My 69 CST20 came factory equipped with the optional 350 small block but is not the typical LS9. It shows LS8 350 MD. Wondering if that stands for medium duty (?) The block stamped code on the passenger side face is WH Which for whatever reason is not listed in the ID guide I have. Do you any of you have any idea what is different about the LS8. From the standard 350 in 1969?
