Its home, the mechanic didn't do a damn thing, claimed this and that - though he did lube the sticking door latch and removed the AC belt, but it ran just as ****ty as it did when we gave him the keys, it dies out and coughs/sputters/surges under load (in gear) low RPMs, If I slap it into drive and gun it after the transmission engages the gear it runs great - at least compared to not going at all. Tanks first, then lines/filters engine ignition, then if no results it might be carburetor time.
Wow, this might actually be simple: it sounds like a textbook case of a serious vacuum leak! Hook up a vacuum gauge & start the engine...if the needle jumps all over the dial (and I suspect it will), you have a leak. If someone removed the carb at some point, it's even money if they cracked it during reassembly, which will cause a vacuum leak.
Also, B/RB Mopars have a little-known design quirk that can make you rip your hair out. Did it sit for a while, and does it...
...run hot on the highway?
...get about 2MPG?
...turn the exhaust manifolds cherry red?
...have weak power?
If so, the distributor advance might be stuck. If so, careful application of a heat gun and penetrating oil will usually free it.
