Need a afb carb expert on the numbers, Dom

[Domenic T.]

I bought a restored 78 Chysler. Every thing was done and it was my friends.
Trouble is that when they new engine in they changed it from a 2 to a 4 carb. My friend is a smog guy and said to leave the keys. Went back and he said the new Edelbrock was WAY to rich. I told hom I would re-jet it, and he said a Edelbrock NEVER passed smog.
So I went to my shelves to get a Q-jet and adapter and found 3 AFB's to replace the new Edelbrock.
Here are the numbers:
#1 3856S and has a choke of manifold heat spring choke.
#2 3351S with a AL1 underv the #'s and has a exhaust manifold choke.
#3 G7 4401S with a secondary flap and a manifold heat spring choke.
Any help on what I have would be great as I have to rebuild 1 and rid the Edelbrock.

Greg,
Thanks a whole bunch. Had these on the shelf for mega years and now will have to build one for a 318 Labaron.

I did something very similar when I removed the 2 barrel on my 76 Dodge PU with a 360 and installed a 4639SA with matching intake from a 1970 Dodge 340. The engine ran too rich and know amount of adjustment seemed to help. I contacted Mike’s Carburetor and ordered new jets and it made a big improvement in the engine. The old jets were .089 and I installed .086 it was a pretty cheap fix. Mike’s phone number is 888-689-9758

Bob,
Exactly what I told the smog guy and he said NO, as long as it's a Edelbrok it won't pass! That's crazy.
The engine in my 78 is a 318 and it had a 2 barrel on it. when the car was restored they did the Edelbrok and carb.
The smog guy is somewhat of a friend because we sent him many cars and he was part owner in a airplane near ours. He said a afb would pass jetted correctly. I won't rebuild until I talk to him.
I just can't see why I cant re-jet it?
