Re: 360 to th400 spader
That's correct. When AMC bought Jeep from Kaiser, there were lots of the old Buick/Olds/Cadillac, ("round top"), cased TH-400's in their inventory. When those were all used up, they switched to a case to fit the AMC engines without adaptor. My '76 Waggie had the AMC case. My '70 has the BOC. I suspect somewhere around '74 is when they switched.
