chevy block suffix code help???

this code was the one stamped on the block in front of the passenger side head. the code is C7A103588...there was another beside it 12UTB7. can anyone tell me if that means it is a 350 or a 305 and year model the engine is?

you need the casting number on the back of the engine. those numbers there dont mean much. just where and when i was made. the casting number will tell you more

Yep, the one on the back is what you need, it will tell you the year and all that good stuff.
