81 and 84 ECM are totally different. If you are going to convert to a carb you do not want to use an electric Q-jet for sure.

You know you can use a truck style tbi, the 87-89 chevy truck 350 tbi have the same connectors & you can use a better flowing intake.
Your in Ca. What about emission laws?

They make a tbi to 4bbl adaptor or you can use a tbi intake, Holley makes the one that I use on my 84. Look at the pictures on my profile.

You will never be smog legal in CA with a carburator. I wouldn't carb it if you plan on driving it on the street.

I replaced my CF induction with a holley projection TBI manifold and a 7.4L GB TB unit. With a blower hat 2.0 high I have .01 inch clearance.
I should have miiled the manifold top .125- .25 inch.

If you use a adapter plate (.25 in) you may want to consider a weiand low profile single plane manifold or a Edel performer DP if it is short enough with plate.
