I am in the progess of of doing my first engine swap and failed to propperly tag everything. I have some pics and was hoping some one could help me get the last few minor things hooked back up with them.

INFO: the motor is a 327 with 350 heads and intake and is going in a 1982 Chevy K20 3/4 ton. I dont know what the carb came off of but I know it is quadra jet, Rochester carb and Believe it is a factory carb. It is quite similiar to the one that was on the 350 originally in the truck.

First pic is the back of the carb and intake. I dont know what gos hooked to the line coming out of the back of the carb or what plugs into the hole in the back of the intake.


Second pic is a sensor(heat?) on the driver side head towards the front. What is it for, how important is it. I cant find anything that would obviously fit the plug.


Third pic is on the driver side, middle rite under the distrubiter. I found a plug that fits into it, it has two prongs but the previous 350 had a one prog hook up. I almost think the plug I have hooked to it belongs on the sensor in the previous pic on the head but I cant get it on, maybe just cause the header is in the way? What is circled thing, and what is it for?


I have been working on this thing in the little time I have had for the past 4 weeks, I would really like to get it wrapped up, some one please help
