1967 435 original paint on market place 119k
 

Not sure if that ad is legit, but regardless it's an obvious restamp even from the poor-quality FB photos. That is market for a green NOM driver that has some documentation it was actually built a 435.

A '67 435 with no paperwork and without the original engine could have been born anything. A '67 for sale on a big-name forum was advertised this week. It had all the right stuff a 435 should have, but the trim tag showed it was never a 435 with sidepipes. The green car may be pretty, but be careful. I have a good pad picture in my files.

Good Morning Tim. I never knew one could tell on a 67 Corvette by the trim tag if a car was a factory 435 or sidepipe car. Just trying to learn here. Thanks, Bill

----Can't remember, Tim, but doesn't a sidepipe body have to have been built at St. L factory? I also saw no reference to a build sheet on the tank which would help a lot. Even so,,, non original block at the very least!....Bill S

Trim tag tells if body was built at A.O. Smith or St. Louis.
A.O. Smith did not have the tooling to cut the slots in the birdcage for sidepipe mounting, so a sidepipe car HAS to have a St. Louis trim tag. 435 cars cannot be determined by trim tag, that is my opinion - there are folks more knowledgeable than I who say no 435 cars - and NO 427 cars for that matter - came out of A.O. Smith but I don't know how they can be SO sure. I believe some (very few) 427 bodies (remember there were four 427 options) were built in A.O. but final assembled in St. Louis.

Tim is using thoughtful logic... No AO Smith big blocks in '67 and no side pipes in AO Smith 65/66/67.

Trim tags are helpful. They can’t tell you for sure it’s a big block or sidepipe car, but they sure can tell you it isn’t optioned that way. Great comments above, guys.

I have never seen paperwork for a 1967 AO Smith big block, those tank stickers have Dow Smith noted. I've also never seen an original engine 427 with an AO Smith trim tag. That being said, maybe one is out there and will turn up someday. If so, it really needs to have the original engine or paperwork to be a no question AO Smith 1967 427.

Thanks to all of you who share info on this site. I have learned alot and appreciate it.
