I believe a scarce few 327cid's were released in 4 bolt configuration from the Romulus Mi. plant.I can't prove it,find their applications nor find the evidence that I saw to prove it,but have seen a few of them in my life and fully believe they were not modified after the fact.

Rick, what were those 4bolt 327s in? Or, what year were they from? I once had someone insist his 69 327 was a 4bolt.
