Y'all,

I decided to join the group by posting a thread regarding my Roadrunner restoration project! Hope it's ok. I created a thread a short while back in the Welcome Wagon forum and now that I have actually begun working on her, I decided to share with the class. After reading several similar threads over the past couple of months, I thought it would be cool to follow suit and name mine accordingly, so like Roger and Rusty (to name but a couple), this is "Jerry's Roadrunner" - hah! ;-)

First, a couple of quick caveats if I may. This is my first American muscle car and thus my first mopar. I'm new so cut me some slack if I ask stupid stuff. Also, I have another restoration project already underway, so with a full-time non-automotive work schedule and regular life stuff I expect this restoration effort will require at least 2 years, likely more. There might be dry spells in my posting, but I'll keep things current with my progress. Silence from me only means I'm busier-n-hell, as this project is priority for me.

Ok now to my new prized possession. She's a 1970 true RM23 Roadrunner. I did the online VIN check prior to purchasing and also got a few things from the seller in a rather significant attempt to authenticate her history prior to actually laying down any coin. This was a sight-unseen Internet purchase, so I was apprehensive to say the least. But in the end, she was exactly as advertised, so I can't complain much. On the positive side of things, she has a numbers matching 383 and 4 speed, bucket seats (supposedly from the factory) and a pistol grip shifter. On the not-so-positive side however, the list is large. Overall condition isn't good. No fender tag. No broadcast sheet. Still trying to track down the history. Not much luck thus far. It's sat through at least three owners that I know of. Every panel will need to be touched with many in need of replacement. Too many missing parts to list. Cracked front windshield. Sagging rear suspension. Non-original wheels. And finally, both the engine and tranny will need a complete overhaul, if they are even salvagable.

Hmmmm...what was I thinking again? Hah! Well, it's admittedly not the path I wanted to take with my first muscle car. I had wanted a numbers-matching opportunity, but without the tag or a broadcast sheet, that's gonna be impossible here. So instead, I decided to simply pretend that I was/am living in 69 or 70 and have walked into a Plymouth dealership. I'm sitting down with the salesman who is filling out an order form for me. And I'll build this car like I would have ordered it back in the day. Again, not quite what I wanted, but it is what it is. If anyone can help with the history, I'd be immensely grateful, but I've already contacted a couple of potential Internet resources in that regard and the news wasn't good. My RM23 was manufactured in St. Louis, FWIW. Anyway, maybe the next project can be a numbers-matching affair. Just gonna do the best with what I have.

A few introduction pictures follow. Arrival:

It's difficult to post again on the forum, so I will stop here for now.

Thank you for reading,

And the air grabber has seen better days:

Gonna stop here and pray that this post makes it past the FBBO posting gods.

So this past weekend I finally got around to doing some work on her. Engine stuff is my favorite part of any build/restoration, with bodywork being the least. Boy but is this project gonna be trying at times! :) Being that as it may, the engine needed to be removed anyway, so I decided to begin there. Whoever put the engine in like this was ... well. They just were [fill in the blank with your choice explicitive]:
Nice engine placement.jpg

I had to remove the driver's side head just to get the thing out. Like the remainder of the engine, it's seen better days:

On its way out:

Yeah I'd say this thing has been sitting for a while:

I guess someone decided to keep the push rods as a souveneir:

Nice taping work on this engine spray, huh?

Bottom side didn't look too bad:

Naturally she's stuck solid. I've been spending a couple of nights cleaning and lubricating, as well as attempting to clean the bores. But I digress. I won't really know anything until I take it to the machine shop, so I'm currently reserving judgement at the present time. We'll see.

Anyway, that's where things are. Thank you again for welcoming me to your forum!

Hi Jerry:

Thanks for posting a ton of pictures! I always enjoy seeing a project right from the very start, and since you have the same year as mine, I'll be watching as you progress. Good luck with it.

Welcome to the site - there are a lot of helpful and knowledgeable people willing to help answer your questions on this board. And welcome to the world of "project cars". By the way, IMO the green engine paint has to go.
 
Welcome to the site Jerry. There are several restoration threads on this site. If you go to forums, you will find them. Should help you a lot.
 
