We have pulled the "real" boss 429 out and put the boss 460 in the 34, and I have found some #'s on the back of the block. The #'s are
OF 1 40983 Anyone care to guess????

A 70 boss?? I always thought it was a service block because it does'nt have the HP429 cast into it. Can you tell anything else by those #'s, and do they tell the date??? Wade
