Well a bit of bad news. The motor I got was bunk. I am trying to work out warranty info with the seller. Turns out, the front of the head is pretty much broken off. Cams and head are destroyed
Good news is, the mounts are completely done and with the SC400 oil pan, clearance for the diff and panhard are not a problem. Now I just have to wait for a new motor. Meanwhile I will work on the exhaust.
