I recently acquired a V-Code 70 Challenger (Ice Blue) with a dealer-installed shaker hood (installed 8-1970). Provenance to this car (the guy who sold it to me) goes back to 1974 and comes with several pictures from the days it was being races in the mid/late 70s. The car was recently restored but there are a few things that were done incorrectly and I'm fixing those things now.

When taking off the shaker assembly, I noticed that the fuel line enters the carbs from the driver's side, etc...so I called the prev owner and he said it was the original Mr. Norm's carb setup that he installed so he would not have to keep removing the shaker to squirt gas in the carbs to get it started... OK, I get it, it was the 70's...

Currently, the car starts up (immediately) with zero issues/ever... so I'm perfectly happy with the current setup and I'm afraid of changing anything, but I'm curious if there is any info out there on these setups, I've never heard of them or seen one before.

Is there any documentation, brochures, anything out there on this six pack setup ?

Thanks in advance...

It's probably the direct connection mechanical carb setup.

Well, if the center carb is 4782, it’s a 350 cfm. If the outboards are 4783, they are 500 cfm and mechanical secondaries. They were an over the counter setup available through a Mopar dealer. The bowls will all be the side hung Holley with driver fuel inlet. If they are center hung bowls with vacuum pods, they are Corvette carbs or bowls. I picture is worth a thousand words. Carb numbers will help too.

The Direct Connection mechanical carbs have always been my favorite. I have two sets sitting around here.

The Grand-Spaulding cars used Corvette carbs, with the other-side fuel inlets, and a cast air cleaner lid.
I've seen the correct #s somewhere, but don't recall where to direct the OP.
Sorry 'bout that, but I'm sure that info can be found if I was able to stumble across it.
That lid always looked backwards to me when installed, due to the lettering.

Good information, thanks.

Center carb is 4782 and both outboards are 4783 with the following list numbers:

C: 2641
F: 1380
R: 2241

Pass side:

Equally important question:

What was the advantage of this setup vs. stock ?
Why enter the fuel line from driver’s side ?

Was there an advantage or did he just want to be different ?

Thanks

Mechanical vs Vacuum secondaries
No secondary idle adjustment
Ability to change jets on the secondaries
the fuel line is due to the way holley offered them.
I have run multiple sets of these carbs on different motors since about 1976. They work REALLY well on 440's and Stroked SB's. When those secondaries open it's much like a passing gear. If you happen to be in an automatic car and it does drop to second or first it's a real experience

The reason fuel inlet is on the driver side is that is the only bowl that will fit the carb spacing using the regular metering blocks in the rear. One advantage, as mentioned, you can change the jets in the outboards. These were marketed as an over the counter carb or ones that you could get from Holley. The mechanical secondaries do give you a big kick when you get into them. I had a set on a race car and they ran great in testing around on the street. On a race cars with slicks and a sticky track, I had a bad bog. I never could spend the time to try and work that out. I went back to the oem vacuum secondaries and started playing with the springs. It went much faster and consistent without the bog. I figured if the stockers and super stockers could run as fast as they were with vacuum secondaries, I could be satisfied with oem as well.

You should fix that line to the rear carb , that little piece of rubber line is an accident waiting to happen.

it's a corvette set up and you can find a lot of info on them and I believe on the vette the fuel line has to run on that side to fit

Norm bought the Corvette carbs for his GSS builds because they were $20 cheaper than Chrysler carbs, it was as simple as that...LOL

Actually they are not Chevy carbs they are a modified Ford carb. Chevy carbs have the vacuum pods, center hung bowls and only one metering block

And vacuum pods cannot be removed? Mr. Norm told me which Chevy dealer he bought them from in 1971...

So you think he removed the vacuum pod, added side bowls. metering blocks and pumps? I read somewhere they were Ford carbs. Take a look at the old Ford tri power. They are identical. Here's a 406 Ford Tri Power.

Ford had to mount those carbs backwards to clear the distributors on the FE motors

Seriously? You can’t see the difference in the two pictures YOU posted? The Mopar carbs he has are made by Holley for Mopars. They use the same body as a Mopar six pack using std Holley metering blocks and bowls from a regular side hung Holley carb. A Mopar air cleaner will not fit the Ford setup. I’ve got about 90 six pack carbs, as well as a set of the same as the original poster. I sold a ford set long ago. Corvette outboards have a different main body Mopars. Corvettes and Ford outboards both have an air horn on them with the choke parts removed.
