    Hello all again, we just set up an account here but I have been on FBBO for several years in case you missed the welcome wagon post. I'm known as Runner 68 over there.

    My 16 year old son who just acquired a 1972 Duster and this will be the build thread. I have been around the B bodies and E bodies for roughly 40 years but am pretty green with the A bodies so we're looking for that great assistance here that I get over on FBBO.

    I'm pretty excited to get into this project with him and he is as well. I think it's pretty cool that a guy of his generation has chosen to get into this hobby. He thinks it will be cool to have 2 old Plymouths sitting in the shop. For what it's worth he had an opportunity at a big block Chally but chose the Duster.

    So here it is, 1972 Base model, 318 / 3 speed on the floor. ~80K miles. He purchased it from a family member for $1,200. It was put out to pasture in 1993 in dry Colorado but ran fine when it was parked.
    We went out two weeks ago and filled it full of PB blaster and Marvel and let it soak for 2 weeks.

    We got it home into the shop this weekend and started the clean up. The first order of business was to roll the engine buy hand. We pulled the distributor and tried to prime the oil pump with a drill, got a little pressure but it never made it up to the valve train. Rolled it over a little by hand to get the journals opened up and tried to prime again....nothing to the top.

    It rolled over very smooth from the start, nothing stuck at all, which surprised us but good news none the less. I am however curious why I didn't get pressure to the top end.

    My thoughts are 1. The Marvel is too thin to pressurize up top. 2. The pickup tube is gunked up and can't pick up.

    Next weekend's plan is to drain the Marvel and drop the pan, replace the oil pump, pick up and work from there with real oil
    We're taking it one step at a time through all the systems to get it to fire without dumping too many $$ into it. If that fails and we need to build a new engine, so be it.
    Thoughts are welcome, pics below.

          Yes sir, that's why we grabbed it. Unfortunately my 68 Runner gets put on the back burner yet again. :thumbsup:

          Looks to be all there which is a great start. Enjoy the time with your son on the project as time goes by us too fast.

                Ha-Ha, thanks for sharing that. It even has surface rust in the same spots. My son would kill to dump a big block in his. In due time, in due time.

                  Looks like a great start for him. My son has been on and off then on again with our Duster. He finds his own projects then disappears for a while but he loves the car and comes back to join in. As I'm sure has been with all things in his life, your stuff goes on the back burner while you help or do for him. That's your job as the dad.
                  Enjoy the car and the time with your son.

                    I came home from work today and expected to find him in front of a video game after school. I had lined him out with several tasks he could do on his own to the car over the weekend.

                    I couldn't find him in the house so I started walking out to the shop. I got half way there and heard Metallica booming on the shop stereo. I turned around and came back to the house.

                    I think I found the cure.

                      On your oiling issue, there is two places on rotating the crank that oils the top end.
                      If you are only getting oil to one side, the crank needs rotated to oil the other side.

                        Thanks for the the input. That confirms what I figured to a degree. Will let you guys know after this weekend's exercise.

                        You have way too much stuff in your pasture LOL. What's that "red thing" all balled up back there?

                        Actually, (no shit) I think it's a late 90's Ram 1500 that was rear ended by a semi doing 70 mph with my 80 year old aunt driving it. She was pretty hammered up but came out of it OK in the long run. Again, No Shit.

                        We call that part of the property the "warehouse". The warehouse covers 80 acres. Many vehicles with many stories that would probably blow most fellas minds from back east. Being from Idaho you know the drill.

                        I actually could use the passenger door from that for my 3/4 ton.

                        cool history.

                        be careful of the windshield washer tank.
                        I take them off while working on the car
                        seem to be brittle around here.

                          Thanks, yea, it's on the replace list. Most of the plastic on this is extremely brittle.

                          Hell, that would put you in Wray / Holyoke country. I was born and raised in Sterling.
                          Depending on how old you are I may know you. Will send a PM.

                          Good day today. Pulled the oil pan without too much trouble. Had to pull the steering cross link out and cut the factory exhaust out. The pan came out fine without lifting the engine. I'm sure it was because the forward crank lobes were tucked up. Note to self to have them there when we re-install the pan.

                          New rear main seal,oil pump and pick up. The bottom end was very clean. I'm sure the 2 week soak in Marvel had something to do with it. The pan is all cleaned up and freshly painted. We'll pop it on tomorrow. It all went relatively smooth in my opinion. Lemon Jr. learned volumes.

                          We'll go through cooling, fuel and ignition next before a start attempt.

                          One question. Since we had to cut the exhaust out, any damage in a short test fire though straight manifolds when we get to that point? I have never fired an engine with only the stock manifolds in place. With headers, several times.

                          We would rather not bolt the stubs of exhaust back up unless we have to. It was a bitch to get out in the first place. Headers will go in eventually.

                          Opinions are welcome as always.

                          Nice Duster.

                          Don't let that Ram go without considering pulling the engine and electronics for a potential FI Magnum swap into the Duster, especially if it is a 360.

                            A run with open manifolds wont hurt it.
                            If you are going to try moving it, then bolt the stubs on.

                            Redneck road test: open headers and no hood. Mandatory in my shop. Usually just before sunset.

                              Looking at the engine ,looks like a runner. Still has the beloved wire hose clamps. Never cared for those.

                                Subscribed. My first car 40 years ago was a 71 Duster just like that. 318 with no power steering, brakes and a manual transmission will keep your son busy driving instead of being distracted by his phone and friends. Let us know what else you need and we'll be here to answer your questions. Good luck to you both!
