Can anyone help to identify the manufacture date for my 270?
The engine no. is 270I22734. I have it in a 1942 WW2 CCW-353 truck - correct engine for truck, but not original.
The block casting no. is 2135412, which puts it between 46-54 as far as I can tell, but I'd like to nail it down to the year.
I've tried several no. crunchers but they either operate on vehicle, not engine no.s ; or Chev not GMC.
Thanks!
