Also you need a regular electronic ignition distributor and then an external voltage reg for the alternator if you go carb. The nickel and dime stuff is what’s gets everyone.
Depends if the car already has it. Many already do from birth though adding one, just one more thing to add up, is cheap. So is the external outage regulator u less you just simply run a GM style 1 wire Alt.
I stayed with a carb in the old car. For you, since most things I had on hand, The cost was an intake, a AFB carb, air cleaner, electronic distributor and box and a Edelbrock electric fuel pump designed for a carb.
Gaskets and throttle arm adapter.
I myself just needed the intake & fuel pump. The rest I had already. For me it was cheap. Way before the cost of intakes nearly doubled.
