Fought me tooth and nail but engine is bolted down

Wow, seeing your pictures brings back memories of when I stuffed the Vortec 454 into my 1980 GP. You're at an exciting point right now; keep up the good work!

I tried to post the picture of the harness but that picture had overruled my attempts so I deleted the picture but it reappeared. My pc is possessed and it needs an exorcism so if anyone has a link to one please let me know....😒

Well got the cross memeber mounted and the drive shaft measured and dropped off. Wont be able to work on car tell sunday but plan is to hopefully stab distributor plugs wires cap and rotor and move the battery box from driver side to passenger side on sunday morning after work. Rhen see about scrubbing all the aluminum brackets to try to get them clean before I install all of them hoping I get lucky and the thread fittings from power steering pump will screw into the pontiacs steering box. Then I got to hopefully figure out how to get the 98 yukons ac compressor to work in the car as well I dont think they sell a harness to convert from pontiacs hire to the newer harness if they do what the part number or what did you all do
