I have an inline 6 that I'm having a problem identifying. It came out of a 57 wagon and the ser # is "Tb07A". The references I have do not show anything close to this code. I would greatly appreciate any info or help on this engines id.
Hi Michael
Are you sure it's not T 6 07A ?
If it is, then as per this:
https://chevy.oldcarmanualproject.com/models/engine.htm#54eng (scroll to the bottom)
it's a regular 235 six for a 3 speed manual transmission made in Tonawanda on June 7th.

@ole-olson If the b is a 6 then that would be it. It did came out of a 57 but I wasn't sure as it has been rebuilt and has a different valve cover on it. Here
is the exact ser#.
I've never seen anything but capitol letters so I'd wager that's a 6.

I think that is a 6 not b. The other question I have is why does the A on the end look to be stamped differently.

@michael-davis I have a 1954 261 engine that was a crate engine first used in a 1940 school bus. The installer stamped the 1940 serial number on the block. If you tell us the casting number, we can identify the engine. Or look on web page: . Good luck, Lou
@anthony-williamson The "A" was stamped at a different time. It signifies a "Regular" 6 cyl going into a 15-21-2400, meaning a 150, 210 or Bel Air. The other suffix for a "Regular" 6 cyl is "AD" meaning a heavy duty clutch.
