Mr. Gasket 1933 Carb Adapter

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 used this to install 4 barrel Holley double pumper carburetor to a 2 barrel manifold on a 1976 Jeep 304 v8 it worked great lots more power!

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

The mounting plate and gasket worked well.

Exelente vendedor atento y era lo que buscaba lo recomiendo cómo vendedor

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.

When I received these, both of the plastic protectors were yellow with age and opened. As the price was exceedingly low, I could overlook this. When I went to install one adapter, I found the SAE allen bolts had been changed to metric and some thread damage was apparent like someone had tried to install them. I went and bought the correct bolts and all is well. The product is great and shipping was on time. And yes, I would buy again from this vendor.
