    Something is missing...and sad to say it is that you won't pass smog without all that stuff hooked up[​IMG].

    Yes it will work. You will just have to play around with vacume lines to get right.

    I did the same thing to my 85 with a 305 motor and 700R4 tranny. All I did was get a non-computorized distributor from a 1979 4x4 and basically rebuilt it putting in a new module,stator, and new vac advance unit. Then located the ECM behind the glove box and unplugged it. Installed new distributor, slapped on new carb. There was an issue with the timing and I had to advance or retard the timing but I don't remember which way. Since you may have to pass a smog test down the road I would try to leave the vaccum lines and hoses connected where possible. Also there is a fuel tank vent hose running from the charcoal cannister that connects to your present carb (I think that is where it was connected) that shoud not be blocked off. I routed mine back into the cannister. I was told by another member that blocking the vent hose or leaving it disconnected could be very unsafe. Good luck
