Pulling motor ONLY
X3 I just did this with my 67. I run a 727, so don't know if clearance is an issue, but I.................
removed the rear crossmember, lowered the rear of the engine, and removed all the 3/8 bolts from the transmission bell, leaving only the two 7/16 bottom bolts.
Then jack the rear back up and put the crossmember back in.
Stick a couple of 2x6's under the front pan area of the trans, and tighten a ratchet strap around. As you pull the engine, tighten it up to keep the trans up.
Don't forget to pull the converter bolts, and put a bent steel clip on the bottom of the bell to keep the converter from falling out.
On my 67, I didn't even remove the hood
