need help with my 81!
I recently bought a '81 that is all original...but suffered some post nasty divorce injurys during the battle over custody....my main issue is the carb and intake were removed and are long gone, anyway ive sourced the carb and intake but hope somebody could post some close up pics regarding the hose an sensor hookups for a factory installation? I am unsure about what sensors go where on the intake most of all... Any help would be very appreciated!

There is a lot of assorted plumbing on an 81 intake. You do have a couple of temperature sensors to hook up, but far more vacuum hoses and switches. You might want to get an AIM ( assembly manual). It'll help give you an idea of all the parts involved.

As you stated the '81 was a one year only setup induction and ignition wise regarding the 'Vette...but was commonplace among the rest of the sbc powered GM cars of the early to mid '80's.

I hear ya...but IMO it would be much easier to figure out if someone here posted a pic of an assembled 81 with the air cleaner removed...ideally showing the details of the intake from the carb forward...lol!

The main components of that system are the carb, distributor, the computer module, the oxygen sensor, and wiring harness. Those need to be the correct part numbers (carb from another 'similar' GM vehicle may work the same) or I'm not sure they will all link when connected. If any one of the main components is 'different' or not compatible with the '81 computer, it won't work as intended. It will just default to a basic programming mode and run poorly (if at all).
