66 engine assy. date / car production date

[E S.]

Hi- Did not see anything on this in the TIMJG, but what is the "accepted" window between engine assy. date, and vehicle production date ? ( my 66 is pretty close)
Thanks

Hi E.J. - pretty sure engine assembly date s/n/b greater than 6 months prior to the ~vehicle production date...

But, are you looking for the answer to the other side of that question?
How close to the ~vehicle production date can the engine assembly date be?
In other words, what's the fastest transit time for a completed engine from Flint or Tonawanda to St. Louis in 1965/1966?
dunno that one...interesting question if that is what you are asking.

Re: 66 engine assy. date / car production date

E.J. - My Nov 65 built BB engine is a mere three (3) dayz between engine assembly and vehicle build date.
In the past, I've checked about the dating possibilities...
JohnZ replied: "That is pretty close, although not impossible."
Verne Frantz: "A 3 day lead is not that typical but I have seen it many times."
I've also seen several similar online threads, confirming these close dates.

Re: 66 engine assy. date / car production date

Mark and Jack- thanks for the replies-I was concerned, because I had read a post that indicated that 3 days between engine assembly and vehicle production date was not possible.
My 66 also is 3 days- Good to know there are others!
(BTW, my block cast is I25 (Sept 2)
Thanks again

WOW E.J., your trans is Monday Oct 18 and your differential is also Tuesday Oct 19 - same as your BB assy. date...
pretty special week there for your car!

Re: 66 engine assy. date / car production date

Thank you E.J. and Jack for posting this info.

I've always been concerned with the close spread between my L36's Tonawanda engine assembly date of T1126IL and my car's final production date of December 1st, 1965. And I was worried about a 5 day spread! So these blocks were trucked to St. Louis?

Re: 66 engine assy. date / car production date

Mark- Yes- I guess things kinda "fell into place"-They were assembling my motor many miles away (How far is it from Tonawanda NY to St.Louis Mo.?) a mere 3 days before the car was shipped out the door!! They apparently did not cut too many corners, as car is still pretty much the way it left the factory.
Thanks

Re: 66 engine assy. date / car production date

Mike- Good question! I do not have the answer to that, but I am sure someone on this forum does. (Also, these would be completely assembled engines- not just "blocks"- correct?) Interesting....

Re: 66 engine assy. date / car production date

MIKE: Back in 2010, you once posted your casting date being I-22-5... I took note, because mine is EXACTLY the same.
Others have affirmed that this spread was typical for Big Blocks of the era (different for small blocks).

E.J.- Indeed, engines were occasionally trucked in (instead of the traditional rail cars).

Re: 66 engine assy. date / car production date

E.J. and Jack,

I've read somewhere in a prior thread that Tonawanda also trucked assembled engines to St. Louis. How else could your 3 day spread be explained? I can't find this really good thread that got into the subject "First one - last one off the truck" and how these engines were shuffled into the assembly line. I'm still searching. Anybody know this one?

Was the VIN stamped later onto the engine pad in St. Louis?

Jack, I've put together a short list of very close 427 engine "cousins" compared to mine. All 4 cars are within 8 days of each other's production dates and all 4 have the same 2 month spread between engine casting and assembly dates. I could send it to you and E.J if you guys want it. Kinda interesting. Mike

Mike- THANX for that very kind offer... I'll shoot you an email via the forum.
