Hello all! I'm trying to get my '63 Valiant convertible back on the road. A little history, my Dad bought it for me as my first car. But, after realizing how much work it would need, he decided to get me a '74 Newport and put this one in the barn till we could gather parts to fix it as a father-son project. That day never came for us as he passed away a few years ago. But now, I've got most of what I need (at least I think I do), so I've decided to tackle it as a tribute to him. However, as I've been taking the car apart, I've been noticing things that don't make sense or match up to what I've been reading about V8 swapping early A-Bodies. The previous owner did swap in a 318, but there were a few things my Dad said he didn't do correctly. I was young at the time he found all of this, so I didn't really understand all of what he was saying. And now my memory is shotty. So, I decided I'd let all of you weigh in on this car and my plan to move forward. I'd also like to know why any of this was done, as it helps me better understand things. Here's some of what I've noticed.

1. The center link was not upgraded to a V8 one and rubs the oil pan.

2. The arm from the steering box to the steering linkage on the driver's side (the pitman arm? Please correct me if I'm wrong) looks weird. Almost like it was cut and welded to fit. It's also rubbing on the starter.

3. The K-Member was definitely welded on. I can tell by the messy welds on the top and underside. That's the one that confuses me. No where in my reading for doing an early A V8 swap have I read that you have to weld anything. Why would someone do this?

3. The trans cross member was modified to fit a 727. This kinda made sense, till I read somewhere on this forum that you don't need to do that to fit a 727 in. I'm more confused on that and would like a clear answer.

Here's what I was told. The engine and transmission including the shifter were taken out of a '77 Volare and swapped in. The guy basically built it in his garage. It was running and driving at one point, and I used to drive it around the neighborhood. But over 45 mph the thing would start swerving all over the road and it was hard to keep straight. It also had an overheating issue that we could never figure out.

So my plan is as follows and I'd like to get some feedback on it before I dive too deep. I am taking the engine and transmission out, as the engine had parts robbed off of it and sat open for a number of years and now has rust issues. I have a '65 Barracuda parts car, this is where I'm getting my parts from.

1. Swap in the Barracuda K-Member. I was told it should fit and have measured the bolt-to-bolt centerline on the k-members of both cars and everything seems to line up. I'd like confirmation on this though before I dig in.

2. Swap in the Barracuda V8 centerlink. I might just swap in all the steering components for that matter. But again, I'd like to know if they'd fit, especially the pitman arm (hope I'm getting that term right).

3. Replace the trans cross member if needed. Either with the one from the Barracuda or with another one if there's a way. I'm also open to having one modified.

4. Swapping in the 273 from the Barracuda. It does seem illogical to go from a 318 to a 273, but it's mainly because I wanna run my D-64 dual carb manifold(it looks so cool) and that 273 is a '65 with the correct bolt hole angle.

5. Swapping in the torsion bars from the Barracuda. I was told those are for sure the slant 6 torsion bars still on it. And if I'm swapping K-members I might as well swap the torsion bars too. But will the ones from the Barracuda fit?

How does this all sound? More important, is there a way to do this better? Or am I just waisting my time? Thanks everyone!
 
Welcome aboard! You’ve come to the right place for answers. I would remove the 65 Barracuda front suspension including the K, engine, brakes, centerlink etc as a unit. I suspect the Barracuda’s (we’ll call it the Donor) transmission is a cable operated similar to what your 63 would have had. Leave it attached to the engine and balance ad needed when you remove everything up front.then you’ll have all the right parts ready to rebuild or refurbish

You may not be aware but 63-66 K’s are all the same whether V8 orslant 6. The V8 torsion bars from the Barracuda would be an upgrade over your slant bars. They are L And R specific

I am in the process of converting my OEM slant 65 Dart wagon to a 273/235 V8. I am using aftermarket torsion bars and converting the brakes to 73-76 discs

Give me a shout if you’d like mire detailed infir on your swap

I will definitely hit you up, thank you!

On the k-member, thats what I thought! Which is why I'm so confused as to why something was welded on there. The Donor k-member does not look like that at all. Could it have been something wrong with the original that he welded back together?

On the brakes, the Valiant was already upgraded to discs up front. I'm not sure of the year though i would assume it's from the '77 Volare he was supposed to have pulled all of this from. Is there a way to check via part numbers or some other tell tale signs? I will need to do the brakes on it and don't know yet what to buy.

On the transmission, the cable operated 904 is long gone from the Valiant. The 727 thats in there was shifted by some homemade linkages that were welded together. The Donor car has a floor mounted shifter in it actually. Is that still cable operated? I might like to use that as it fits the car better. Can I put that shifter and linkage on a 727?

