L10 is the casting date
L = December
1 = December 1st
0 = 1970
Your block was cast on December 1st 1970

3970010 in 1970(or 1971 see below) is a 350cid.

VI208TBC is V1208TBC
I's used for 1's is very common when found stamped on Blocks.
1208 = December 8th
Your Block was cast December 1st and assembled on December 8th in 1970.

Casting Date codes are the day, month and year they say they are, but Suffix codes go by Model Year. Your block is December of 1970 which is the 1971 Model Year. So when you look up TBC you have to do it for 1971.
In 1971 TBC = 350cid, 255hp, 350auto, LS9, 4bbl, 10,20 C or K
So you have a 1971MY 350 Truck motor.
Great price. BTW

Thanks ,I guess I was just not firing on all my cylinders yesterday ! Everything is checking out on what he told me and I saw the pictures of what was left of his truck ,It got sideways and he lost it into a tree . Check out how long he ran it by the looks of the carb it wasn't very long . oil looks brand new nice green antifreeze drained all over in the bed of my truck on the way home all new bronze freeze plugs ,etc,etc , I'll stick it on a stand and pull the valve covers and give it a once over and if everything looks good I'll fire it up and see what I've got .
