Idle went nuts.

Alrighty, got her pulled. I mounted the chain at the rear lower head bolt hole and used a hole for the power steering pump mount in front. With the front jacked up, it came out without even removing the hood.

AND... a friend and fellow FABO member (and one of the most generous guys I know - his handle is IW378) is hooking me up with a spare engine he pulled from his 1968 Valiant when he swapped for a V8 so I can drive the car during the rebuild!

Thanks to everyone for the help. I'll be doing a ton of research and will surely be back with more slant six questions during the rebuild.
