I am pretty sure it's a Louisiana car. Been in a garage since the early 70s. The numbers matching 440 6 Pack is intact, but not in the car as shown. I believe a 67 440 was built to race and installed very quickly once the A12 Bee was bought and brought straight to the dragstrip. Original paint...

Initially I got the Promax braided 6bbl fuel line kit because it looks fantastic and may have performance advantages, but I am so happy with how much EASIER it makes all aspects of servicing the carbs! ANYONE who runs the Holley 6bbl carb system should know how much EASIER it is, by leaps and...

I need to know what to ask for my factory original V-code K-member. It has the skid plate and "coin" date code. I have had my front suspension completely redone with QA1 K-member and front suspension components, except for the SPC UCAs. Borgeson power steering box and a number of other changes...

EDIT: Hotter may, in fact be better if for no other reason than power production. See linked article. https://www.allpar.com/fix/engines/cooling-system-about.html I have read the long "tuning a six pack" post that is adamant about everything that is stated in it, and that includes running a...

I just installed a dual wideband O2 sensor system. Innovate Motorsports. It reads the A/F ratio in real time and displays each side of the exhaust on the gauge. My question is Does the Edelbrock/Chrysler aluminum 6bbl intake feed across the engine, a 50/50 mix, or do the venturis of the...

Posted in the "Fuel and Air Systems" forum, but looking for as many opinions and information as possible. https://www.forbbodiesonly.com/moparforum/threads/fitech-3x2-bbl-system.153635/

I got the majority of Promax 6 bbl upgrades available, and likely the couple I missed will be added when I send them my 3 x 2bbls. My 70 V-code (71 motor) 6 bbl overall runs good. Nice kick in the *** when the outboard carbs open gradually under vacuum, which I can feel the smooth but powerful...

I'm going to order it. They swear the plates fit our Mopar Holley 2 bbls. That will be the first thing I check. I'm sending my 3 2bbl carbs to Promax soon for the whole kit of parts they offer to be installed and "pre-tuned" on their dyno mule. Outboard carbs get the jetable metering plates...

Happy New Year to my 6 bbl cousins! After my 6 bbl 440 has not been run for a week or more, it takes a lot of time cranking it over to get fuel into the carbs-at least that is how it behaves. This has always been the case since I bought it 3 years ago. Once it gets fuel, everything is fine. I...

I have had less problems than some with my 6 bbl setup on my 70 V code Roadrunner. I have tuned and tweaked, with help and advice from Bob "Mr 6 pack" K, Phil Phish, and people on this forum. Even though I don't have an A12, I LOVE 'EM and they are the closest thing engine/driveline-wise to what...

I have a 6 bbl "spacer/fogger" based Nitrous system available to me that I am considering buying. Anyone use one on their 6 bbl setup? Details of the experiences? Thanks.

Ok. Because of the way FBO designed my distributor, for my motor, I have to connect a constant manifold vacuum source to the FBO distributor's vacuum advance can. I found one under the center carb, where the choke vacuum diaphragm is connected. I assume that there are no other constant manifold...

I just bought a Walker carb rebuild kit: 15395A for the center carb and it comes with a lot of parts, including replacement main jets. Any idea what size these are? Their size is not indicated anywhere with the kit. Barring a definitive answer, should I eyeball them for size comparison to the...

Who is using them? Motor mods you have (if any)? Jet size that works best for you? I have a set of TTi 2"primaries headers on the way with a 2 1/2" exhaust system , and I am thinking that may be conducive to some outboard carb rejetting. Also is anyone using their metering block? Other options...

Since I have a 6 pak 440, would this be a good forum to ask carburetor questions? I'm not sure, but I don't think my outboard carburetors are opening.