Hey Jerry, nice to see some photos of your car. It's amazing what we find under something that looks good on the outside. Don't worry about how long it takes to get your ride looking the way you want it. Mine's been a project 20 years in the making (but don't take that long,ok). The good news is that those year B-bodies have all the replacement parts/panels you need for it. I have to agree, that John Deere green on the engine has got to go. I would find another way to set your hood somewhere (see photo), one bump and it could go down and cause more damage that you don't need/want to repair. Good luck on your car.
 
:sSig_hihihi::sSig_welcometoourcl very nice looking car to start with thanks for posting and keep us up dated on our project I started a post a while back for photos of the 70's feel free to add yours to:blob1:
 
at first I thought the hood was bent backwards lol

great pics , keep em coming
 
Welcome Jerry. I'm excited to watch her come back to life. Looks like you have a good project there. I get overwhelmed sometimes but I just step back and regroup and continue on. Best of luck.

Thats going to be a great ride when your done with it Jerry! i wish you luck getting the old bird back to where it once was, i think you'll find these Mopars very addictive lol, Most of us has found it out i think.. There's something about them that makes us go that extra mile to bring them back to life!
 
Welcome Jerry, That is one green engine! Are you planning on keeping the green on the car? That's an awesome color. Don't let the body work intimidate you, it's just one piece at a time. Looking forward to seeing the progress on this one. If I owned a road runner it would be a 70. Nice lines on that year.
 
Thank you to everyone for the welcome and replies. I appreciate the support from those who have endeavored to begin such a long process. I hope to learn from your experiences.

hunt2elk and roadrunnerman and others - Yeah I wasn't/am not a fan of the green engine color either. From what I was told that was done two or three owners ago, all of whom pretty much let the car just sit around. Judging from the horrible body work (1/2" of filler - REALLY?!) and other obvious evidence it seems clear to me that was indeed the case. But it is what it is and it's mine now so I'll change all of that.

And speaking of engine color, the research I did regarding engines of this timeframe indicated that regardless of the original body color that my RR had (whatever that was), the engine would have been blue. Is that correct? If so, what shade of blue would that have been exactly? Is it like the powder-ish blue that my valve covers currently have?

To answer the question of what I'll do with the body color, I'm not certain yet, but it will likely be this same lime green or the plum crazy purple. Did the green variant have a phrase name like that and if so, what was that phrase name? (plum crazy purple, citrus orange, etc.)

Many thanks!
 
interesting project... the engine color should be Mopar's orange color, not blue, that was a different engine color in different years & body styles....

RESTORATION UPDATE

Progress as of April 19th:

* 383 Disassembled

All parts stored into freezer bags, as per normal. Well, the parts that would fit anyway.

After a week of overnight soaking in lightweight oil, regular oil, WD-40, combinations thereof and finally acetone last night, I decided that it was time for the gloves to come off and the engine to come apart. And tonight was gonna be the night. She had put up a hell of a fight, gotta give her that. I have a couple of observations and a couple of questions.

As I mentioned, she was stuck solid. To get it apart, I removed the mains and all of the rod caps that I could get to. I couldn't turn the crank, but with only a couple of rod caps remaining, I could free the crank vertically enough to allow it to turn just a bit. Worked that back and forth, got to the final two nuts, removed those caps and did something I really don't like doing: I pulled the crank up and out of the block. The rods do articulate and get out of your way for the most part, but I still don't like doing that. But you don't have much choice in these cases. Then I had 7 remaining pistons to remove (was able to get one out with the crank still installed). With the significant amount of rust and other crud in the bores, they just weren't gonna go easy into the night. So I did something else I don't like doing: I decided to sacrifice the pistons and in most cases the walls too. Turned her upside down, used a bar and hammer-shocked them out of their respective cylinders. It works but it's just "nasty". But whichever. Gotta do what ya gotta do.

The bores measured out at 4.25 which tells me that they haven't been mucked with yet. Is that correct? My 383 has hydraulic lifters. Was that standard in these engines in 70? What do the oil pump gear clearances look like? I don't know much about Mopars, but these sure felt loose to me.

Hmmmmmmm...seems like I had more questions, but they escape me now. Maybe later. ;-)

Pictures follow. Thank you for reading.
