October 6, 1969 date code I believe on the distibutor. So it appears to be an early 70 model year 455 from a big boat Buick donor car. However it looks like March 19, 1970 date coded heads. What is the date code on the front of the intake manifold?
Jim's correct its an extremely early 70s distributor. 1111984 = 1112027, 455-4 Buick Motor Division Information Bulletin #70-I-67, March 27, 1970. A revision to the Sept. 1969 printing of the 1970 Chassis Service Manual.
