1971 Plymouth Valiant "Granny Smith"

[Joyboy13257]

Per the recommendation of one of the members on here, I have decided to move Granny Smith's build thread to here (like it should have been from the beginning). First posts will be direct copy and pastes of my posts from the other thread, and then after that I will be updating to the latest!

Excited to be part of this forum finally! I’m no stranger to Mopars, with my first one being a 1989 W250, but I have mostly dealt with 1980s Dodge trucks (I just finished a 2 year rebuild on a 1989 Shelby Dakota) and the last time I worked on a Mopar this vintage was 2021 when I took my 1971 Polara to begin its restoration (4 plus years later it’s still in pieces). The story of this car and what it means goes back a little…

Back in April 2024 I went down to a buddy’s place to pick up a bracket for my Shelby, and saw this Valiant (his dad’s) sitting there in the yard. I knew it would be a perfect car for my then 14 year old brother, but I was in the middle of the Shelby rebuild and didn’t have time, money, or space for it. That summer my brother finished middle school and I decided to bring him to Chrysler Nationals at Carlisle for the first time, the same thing our dad did with me when I was about to start high school. That trip transformed my little brother into a car guy, so I knew I could prime his mind with A-body thoughts (especially since I’d be the one buying and building it). He survived his freshman year with flying colors, having major roles in both school plays and being one of the best percussion players in his band and marching band. When I was his age, I did well in school but barely survived the social aspect, but I knew I had an awesome Mopar to come home to. That’s when I devised the plan- I was going to surprise my brother with his first car.

I went down in early August to look at the car again (and get some pictures of it), and I made a deal with my buddy’s dad on it. Had to wait for a government per diem check to hit my account, and last night my dad and I went with my buddy Cade to pick the car up.

As you can tell from the pictures, my little brother is over the moon, and my collection has grown to 6 Mopars.

Thank you all! Now for the car:

1971 Plymouth Valiant. 51k mile almost all original 318 V8 car with factory power steering and A/C, but manual drums. Was stored in a barn in Lynchburg VA and had some small stuff (side trim, one fender emblem) removed, and someone had busted out the driver front window, leading to chickens turning it into a temporary chicken coop. Someone had also backed into it at one point and crumpled the fender/bumper. Interior needs a lot of help, but the only rust I’ve found on this car has been in the front floor pans, and they’re not large enough to be really concerning to me. You can tell from the pictures, but the rest of the car is stupid solid!

No idea why the pictures didn't post the first time (stupid technology), but hopefully this better.

This was how I first saw the car in Spring 2024. My buddy kept the SBP Rallyes but they look really good on it.

Had a close friend help me bring it home (he knows how to drive with a trailer).

As you can tell, my little brother was in shock and awe over his first car.

Now some pictures in the daylight.

Obviously the money shot side.

The not pretty side...

It's a shame because this fender is otherwise solid. I did talk to a friend of mine who specializes in rusty metal and he thinks he may be able to get this banged out.

Crispy underside, very original, and very rot free.

More rustlessness

The ugly side. The chickens were not nice to this car.

51,846 miles on the odometer, and judging by the originality, it is accurate.

Some more initial pictures. Interior is in need of alot of love, but that is what happens when it becomes a chicken coop (or sedan?).

Small holes in both floors, plan of attack will be neutralize rust and fiberglass it.

Basic and original 318 2bbl. Was excited to see that it has the better cooling package because of the A/C (thicker rad, 6 blade fan with clutch).

Yes you can get jealous over these floor pans. And hopefully we can get the original radio reinstalled (though it will be slightly modified with a bluetooth receiver).

And fender tag photo. Pretty low option.

Had to get the ugly wheel covers off. Plus my brother wants body color steelies with dog dishes. Other side still has the full covers for now.

As you saw above, the original seats were awful and I wasn't about to spend over $1600 on just material (SMS Fabrics was the only company that has L3F7). Instead, I drove 3 hours to Salisbury to pickup a front bench seat and dash pad from a 73-74 Dart for $150 (along with a set of 10x2.5 backing plates for free from another buddy).

Meanwhile the following weekend I sent Dad to the Fall swap meet at Carlisle to pick up an almost matching rear seat for $50, and then he found some more goodies (using those 67-68 hubcaps instead).

And then my eBay find- a full (or close to full) set of correct green seat belts from a 1971 Dart sedan. Unfortunately almost every female buckle is missing the plastic.

Decided the best motivation was to get at it and start cleaning, and I wanted to see what other treasures were hiding (I knew of one in plain sight), so we got to work.

Honestly alot cleaner than I anticipated. It will get the same treatment my 1971 Polara got on the floors, but it was alot more solid that I thought it would be.

