3932388 block casting # is '69 350/300hp. Tonawanda cast & built. Not sure what you mean with the I=? in the engine code. My guess is T=Tonawanda, 10=10th month assembly, 7=7th day. (If the code is T10I7HB, the I7=17th day. HB=Camaro 300 horse w/T350. J108 casting date code = October 10, 1968
Heads casting date code G98 = July 9, 1968
Head casting number is 3927186, not 8927186.
3927186 = 1969 350 all models. Either 194 or 202 intake valves. If these are Camaro heads, the valves are 202's.
Want to sell it?

I was told that it was thought to be a low mile Camaro engine transplanted to the Impala around the mid 80"s.
