Re: One for the small block decoders
Hey Grump, You got everything you need there to positively identify your block.
VI208TBC
3970010
L10
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
