Re: Block, Trans VIN match?
I went back and looked at all of the pictures of your car. NICE. My uncle bought a very very similar car when he got back from Vietnam. Same color. 327 with 4 speed. I don't remember if it was an L79 car (probably not) but it ran good.
I would not worry about the area on the transmission with the partial VIN stamp that looks a little odd. Maybe the casting mold just did not get completely filled, or whatever. That is probably the way it left the factory, since everything else looks normal.
Does anybody know about how many 1967 L79 Chevelles would have had the KM coded rear with 4.56 gears? Probably not very many.
Red 1967 Chevelle SS 396, 4 speed, 3.31 12 bolt posi, black bench seat interior, Bolero Red - long term restoration project
68 Camaro SS - 468 BBC, 781 heads, RPM Air Gap intake, Lakewood bellhousing, M21, BO coded 12 bolt - but 3.31 posi now. Old drag car, back on the street.
