John,
Here is another thing that is strange to me, although it means nothing to me in the sense of giving a crap. The heads are 3991492- They should be cast from 1969 thru 1972 or 73 and could be 1.94 or 2.02 and 1.50 or 1.60 (327 or 350) depending on the source of information. The cast dates on these heads are H-19-4 & B-25-5!! Beats the hell out of me, I have a fair amount of good literature and have not seen these being cast in that time period. The motor runs strong, have had it for years, going to freshen and paint it orange, putting it in my '68 Nova.
Damn, she is even prettier undressed!! :lol: :lol:
