I've asked many questions about putting my TR5 intake and carbs together on my 408 Dart. Got a ton of great help here. But now its time for the next step. I finally got all the fittings in place and sealed up. I have 6.5 psi of fuel pressure with switch on but engine not running and with engine...

I'm getting ready to attempt start my Dart for the first time with the 2x4 setup on it. The only thing I'm not sure about is where do I connect the vacuum secondary pods to? Any help would be appreciated. I am running Holley 600 carbs on an old TR5 Edelbrock tunnel ram. Thanks Rod

Working on a 408 in a 66 dart. Im getting ready to install my TR5 edelbrock tunnel ram and I need to ask a few questions. Ive run into a few issues with this intake manifold and running some fuel lines. I was wondering what others have used as a fuel block to make a nice hookup? I bought a fuel...

Im getting ready to try my 2x4 set up on my 66 Dart with a 408 engine. I will be using a pair of edelbrock heads, 1.5 rockers, 590 lift on both valves, compression should be right around 11.5-1. I am using a edelbrock tunnel ram with 2, 600 vacuum holleys. Factory jets in the primarys are 65s. I...

Im rebuilding my 2 1850 600 CFM carbs. Everything seems to be going back together with no issues but I found one thing Im not sure about. Now I bought these 2 carbs used so Ive never run them but during the rebuild I noticed that there is an open vacuum port that goes from the side of the carb...

above is a pic from my Holley 600 with vacuum secondaries. I bought a pair of theses carbs from a member here over a year ago and I’m finally getting around to rebuilding them for my tunnel ram on my 408. The throttle lever on the inside is rubbing the bowl transfer tube when the linkage is...

A little over a year ago I purchased 2 Holley 600 carbs from a member here. Carb numbers are 1850-11. Under the carb numbers are 1129. what does that number mean? Is it a manufacturing date? Now these are vacuum secondarys and my plan is to use them on my edelbrock TL5 2x4 manifold. Someone in...

Quick Fuel 43-4QFT - Quick Fuel Super Progressive Secondary Linkage Kits I was wondering if anyone has tried this linkage kit on a Holley 600 cam with vacuum secondaries and did it work out? I’m going to be getting my 2x4 set up ready to install and I’ve got a bunch of questions so I’ll be...

I have a 66 Dart. Factory tank but it has been modified for a sump kit welded in. The fuel lines have been increased in size to 1/2” going from the pump just below the tank up to the fuel regulator mounted on the passenger inner fender near the alternator. From there the fuel one runs to carb...

Was wondering if anyone else has ever ran into this issue. Im working on my 66 Dart with a 408. With the build I did I replaced the factory fuel lines with 1/2" aluminum lines and added a return line back to tank. My system goes from tank and runs up the inside of the frame connectors. Then it...

Are there any good defining articles to tuning a holley 4 corner carb? I need to work with mine once I get my cooling issue cured. I've never had a 4 corner carb before. I am working with a 750 dp on a 408. Thanks Rod

Im wanting to understand some carb theory and tuning knowledge ( holleys) and even though I have worked with many carbs (holleys) over my life I have never been "schooled" on the how it works internally. The reason I want to understand this a little better is because I plan on going to a 2x4...

Im looking at an offenhauser 2x4 intake that is a single plane with Carter AFB 500 CFM carbs. The carb numbers are H7 9500 A. The front carb has a choke and the rear one does not. My question would be how well do they work on a performance car, how tunable are they for performance and how...

I built a 408 with a pretty healthy cam .575 int and exh lift and Im going to be running an edelbrock 2x4 setup. The engine builder estimates it to be around 500-525 hp. I bought the setup a few years ago and it had Holley 600 carbs that came with it. I rebuilt both of them but havent used it...

Trying to move forward and get some work done tonight I sealed up everything on the fuel tank and hooked up my smoke machine. Felt good to see that with 15 PSI there are no leaks. Now I can install it back into the car and start to run the new fuel line to the front. Rod

I am trying to find a place where I can get 3 of the clutch head screws that go in the metering plate for the secondarys for a holley 600. Also I need to find 3 base plate screws. Any outlet or does anyone have some spares? Happy to buy and cover shipping. Thanks Rod

Im working on my 66 Dart. It will end up with a stroked 408 and will be running a Holley 750 DP that has been custom built by SMI. I plan on Drag racing a few times a year so I dont want anything that wont pass a tech inspection. I have added a sump to the tank and thats where my question...

Last summer I bought an Edelbrock TR5 tunnel ram that came with 2 holley 600 carbs. It also had 2 holley kits included but the carbs had been sitting for 10+ years. I rebuilt the first one this fall and tonight I decided to go ahead and start on the second one. Took everything apart and into the...

I finally got my tank back and the sump and return bung has been welded in. I plan on putting the vent in the fill neck so I think my tank is ready, but I thought I would check to see if any other mods need to be made. I will be painting the tank with the black POR15 epoxy paint will wait for...

I installed a sump and need to add a return line. I am feeding with 3/8" aluminum from an electric fuel pump. The system will have a return from the regulator. First question is what type of fitting did you use to go into tank. Any pics of what you did? Second question is should the return be...

I guess this could be posted in exhaust or fuel. I have a 66 Dart that I am making changes to and I ran into a roadblock and would like to see what others have done and pics of your solutions if possible. Im sure I am not the first person to run into this. So here it is; I have moved my...

I am building a 360 stroked to a 408 for a 66 Dart. 904 trans 3:91 gears. 10:1 pistons with .575 solid roller. I found an old edelbrock tunnel ram 2x4 setup that included 600 volleys. Came with kits to rebuild them so I took the first one apart and the carbs are in rough shape. Lots of old...

I'm working with my 66 Dart. After looking at the gas tank position I've come to the conclusion that I'm going to have to go to a fuel cell in order for my electric fuel pump to be below the tank so fuel can flow to it. I was wondering what others have done so you can still fill the cell from...

I have questions about the safest method of welding a sump into my existing fuel tank. I really dont want to lose my spare tire well so I dont want to go with a fuel cell. However I dont want to risk a tank exploding and injuring anyone so a fuel cell may be the answer. What methods have...
