My step son recently purchased one of these. A two door hardtop, with a 383. He is a literal neophyte in the religion of Chrysler/Plymouth/Mopar, and the car predates him by over a decade, as well. Since this is a forum full of individuals of advanced ag......er......learning and understanding, I though I'd ask and see if anybody knew of a good website, he might peruse for information, and help.

Thanks in advance, for any help and info.

He said once he figured out it had a choke, it has worked pretty well . It shifts kind of funky until its warmed up, but otherwise runs good. He said it used about a quart of oil, when running for 2 1/2 hours on the highway, at speeds of 80mph, and gets about 12mpg. He says it is in really good stock condition. I recommended 10-40 oil, any additional thoughts on that?

383 mopar! Throw a double pumper 4 bbl on it ...get rid of that stocker. Change the fluid and filter in that 727 and get out on the circuit Saturday night with that sleeper!


Heres a lot of odds n ends...

I speak Mopar. I've had and built quite a few of 'em. I have a 1970 Plymouth GTX sitting in the driveway.
I would run whatever oil the PO used if you can find out. Those old motors didn't like changing oil types very much. They would start using oil a lot of times after changing brands and weights.

I have some 383 HP parts. Shoot me a PM if I can be of help.

Tell him to hop on over the forbbodiesonly.com

Decent bunch of guys over there.

I don't think he's much on the hot rodding and performance end. He is more impressed with the car as it sits. The simplicity overwhelms him I suggested swapping out the ignition for the electronic upgrade stuff. If he gets that done in the next year or so I'll be surprised.
He's clueless on what oil was in it before. It has about 50k miles on it, and he said the oil in it was black. I wasn't sure if the 383's used a bit of oil or not. Do you have any idea what weight was recommended by Plymouth at the time? He has ordered a couple of CD's with the service manuals, so he may see something in there.

Thanks to you other guys for the links. Much appreciated.

I mentioned the fluid change today BR

That's a good looking year. Between my Dad and I we had 12 Chryslers at the same time at one point. I still have a '68 Newport convertible with a 383. It's a good powerful engine that's also not too bad on maintenance. Tell him to try letting it warm up a little with the transmission in neutral, that may take care of the slipping. If this is his first older car, tell him to watch the temperature. I always had little issues with thermostats, hoses and radiators that we rarely see on new cars anymore. My Chryslers also liked to burn a little oil around the valve covers. New gaskets and tightening to spec might take care of that.