Old seats out, new seats going in. Peep my Polara and D150 in the background. In the post above you would have seen my W250 and Shelby Dakota...I am a Mopar addict.

Treasure number 1- full broadcast sheet in the rear seat back. I could see it through the rear window, and it is severely sunfaded but complete.

Treasure number 2- remnants of another broadcast sheet in the front seat bottom.

Treasure number 3- a true factory build sheet! I have not seen another.

All the goodies together. Also found a AAA membership renewal from a past owner (who unfortunately passed but in a weird way, passed a week after my little brother was born) that confirmed where the car was from (Roanoke/Lynchburg Va area). I have reached out to some next of kin and hope to hear back from them.

New seats in! Front seats have to come back out because one of the tracks is rotted, so I have to swap over the ones off the original seats (it also has a seat spring that is creaky). Learned that Mopar changed how the rear seat backs attached, but its nothing some self tappers can't fix. And yes, before you say it, they are the wrong shade of green, but they will be covered with a cheap Mexican blanket seat cover for the forseeable future. Remember- 16 year old's first car.

Onto the next step- rebuilding the Carter BBD 2bbl carb. Somehow this is my third BBD rebuild (helped my uncle rebuild the BBD on my 1971 Polara's 383 and I also rebuilt one off a Super Six that I was going to throw onto my 1984 D150).

Carb off. That was easy.

Carb on the bench and ready for disassembly. Was a pretty dirty carb on the outside but surprisingly clean on the inside. Whole reason for the rebuild was for a reseal and accelerator pump.

Carb apart and ready for a soak in Berryman Chem-dip. Not too dirty on the inside.

After the soak, I found that the choke plate screw had broken off at some point in the past (I broke the other one off trying to remove it). A drill bit and a tap fixed it and some new brass screws got it good.

Ready to go back together. So shiny!

All ready to go!

Back on! Now I have not had time to sit down and tune it, so at some point I will get around to that. Super eagle eye people will see a few issues with linkages and spring locations. Also spent a solid week trying to find correct clips and screws to fix some of the missing hardware I was unaware of until I put it back together.

A face only a mother could love. But a face I like to see every time I walk in the tent.

Could not live with the hideous wheel covers, swapped on the other two blank dog dishes. So much better, will look even better with colored matched 15 inch steelies and those earlier dog dishes from a few posts prior.

We have lights! When I bought the car it only had headlights and taillights. Swapped out both relays and some new bulbs got the park lights/turn signals working!

Kept that train rolling and went all the way around. All but one side marker bulb needed replacing, but some new bulbs later and even the wrinkled side was working!

Interior light too! Helps a WHOLE lot seeing the inside now.

Onto the rear and got the reverse lights and plate bulb working!

Even had the little brother help me too towards the end, especially since it is his car and I have been doing most of the work and buying everything.

Was going to park the car in the front yard with the magnetic reflective christmas lights, but she did not want to start or run long (did not have a tachometer yet to hook up).

And finally some goodies! Been doing some research and parts collecting for the "best" combo, and rather than going the cheap route and buying a Chinese intake, here is what I got:
- Edelbrock LD4B for $325 from an awesome guy named Robert Calimer just over the MD/PA line
- 635 CFM Carter AVS 6125S (from a 1971 N-code 383 HP car) I bought at Carlisle probably 2019-2020. I rebuilt it back in 2020 or 2021 but had no idea what I was doing, and having sat in my shed for 4-5 years, some dirt dobbers made their presence known, so another rebuild may be in the future.
- M/T valve covers for $125 from a gentleman in Baltimore. Will make it look cool.

Now these parts aren't going on immediately- these are more so a treat for the car once it gets on the road. And of course I'll need to do a cam swap too (can't decide on the XE256H or XE262H, especially since we will be rocking with stock torque converter and super tall gears in the 7.25 for the immediate future).

 

[Joyboy13257]

Now to catch everyone up to speed. Winter was cold and snowy, and the rebuilt BBD was nothing but problems. Come to find out, the BBD was about 10 years older than the car!

The poor man's six pack. The BBD that was on the car is in the far back. Knowing it was bad, I bought the one in front of it off eBay, knowing it would need to be rebuilt. However, once I opened it up, I found out it was missing a bunch of parts and would barely even be considered a parts carb. So back I went to searching, and fortunately a buddy of mine in Georgia had a 1973 Satellite parts car with a BBD, so I took a second gamble on that.

A bit dirty, but seemingly complete and free moving.

Deja vu x3. This is before the cleaning...

...and after! I am still shocked by how well Berryman's Carb-Dip works. I only soaked the parts for about an hour or so, then ran some brushes and carb cleaner through the orifices.

