Is the date code Feb. 13, 1967 the same as the other date codes on your car? More than likely the plant which produced your mom's car had leftover 66 manifolds. The 2bbl manifold (9784438) listed on the internet as correct for your 67 also list it as being correct for 66 326 engines.
I would say your car is numbers correct, there is a good chance the plant that produced your 67 only had 9782894 manifolds available.
That's odd, I never heard of a two barrel on a GTO before. Wasn't the Quadrajet mandatory equipment for the 67 GTO? I could almost buy into the "using of left over intake manifolds" argument if it was a Carter four barrel and your build date was January vice February. Is it possible this was a period dealer action to make your Mom's car more fuel economical? Maybe a special order car?
You're right a seemingly matching numbered engine and an original owner situation sure makes this a curious case.
I have 68 400 2bbl from a gto. It has the N crank, windage tray and all. I seen that there are production numbers with the 2bbl option. The guy I got the engine from (for free) said I know you want believe me but he pulled it out of his friends moms car when they scraped it after his friend totaled it 20+ years ago. He said that they bought the car new and never did a thing to the car but drive it.
it was called the econocmy option and i was only avaiblabe with a auto trans and the his/hers shifter.my mom bought the car oringaly in 3/67 from the dealership.i have some of the paper work from the deal.im just asking cause the motor was never tampered with until i pulled the car apart to start to restore it..im just askin if they heard of such a thing like this
I will have to look when I get to our home in St. Louis over the week end of the 8th I am in Dayton at our other home right now till then. I believe it has #13 heads, to bad there not 70's #13. But I'll pull the vin, block index, build dates on the block and heads, when I am there.
