Boss looks to have E possibly D assembled 7-25 ?




That,s a D with a divot in the middle......




I don't know


But remember this , 69 model year assembly was schedule to start on 8/1/68 , this engine was assembled 6 days before that. I imagine that 68 model year production had already stopped, the only reason it would be a D is because the guy stamping it goofed, and it may have an E stamped over the D????
