Hi
I have bought a 454 and it have been in a "Truck" before, I dont know what kind of truck but I have the VIN on the block.
Do you guys know where I can decode it so I will be able to see where my engine have been before.

VIN: C4Z139080

C4Z139080

C - Chevrolet Truck Division of GM
4 - Model year ends in 4, 1974; 1984=E, 1994=N
Z - Assembly Plant is Los Angeles,CA
139080 - Production seq no, started at 1000001 and went up. 39,080 truck order built at LA for 1974 model year.

fyi-El Camino's were not trucks.

So the VIN does not tell what kind of truck it have been in.
What kind of trucks was built at the Assembly Plant is Los Angeles,CA?

"If you're under control, you're not going fast enough"

If you can find the engine appplication code I can tell what type truck(s) and the engine RPO.

That should be stamped next to the VIN derivative on the front edge of block. If its not there, look for a small pad above the timing cover, many trucks have it stamped there.

LA built pickups, Blazers, etc.

Which type of trucks is Chevy 3/4 and 1 ton FWD trucks?

------------------
"If you're under control, you're not going fast enough"

Light duty pickup truck. Not a "big truck".
and not a "truck" (tall deck) block.

FWD - Four Wheel Drive
