You can do it on a 67 Barracuda. Jack up the front end to get more tilt. Make sure your cherrypicker has good lift. Use the shortest chain possible.

Don't know that there is one, specifically, since you can reach the bolt with a regular box wrench, or even a socket.

The actual problem that might be caused by unleaded fuel used with non-hardened seats is valve seat recession, which takes a while to develop. I have had problems with this in high performance engines, but it doesn't sound like it is a particular problem with the six. Charrlie is right about the...

There are a couple of sizes of the 4-blade fan, since they were also used on base V8s. They are not much for cooling — the flat blade angle was designed to use less engine power for economy. When I was looking for a more aggressive fan, I determined that 16" was the largest I could fit, the...

Hmm, have not seen that on 67 or 68 pans. That's all I know.

The literal answer to your question is: "you can't". The question you meant to ask was "where do I find one of these things?" The answer is, from somebody that has a couple of junk carbs laying around. So the reasonable thing to do would be to post a Wanted ad for a carburetor air filter...

Actually, the change was between 67 and 68 — I know this because I swapped in a 68 motor to my 67 transmission, and I had to use an adapter ring. Which would also indicate that the 67 torque converter had a larger register than the 68 engine — you had it the other way around. Anyway, Vali68...

I have a Saginaw pump setup on my slant and I don't recall that piece. It was a swap-in from a later model.

Mine broke off, and I tried just that. But I could not find a nut that would thread on the stud. I eventually used one of those sheet metal quick nuts such as are used for badges and lettering. Anyway, I was looking to replace that with a right-angle connector, so I'm glad I found this thread.

I think the super six intake is designed for a Carter BBD 2bbl — that's what is on mine. A cable kickdown will work, but you need some kind of bracket to anchor the carb end of the throttle cable and kickdown cable, keeping them parallel. I just used a hardware store right-angle bracket...

Sounds like Jonn has you covered. As far as adapters go, if they funnel down to the bore hole size of the 1bbl manifold, I don't know if that would be any kind of improvement. That tiny 1bbl bore is the choke point of the whole system — you can only get so much air through it without forced...

Halifax has the right idea. One byproduct of the Prestolite dual point design is that if one point set fails completely, it still runs with reduced dwell. In fact, that's how you are supposed to check the individual dwell – by blocking one set open with an insulating block (like a wooden...

I don't know if there is a "new" option. Depending on the year, it might have had a Holley 1920, Holley 1945, or a Carter BBS. But I don't think any of those are available new. Mike's Carburetor has rebuild supplies, but my experience with rebuilding the Holleys has been poor — they seem to have...

3 plug = 60-67 forged crank, #2463430 "RGFC early" painted red. 5 plug = 68-75 forged crank, #2906830 "RGFC late" painted blue. Beyond that I don't know.

Hmm, my car has a 2-speed wiper and the electric pump. So I would assume you could just swap the switch and the pump/bottle.

The key is to know that they don't call it a "225", they call it a "3.7", that's all.

What I want to know is, how can a distributor be "Tri-Power"? Seriously, I saw some talk on Facebook... one guy thought they were great, another thought they were overpriced.

Also could take a good look at the oil visible on the dipstick. Is it discolored? What does it smell like? Pop the radiator cap and check the coolant while you're at it. If it smells like exhaust you know what's happening.

Yeah, the 2bbl is oriented like a typical V8 carb, and, in fact, is pretty much the same carb as on the 273 2bbl. So whatever works on a pre-67 V8 should be adaptable, I would think.

I don't know about the pedal... I don't have any early A's, I have done the 1bbl to 2bbl swap on a 67. I suspect it has to change, also, because you need to have a cable attachment point somewhere. You should search the forum — I know this has come up before.

Murray is right. My 67 had a Federal pump. I swapped to a Saginaw because the Federal couldn't keep up with steering input on twisty roads. Also because I bent the pulley and nobody has replacement pulleys for Federal. The swap requires a different bracket, sourced from a later year that used...

In more detail... the throttle "pull" on the 1bbl is straight down... the pull on the 2bbl is straight back towards the firewall — there is no way the rod linkage can pull in this direction. You have to change to a cable. A V8 cable is a better length than a later 6cyl cable (these are too long).

You never said what you were running for fuel. Try some premium. But it sounds like something else might be off.

Wrecking yard is your best bet. Older cars are getting scarce, but slant six Darts are still out there. Call around, search the web. Note that Valiants have a shorter wheelbase (in most years) so may not interchange.

It would help if you had a factory service manual (1971 Plymouth) or even the Haynes manual for Dodge Dart/Plymouth Valiant Slant Six. It would explain the wiring, the ignition settings, and basic troubleshooting.

Here's one more.

I found two photos showing them installed. They aren't great — I was really taking pictures of other objects. The brief answer is, they go around and behind all of these objects. It is a pain to install them even when the motor is out of the car, because they have to go around the exhaust...

It was either the Holley or a Carter BBS 1bbl. I don't know offhand for 1970. I am not a big fan of the Holley, and in general the 1bbl is a choke point for slant six performance, such as it is. I don't think a 2bbl adapter would get you much, either (you still have the tiny throat issue) — if...

My Barracuda had this problem for 20 years. Both my father and I rebuilt the carb numerous times, eliminated all vacuum leaks. Finally decided it was a tiny crack in the carb body where the idle screw seats. Swapped to a 2bbl Super Six setup and never looked back.

Oh, that makes more sense. I think it would be a straight up swap -- I can't think of any hangups, other than you will want to carefully check the flange thicknesses against your exhaust manifold. If you got the exhaust that came with it, you should be good regardless.
