So first off I pulled off the front clip and disconnected everything from the old motor. A sawzall was handy for the old exhaust!
Next, the old motor comes out... did you disconnect the driveshaft?
By the way, I don't care what people say, I think those "coolant drain ports" in the block are there to make hex keys round! (ask me why I think this!)
The old motor out! I don't know if you can see this, but the front motor mounts were probably the originals! (Okay, probably not, but they REALLY looked like it. I could kill the "mechanic" who put this motor in!)
As this setup has a 3 on the tree tranny (converted to floor shift by me) I dumped the driveshaft along with the motor. The tranny will be replaced by an SM420 and I might be installing a divorced Rockwell 221 t-case when things go back in (if there's enough $$$), but that's another thread.
40 year-old dirt and grease, YUM! Luckily I have a pressure washer and a few different cleaning agents!
And now the new stuff can begin!