End result- looks brand new! But how will she run?

Back on the engine! I did have a new pre-bent fuel line from the pump up but unfortunately the bends were not correct and didn't work.

It runs! A snort of starting fluid down the throat and it fired right up! Some very light fiddling with the mixture screws (2.5 turns out from seated) and the idle, and it comes to light on the first crank!

 

[Joyboy13257]

Now that it runs, it was time to do an oil change. While it was idling to get the old oil moving, I revved it up a little and something fuzzy jumped out the exhaust. Ended up being a mother mouse and a couple of newborn mice attached to her!

The dino juice going into the engine. Might bump it up to VR1 10W40 or similar once we get it on the road.

Another shot of the underside. I don't think I should be able to see the back seat from here.

Also now that it is running, it was time to begin spending my money to make the car better!
- Aluminum Master Cylinder w/ adapter and 7.25 BBP axle shafts from Dr. Diff (also have their proportioning valve/distribution block too)

- CPP 11 inch disc brake kit! Comes with everything to convert the SBP drums to BBP discs, including new spindles and upper control arms (one of the only kits that offer this). Did have to wait over 6 weeks for them to ship, but ordering through Summit helps eliminate the shipping costs.

Other parts not seen:
- Inline Tube Brake, Fuel, and Transmission Cooler lines
- KYB shocks
- Kanter steering linkage kit (steering and idler arm, tie rod ends and sleeves)
- NOS Moog Camber Bolts
- Rear brake parts for the 10x2.5 inch rear drums
- New fuel tank and components
- New aluminum radiator, water pump, thermostat, hoses, fan clutch
- New 1 qt deep transmission pan and bolts
- New firewall gasket kit

Granny Smith looks nervous, but it is because it's time for the disc brake swap!

We have lift off! I won't lie, jacking it up high enough for the jack stands makes it sketchy to be around.

The old

After about an hour, the driver side drum came off with very little issue! The biggest hang up was the upper control arm bolt not wanting to come out.

Passenger side drum off! Took maybe a half hour.

Seeing how much progress I was making, I kept it going and got the old steering linkage out.

Only the center link was retained, everything else is from Kanter (though they no longer honor the FABO discount that PST used to have).

Back in! The hardest part was tightening down that nut on the steering box to 170 lb-ft of torque.

 

[Joyboy13257]

What comes off must go back on. First up- NOS Moog Camber Bolts. Now I know must also go with the offset bushings as well, but with the control arms having new bushings already, I decided against it (though it may bite me in the future). I don't doubt these are easily a decade older than me!

New upper control arm in! Yes, I kept the lower control arm and strut rod untouched, mainly because I didn't have the money to upgrade to QA1 tubular ones or the skills/time/patience to rebuild and modify the originals.

The backside of the new brakes. Everything is so nice, I'm not used to it!

Even comes prepacked with new bearings! Yes you do have to remove everything to bolt the new lower ball joints to the spindle.

So nice! CPP kit came set up for the pre-73 orientation with the caliper on the backside of the rotor. Because of this, I now have an extra set of 1969 Camaro disc brake hoses.

Left side

And now all finished! Note the new brake lines, brake hose, and KYB shock. One issue I did have was with the spindle dust caps not wanting to stay tight (also saw evidence of the cotter pin rubbing against the inside of the cap too). Ended up replacing them with Dorman ones that although dont sit flush to the rotor, do fit tight.

With the BBP swap, I could no longer use the 14 inch SBP steelies and 195/75R14 tires. I had a set of 15x5.5 steelies that I wrapped with some 195/65R15 Falken tires (same width but .5 inches shorter than the old tires) that I scored off Tire Rack for under $100 a piece. I was stuck between these and 205/65R15s (which were same height as the old tires but .4 inches wider), but pulled the trigger anyways. Besides, these aren't the final wheels for the car anyways.

 

[Joyboy13257]

And now we sit like this today! Still playing around with ride height and alignment, but ultimately turned out looking amazing. Current goal is to have it on the road by 4th of July, so I have a few more weeks to get the rear end converted and get the fuel and cooling system done.

And if you are not already, I post its progress on Ratty A-Body Mopars on Facebook as well. There are also a ton a videos on that page too of it.

Looks good! Can't wait to see it with the black steel wheels and small matching hubcaps all around.
was mom mouse paying rent? I can't imagine what is in the Hornet's tail pipe. it's been in one spot over ten years.

Momma Mouse seems to be moving around. She jumped out the glovebox one day when I started the car and crawled through the floor hole. Haven’t seen her since. Maybe Mr. Snake got her

Man, thanks for sharing! That is going to be a fun little ride.
