Thinking that you are looking for a 2 bbl carb with the same base as a Carter BBD, a Holley 2280 has the same base and was used on 318 engines. Throttle and kick down connectors may not be identical but will be similar.

That could make it run better or make it run worse, it all depends upon how it was done, if vacuum hoses were plugged, if the carb and timing were adjusted. Regardless that engine should start and run smoothly and give decent performance. What I would do is make an evaluation of the engine as it...

I am going to drain the fuel tank tomorrow. The reason is I am adding in Meter Match unit. Back in 2016 when I put FI on the car I put a Tanks INC fuel level sensor in. It stays on full for a while then moves to near empty when there is still around 1/2 tank of gas. As the car was drag race only...

It is a 450 L per hour Walbro. The end will be open so yes I expect it to come out fast.

Wanting to empty the fuel tank, it is about 1/2 full and I have storage for the gas until I use it. What if I break one of the existing lines open, use a fitting to attach a length of braided flex hose that I have around and use the in tank fuel pump to empty the tank. I have a manual over ride...

thanks for the responses, very helpful

A few years ago I replaced the OE fuel tank in the 68 Barracuda with a new tank from Tanks Inc. Over the next few days I am going to be working around the fuel tank to improve the accuracy of the fuel level sender and I was wondering, per the title of this post. Does the topside of the tank fit...

The photo from clementine is exactly how mine looks also. Except that I rounded the corners to not have stress concentrators. An easy way to do that is to drill a 3/8 inch hole at each corner prior to doing any cutting. Then use the metal saw of your choice to connect the holes back toward the...

I also have a Tanks Inc fuel tank with in tank pump in my 68 Barracuda and wanted to put in access to the fuel pump. I too noticed that the sheet metal in that section was double thickness. But I figured with the cross member support that the shocks mount to in the same area it would still be...

If you are looking for replacement fuel tanks and / or in tank fuel pumps check with Tanks Inc. They have good stuff, Walbro pumps ….

I made the fuel lines for the 68 Barracuda from annealed stainless from Summitt. I have MPFI so it has a 3/8 delivery and return lines. I also drilled an extra hole at the torsion bar mount so both lines run through that mount. I made a separate section about a foot long where they pass through...

Why the return? If you are changing over to FI you will have better pressure control by using the same size line for delivery and return.

I run a MegaSquirt MS3 Pro MPFI. The ECU was new in 2016, so MS has newer stuff available. I can say this in 5 years of use the ECU has been bulletproof. I run a ported GM Throttle Body using a shop built adapter and all GM sensors, cheap, available anywhere and also reliable. The Tuner Studio...

So, if a person does not have a distributor machine handy, he could still drill view ports into a distributor cap and use a timing light to observe the position of the distributor cap conductor and the rotor while the engine is running at minimum and maximum advance? Interesting.

I bought a fuel tank from Tanks.inc for my 68 Barracuda. Very nice looking part, powder coated on the outside. They have several options for an in tank electric fuel pump. I will add that their replacement fuel level gauge has the same common fuel level sensing error reported by others. Although...

I tied the ign 1 and 2 together and never had an issue, that is a common thing when upgrading the ignition to a HEI or MDS box. I have never heard of anyone adding a diode. The simple way to get full voltage to the ecu is to use the Ign 1 and Ign 2 wires tied together as the trigger for a...

Actually no, the same engine skills it takes to tune a carb are used with FI, difference is the laptop is the tool, the same way a screwdriver is a tool. And Rusty, you are a good guy, but you can’t have it both ways. In post #175 you say you don’t have the skills to tune a throttle body FI...

Interesting comment that FI is only about emissions and fuel economy. Totally ignores the fact that since MPFI has been broadly used in new car production there has been a marked uptick in motor performance, across the board. Everything from 295 hp v6 grocery getters to over 700 hp Hellcat...

I did not realize it until you mentioned Contour fans, did not know it was you that did that write up. That is an excellent article. I used that information when I put a Contour fan in my 68 Barracuda. My advise is, when you get a response from someone that admits they need to “stop the car to...

GoldDuster318,, when YR makes comments like that, just let it go, obviously he is troubled, perhaps off his meds,,, I was giving him some credit earlier when I said he probably knows more about cams than I do, then he makes the comment ,,,,"Roller cams are another needless, useless expense...

Keyboard tuning with out a laptop

Never said that you or anyone else is stupid, I did say, just because you don’t understand something it does not make it Bullcrap. Look, you probably have much more knowledge than I do on cams, that does not make me stupid or you brilliant. Technology changes, it’s ok to change with it, or not...

If you’re carbs are even close, you can get almost everything EFI will do without the rest of the bullcrap. lets do a test,, you have a carb set up, I have MPFI FI after looking at plugs or AF meters or what ever tool we choose, we both decide that the motor is a bit lean on the top end and way...

Concerning the comment in Post #8, either FI or a traditional carb can give excellent performance with the proper tune. The biggest advantage to FI is how quickly fuel and ignition maps can be adjusted to accommodate changes in atmospheric conditions including elevation. FI will do that as you...

I have had a MegaSquirt MS3 Pro on the 68 Barracuda for nearly 5 years. I did all of the installation and the tuning. It has been 100% solid. Concerning the comment about voltages, nothing difficult to accommodate to anyone familiar with wiring in relays. And yes the main grounds for the ecu...

Keep the gauge under the hood, use an I phone or a go pro to monitor during testing. This ain’t brain surgery.

Yes, they were very helpful with me. FWIIW, I have an AEM AF gauge in another vehicle and it is a daily driver type of vehicle, have over 40,000 miles on it with no sensor or meter issues. Go figure why the one with very light use failed first.

When the Bosch O2 sensor failed on my AEM unit,, it would go to full lean immediately after its warm up cycle. My failed sensor did not have a lot of use on it. Was maybe 3 years old, but in a drag race only car with probably 60 runs on it. I called the AEM Tech line and they had me do the ‘Gas...

One of the last big projects that I had a hand in while still working was the Navistar- PSI 8.8L propane engine project. PSI has a really slick propane fuel injector that atomizes liquid propane directly into the cylinder. Same principal as a gas or diesel common rail FI system. The propane...
