Sounds like it was used in the same era as the 327. This 327 was also used in some mid to early Jeeps. If I'm not mistaken they were interchangable. Not to be confused with Chev 327 SB.
I do not remeber if they were the same block casting. I have a 327 in a 65 Jeep Wagoneer and parts from a Rambler 990 ( heads, 4barrel intake,bellhousing, and reground crank.
