Mr. Gasket 1933 Carb Adapter

Installed this adapter on a 73 ford F100 FE360 manifold. Took off the original two barrel and installed this adapter and an Edelbrock 1406 4 barrel carb. Everything worked out flawlessly. all I had to get was a power brake fitting from edelbrock off of Amazon. The results were dramatic. Smooth idle and tons of power.

Great product, very much so needed.

I bought to adapt a small bolt pattern 2 bbl to a large, Holley or Motorcraft, 2 bbl. And it didn’t work for that. It was a well made unit with a die casting that fit the nuts into the hex holes. It can work for either 2bbl to 4 bbl but the 2 to 2 leaves a big gap for vacuum to escape.

used this to put a carter 4 barrel on an old AMC 343 2 barrel. i see other reviewers had issues with fitment and clearance but there are a number of different configurations. you will likely need remove your studs and replace with the included hardware. some manifolds, such as mine, had an intermediate plate that needed to be removed. but otherwise all gaskets, hardware were included and fit perfectly. bolt adapter to manifold then carb to adapter. i cannot speak for the reverse (4 barrel to 2 barrel) but i believe it is machined to then use the same allen bolts in place of studs (you would have to bolt carb to adapter and then bolt adapter to the manifold in that sequence).

I needed this for an old 1970 f250 fit perfect and it came with gaskets and bolts perfect seems to be quality

This fit on my 2-barrel 302 carburetor and it made it fit on a 4-barrel intake manifold. Was really easy to hook up and made it more fuel-economical!

I needed to place a 4 bbl carb on a 2 bbl manifold so I could test it after installing a rebuild kit and make idle mixture adjustments before putting the carb onto the receiving vehicle engine. There was no physical way to reach the mixture screws on the carburetor once it was installed onto the engine in the vehicle (Ford E-250 ClubWagon). This adapter was installed onto a 305 Chevy engine which I had configured onto a home made stand-alone test stand, complete with all components (radiator/alternator/battery/fuel supply etc). This adapter enabled me to test and adjust a 4 bbl Holley on a live 'sound' engine with plenty of open access space prior to installing it onto the engine of the receiving vehicle. The kit contained everything I needed to accomplish my goal. This kit was not used on an engine used in an operational vehicle, but I saw no reason it would not perform satisfactorily if that were to be the case.

Fit my Edelbrock Streetmaster intake perfectly and my 2 barrel Rochester carb mounted perfectly to the adapter plate as well BUT I had to cut an ear off so it wouldn't interfere with my high idle setup. The engine came out of a 1984 Impala with a 305 (5.0l) it's now in a 1955 Massey Harris 44 so I have PLENTY of h.p. so no need for 4 barrel and waisted fuel. All in all it's not bad for the price and a 5 minute mod with an angle grinder. *Edit* I've recently learned that the ear I cut off is for a Carter (Ford) carb with a larger body so if that's what you're using it for you should have no issues.
