FIRST: Yes, I know this is a Mopar and is off-topic. But, I am a member of this community and don't know any real mopar heads nor am I a member (yet) of any mopar sites. I primarily "restore" Cruisers - but about six years ago I ran into this, was smitten and so I thought I'd share with you what I have been up to in addition to FJ's and BJ's.
I had just brought her home (Mrs. Maddox was NOT happy) - previous owner used CHEAP primer which hid bondo over 1/2" thick!!!!!!!!!!

That is exactly what I said.....what the heck is it? Notice the cowling was cut in half.
Good news - it is a really rare 1970 Plymouth RoadRunner, complete numbers matching.
383, air grabber hood, rare citron poly mist color, 4 speed pistol grip, and all the cool fixins.

It was for sale BECAUSE the current owner:

1. Destroyed the restoration process. There were parts, bolts, pieces, trim, everywhere. Nothing was labled.
2. He had the engine rebuilt by a nationally known engine builder, it was 1/2 way through the build process and couldn't pay the bill on the work done. (So the engine was being held hostage).
3. No room, bills, money, the usual things we can run into.

It was rusty - luckily not the fenders, but it was rusty - wrecked (slid into a guard rail), and torn to pieces.

I started by cutting the cowling out of a donor car (along with the driver floor) and solving those problems:

Previous owner also hacked out a strange diamond-like shape hole here:

This project was not overwhelming at all....

Well, it is a really rare 1970 Plymouth RoadRunner, complete numbers matching.
Then I had to get busy with the engine. I paid off the engine builder and had him complete it. Keith Black pistons, slightly aggressive cam, MSD ignition, and a few other hidden goodies. I also had him dyno it and run it in for an additional fee.
After it was completed, it was ready too install, timing set, 405 hp, 410 ft. lbs of torque:

After that 5,000 bill - I moved back onto the body, welding in a new trunk and finishing the floors. What can't an angle grinder and a wire feed welder fix in the auto body world?

Breakfast in......the trunk.

Ready for the new trunk floor:

After steel was in, I used:

New trunk primered and sealed:

More floor work:

Now - to take the entire body down to steel....by hand.

I had to cut out the bottom of the rear driver:

to be continued . . .
 
. . .the trunk had a JC Whitney "wing" on it.....no wing came on this one. So I welded shut the holes and fixed the trunk.

While waiting for other supplies....
I contacted Boyd Coddington (Welcome to Boyd Coddington Wheels) and have them custom make me some wheels.
This is the ONLY non OEM part of the car.
Front: 17x7
Rear 18X12 (Hoosier D.O.T. drag radials 315.30.18)
It took Boyd Coddington 6 months to deliver these custom made wheels:

They look beautiful....but this is all the peaking you get for now.

Sweet! I grew up around those and other sweet hot rods.
We always had GTO's as our family car. A 67, 68 and later a 74. My 2 uncles always had Dart's and RoadRunners.

Sweet pics.
 
Cool. I would have gone with Torque Thrust rather than Boyds, but it's not my car. I have a '66 Coronet 2-dr HT with a 440 that never gets driven anymore. :rolleyes:
 
Mopar man for the first 10 years of my driving life ...
LOVE the color.
i ran big blocks and small blocks, those old Mopars will put up with a hell of a lot of abuse.

good for you, subscribed.

I had a deal with a wholesaler....so I got a deal I couldn't pass up. Plus, they were willing to make the size and offset I needed - so I took them up without a whole lot of research on the topic. I'm sure there are lots of great alternatives.

Fire up that Coronet man!

Thank you for all of the compliments!
 
First you build that killer FJ45 now you're doing a 'par. Come on man you're making me feel bad for not getting to the '74 Corvette and '70 Chevelle in my garage yet.

Edit: Paint looks good! :grinpimp:
 
Doors are finished being painted - alpine white inside.

Yes - the PO hacked for speakers, lame. Will be hidden with door panels however.

Now we are working on the front end, piecing it together first, and then will remove it to put the engine on, etc..

I have to get a new pitman arm. The stupid things are 150 bucks. I wish they would have designed them with a removable ball joint, but its all one pieces which means you have to replace the entire arm. Stupid.
 
Long delay - but much has been going on - sorry.

I put 4.10's in the rear. 410 hp to those tires should be fun. Well, more spicey than a 2F anyhow.

Radiator, Interior, and glass is all that's left. Well, bumpers too I guess.

It's a good thing I am rebuilding a BJ42 at the same time.
 
get back to work on that BJ42!

Hey, great work though...
