explain these VIN's please - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am trying to decode these vins but I have a book for engines in cars and these seem to be truck engines.

They are 350 blocks.
They both have 3970010 on the back of the block.

The first one is V0419TBD
it is a motor from 1971

The 2nd one is V0325TBB
it is a motor from 1970

I am mostly curious as to the horsepower and torque ratings of these engines and whether or not they are four or two bolt mains.

Thanks guys.

The HP ratings for those engines are gross HP, ie. rated at the flywheel. Net HP (at the rearend) is 165 HP. They changed the rating system from gross to net from 1972 on.

how can u tell if the eng/trans are the original ones to the truck?

Thanks guys. Doesn't sound like I have some real stump pullers here

Oldskool: I think that the VIN on the cab should match up to the engine codes. Not absolutely positive on that though.

mine has V1208TBC on the front of the engine block?

that seems to be pretty straight forward. So it is a 1970 engine? Also is the 255 the hp rating? Thanks...