Thanks again!

It’s auite posible it was damaged or something else wrong with it. Your best bet is use that 65 K

If they are from the Volare, i think they are the single piston brakes similar to the 73-76 A Body discs. Check the ritor size and report back. If the PO used the stuff from the F Body, likely he used the somewhat taller spindles and possible larger caliper adapters. A lot of people use the FMJ stuff so you you shiuld. E OK if so.

IDK abiut part numbers on FMJ brakes. Other might chine in for positive ID.

Use the 904, the shifter and cables. Your 727 ought to go to someine who can actually use it. The Mickey Moused shift linkage needs to go in the trash. Use the 65 904, the dual cable shifter and cables. The 904 is already mated to the 273 (big plus), you have the correct cable shifter (big plus) and the correct cables fo mate to the shifter and transmission (big plus) and all the correct mounting brackets on the tunnel (another big plus!). It’s a no brainer IMO!

I like your idea of the D64 on the 273. I have the D66 for 66-later heads which I’ll be using with a V8 mated to a 64 904 dual cable transmission in a 47 Dodge
 
That motor in there has spool type mounts. That's why he welded the ears on the k frame. Not familiar what interchanges on a 63 but if a 73-75 a-body K frame fits I would go that route. Better motor mounts. You would need to use that year sway bar and I believe steering parts as well. Get a whole assembly with disc brakes and all. It will give a larger 4.5 bolt pattern though. Or get a 68-72 K frame set up.
Guy's, please correct me if I'm wrong.
Welcome aboard and good luck.
Sorry about your dads passing.
 
The k frame and the cross member have not been modified. They've been butchered. No offense. You need to replace them with the correct pieces.
 
I agree with post# 7 above. Seems like whoever put that poor thing together, ruined everything they touched. Looks like they tried to use the new steering linkage from the Volare. Also verified that it drove horribly. I'll add, use as much from the Barracuda as you can, especially the K frame and all the steering. Check the numbers on the torsion bars or measure them and use the thickest ones. Are you sure you have a 727? On an early A I prefer a 904, they just fit better.

The pan is tell tale. Volare, no that would have been a 904/999. 727's only came behind some 360's and all 340's in cars. Pickups and vans could have 318's and 727's. That brings up another question then. Are there weights on the torque convertor?

Depends. If it was a Volare Road Runner with a 360, it wouldda got the 727.
 
I agree with the recommendation that you use all the '65 Barracuda parts and get rid of the F-body stuff.....except for maybe the brakes if it's been converted properly and matches the rear end bolt pattern. Being your convertible is a '63 model, just what sort of butchery did they do to the firewall to make a V8 fit? If the drivetrain was moved forward to get clearance, you will be faced with a firewall modification to get enough clearance for the distributor area of the engine when using the '65 Barracuda parts.

Unfortunately that would be unbalanced with a 318. I was thinking the 318 and trans and other parts came from the same Volare. We are all just guessing here. Looking at was done to that poor car, nothing would surprise me.

Ah, I did not know that about the Volares. I wonder if he maybe got the trans somewhere else or if the Volare story was just a myth/mispoken to me. I don't know if there's weights on the torque converter actually. Is there a way to see that with it mated to the engine still?

Yes, you should be able to see rectangular weights when the cover is off. If internally balanced, for a 318, all you will see is the 4 mounting pads. At this point the seller should have zero credibility.
 
Doesn't really matter if you're going to use the 273. It's crank won't mate with the 727 converter anyway unless you want to make a custom one with the correct small button on it. Or, use the crank out of the 318....

The firewall was modified to get rid of that hump so the distributor would fit. It was not done well, as it's definitely not metal thats covering the hole. Not sure what I could do other than weld a piece of metal in there.

Indeed. These cars are all so old now, it couldda had an Allison Aircraft engine swapped in.

There was no cover on it, guess he forgot that. I didn't see any weights, but here's a picture to confirm. Do I need to turn it any to find the weights?

Still won't fit a forged 273 crank regardless of weights or not.
Yeah, at this point I'm going to do what @65 Dartman suggested and pull everything from the Barracuda as a unit (except the brakes) and use that. Seems like it'll be a lot easier to go that way. The reason I'm not using the Barracuda brakes is it has a disc brake kit from I don't know where that has a different bolt pattern than what's currently on it (4.5" I believe). Speaking of which, does anyone know where these wheels are from? I like em on the car, just never knew what they were off of. They kind of remind me of C-body rallye wheels.
