GM used to send these out to anyone requesting, but I heard that this is no longer the case. I got mine for 1969 and I'm sure there are loads guys here with the 1972 version. Maybe someone can send you a copy of the page you need. -BA

Lmc truck shows your code so it indeed is a truck motor.

You'll need to check the date code on the block. Look here for a few pics of where to look.

Thanks for your replies.

WiL, Maybe I can find a pdf or something on the internet. Are there some words between CHEVROLET and TRUCKS or is this like a look-up reference as in 'Truck Data Book', Section 'Chevrolet', sub-section 'Trucks', sub-sub-section '1972'?

Geezer, That lmctruck link is handy. And, btw, the engine is definitely 1972.

To anyone, Does anyone have a copy of the 1972 truck info to be found in the Truck Data Book?
