Just as easy to go to a nice running 1406 Edelbrock 4 barrel with the electric choke.

Can use the Mr. Gasket 2 to 4 barrel adapter (20 bucks at your local Advanceautoparts store) on your lean burn manifold.

Also works on the '89 - '91 TBI intake manifolds too, need to redrill the 4 mount bolts to keep it on center.

1406 Edelbrock

tks but want to stay with 2bbl carb

Need the Edelbrock to Mopar throttle bracket adapter so the geometry of your throttle cable is right.

Also need the correct auto trans kickdown linkage and make sure that is adjusted correctly so you don't burn out your trans. Needs to be adjusted correctly!

Edelbrock #1481 bracket:

Blue bracket is for 2 bbl.
Red bracket is for 4 bbl.

These 2 barrels are from '69 and '70 318s.

Here is the Factory Holley 2 barrel off of a 1976 360 Dodge Truck:

I did this conversion years ago on a 318 Lean Burn and I can't recall having to replace the carb. I just used the electronic ignition retrofit kit and my parents drove off into the sunset.

It's been a lot of years but IIRC all I did was move the hose that went to the vacuum transducer on the computer to the distributor vacuum advance. But I'll admit, it's been a lot of years.

The Carter BBD shown in post 6 was commonly used on 318 small-blocks. It is fairly simple to work on, having adjustable "metering rods", which I think is similar to the very common Edelbrock 4 bbl of post 2 (descended from Carter AFB?). You can download a manual for the BBD on the web. The link has been posted many times. I don't know about the Holley 2 bbl of post 7, other than Holly carbs are considered better but more finicky to adjust. I think there is an aftermarket for them since some racing competitions require a 2 bbl.
