Factory 1967 C10 327 with no code on option sticker?
 

Hey guys, I’m looking at a pretty original 67 C10 Custom tomorrow that the owner says is a factory 327. He sent me a pic of the sticker in glovebox and that’s not listed as an option. Only power train option was a power glide. I asked if it was a 283 and he said he’s positive it’s a factory 327. Any thoughts?

If there is no engine listed on the SPID and the model number starts with CS it was a 250 truck, and if it starts with CE it’s a 283 truck.

This.

I'd also ask for the numbers stamped on the engine. IIRC "YS" is the suffix for '67 220HP 327 in truck.

I second checking the stamping on the block. When I bought my 67, seller advertised as 327. I checked the block and it was 283.

Where is the engine stamped?

Passenger side of the block in front of the head. Casting # is on the back of the block on the top of the casting where the tranny bolts on. Here is a link to help.
