Getting a updated drive train. 1) 3800 Buick Engine - Getting a different motor 2) 4L60 GM - Rebuilt transmission 3) Atlas 3.8 - Transfer case 4) PCM Wiring and Bench Harness - Basically that 5) Profit . 1) 3800 GM (Buick) Hey it fits......up until this point, i thought it would fit, i took measurement, but...... . There about were it will ruffly sit. I still have to re-gasket it. I don't mind going through the motor, it give me a good base line of where everything is at. The old water pump looked new, but the outside it look like it has been setting a while, ~10 years I know that this is TRUE.... plus, Dex-cool still in the bottom of engine. (eww orange stuff, i hate it) . . Oil Filter Adapter - see below.... Superchager - [X] order some parts - insert thing and some PAG, stinky oil Wiring Harness - (see pic) Stip out unneeded wires and sensors that will not be use. Move the VSS towards the transmission stuff. Much better for a RWD vs a FWD Move the batter cable out to a much better spot. Inspect it and re-wrap it. Cause I easily can test each wire to it known spot, (Its almost 20 years old) . . . ...more coming... .
