I know this question has been asked often my apologies. I just cannot research these numbers.
I am selling a 235 engine that I have, and just need some more information.
It is stamped CON4 the I 6 6 on left side of distributor side. To the right of that is 3837004 which I believe is 55-57.
On the distributor plate it is stamped F920H.
Head is stamped 3836848 GM10. numbers on distributor side are B36 848 850. Thank u in advance.
