I went to the past posts and I didn't see an answer to my question so here goes:

Pulled a 350 out of a 83 Chevy pick up yesterday.

Looking at the casting codes, this is what I found and what I know.
3970014- 70-73
Low power 200
High Power 300
Main caps 2/4
LA Built Camaro
Cast in Tonawanda, eigth hour of a ten hour shift

Now is the hard part, this is cast on the passenger side rear

T7CON/2
What does this mean??
