatic. It died on me last year while driving on the highway. I heard a lound thumping and the car wouldnt drive forward or back. A mechanic told me I would have to get it rebuilt or swap it with another.

So im looking for a quick swap to get it driving again soon because I miss my baby.

Looking for 225 Slant six complete rebuilt or well maintained.
Looking for Transmission as well. I have a automatic but either automatic or manual will be good.

You have to be Near NJ!!
