How do I absolutley know if my 67 originally had a 350?
My Cowl tag said that my 67 had a V8, according to it being 67-12437. Above that is 09E showing made in 5th week of Sept and NOR. I saw some site that said the Norwood Ohio Plant didn't show that the car on the Cowl tag would have been a SS 350 until October 67. It said on location M option info (4) if it had a P then it would have been a SS 350 and showed on the LOS tags but not on the NOR tags until OCT 67, so it is possible that my car could be a SS with orig 350 just not imprinted on my cowl tag due to it being made the 5th week of Sept 67. Any thoughts??

If I'm understanding you correctly, your confusing the explanation of the 12437 on the trim tag with the VIN tag. The CRG website explains the differences like this:
12337 VIN vs 12437 Cowl Tag Code
Though it looks very similar to the first five digits of the VIN, the body style code on the Fisher Body cowl tag did not have the same meaning. Fisher Body didn't need the type of engine coded on the cowl tag, and so stamped the 3rd digit of the Fisher style code with a different meaning than the 3rd digit of the VIN.The 3rd digit of the VIN identifies which engine (L6 or V8) the car had from the factory. A VIN engine digit of 3 indicates a L6 engine, while a VIN engine digit of 4 indicates a V8 engine.
The cowl tags for 1967 Camaros were stamped with a style code of 12x37 or 12x67, where the x was set to 4 for standard interior or 6 for custom interior. All 1968-69 Camaros (L6 or V8) had a style code of 12437 or 12467 on the cowl tag - the 3rd digit of the firewall style number for these two years was fixed to 4 and effectively had no meaning.
I believe this is what you're referencing, also found the CRG site.
The 4P code was not used at the start of production at either the Van Nuys plant or the Norwood plant.
Van Nuys started using the 4P code on the SS350 cars in September, but Norwood didn't start using the 4P code until October. Early Van Nuys SS350 cars and Norwood SS350 cars built before October will not have the 4P code to verify that they are SS's.
The 4P code can indicate either a SS350 or a L30/M20. Usage of the 4P code with the L30/M20 is believed to have started in the late December 1966 / January 1967 timeframe.
The very first 1967 Z28's and L78's were also coded 4P; the 4L and 4K codes were then used on the remainder of 1967 Z28 and L78 production.
The lack of a 4P, 4L, 4N, or 4K code indicates the car originally had a 327 (assuming the car had a V8, as indicated by the VIN). The only exception is the early SS350's noted above.
While it is possible the car came with a 350 engine, the odds are more in favor that it had a 327. I'm assuming the car no longer has its original engine where the engine code could be used to verify what was installed at the factory. If not, unless you have the Warranty Protect-O-Plate for the car, I'm not sure how you can definitely determine what engine came in the car. Like mentioned above, a 12 bolt rear axle would be a clue.
