I am wondering if this carb is the original style for the 273 Commando. I am building a 360 to look like a 273 Commando-right down to the valve covers and correct breather. I am assuming this carb would fit an original 273 Commando air breather. Any feedback would be great. thanks Al. 1967 Hemi GTX 1969 Chrysler 300

Take off the Edelbrock nameplate, and you have a new carb that's also bigger than the 273 carb and more in line with a 360's needs. You may need to do a couple of things for linkage and choke. R.

An actual 273 single four AFB looks very unique, they also have the smaller air horn (unlike modern air horn AVS/Edelbrocks) so with a stock air cleaner you'll need a small dia air horn AFB.

How much would it cost the OP to have you do such a carb? Or the largest carb mentioned above? I am assuming the OP wants it to "look" original, but I don't believe he's talking about looking original to a concours judge. So what's the best way to go to feed that 360 and still keep it looking like a 273 to the casual bystander? Would it be possible to modify the stock air cleaner base to work with the later larger OD airhorns? R.

How difficult is it to find a "real" 273 carb? Finding one might take some searching How much would it cost the OP to have you do such a carb? Or the largest carb mentioned above? I will restore any customer supplied good core AFB to "like new" condition for $399.00. I can also build clones just like my Hemi clones which will have as much as 800 cfm, they are based on new style Edelbrock AVS carb bases with vintage 4 5/8" tops. This way you can still use your original air cleaner, all other stock parts fit as they should, you get a carb that looks and runs as good as a new one and uses readily available modern jets and rods. These are $599.00 plus shipping, built to order. I am assuming the OP wants it to "look" original, but I don't believe he's talking about looking original to a concours judge.

The clones I mentioned above Would it be possible to modify the stock air cleaner base to work with the later larger OD airhorns? Sure, anything can be hacked up, but I wouldn't do that to an original 273 air cleaner

They might be kind of small on the CFM's. Maybe 500? That carb in the ad? Read that might not look like the actual unit.

You'd think they'd use the best looking example in the picture, maybe they did. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
