Hello Vincent,
You did not answer the question for yesterday about getting the side window date codes. What have you found?

Re: Very possible

This car is # 1356 off assembly line,maybe thats why dates so close together?

Re: Cast,,Assembly,Body build date

Hello Vincent,
I have seen a very late 1970 base engine automatic engine. The car is owned by the original owner. The block was cast and the assembly the next day. It was possible for one day apart for the dates.

Thanks Drew I think that with the low prodution in 70,they were backed up in early 71 prodution,maybe thats why my car has these questionable things,do you agree

Re: Very possible

Block casting one day and engine assembly the next is in the NCRS archives as something that happened (Try searching ALL key words "John Hinckley engine assembly"). As I recall, it was a very tight schedule requiring three shifts a day to get it machined and assembled.

If you add to that long shot the assembly of that engine into a car in St. Louis the NEXT day, I have a little concern. This means that the engine(s) was overnighted to St. Louis by dedicated truck...it's possible, but it makes me wonder if the General would have allowed themselves to get in that position so early in the production year. It would seem like really bad production planning for GM.

Even if it was a case of an engine cratering on start-up, and a replacement having to be brought down from Flint, why wouldn't GM just push the car aside, and wait for an engine to be delivered normal schedule?

Re: Cast,,Assembly,Body build date

I have judged more than one flint block 73-77 cast and machined the same day. One to three days is the norm. In thease years more than two weeks is rarely seen.

Re: Cast,,Assembly,Body build date

Thanks for all feed back on this,I'm confident the motor is original to car,just have to figure out other ?'s about this car

But,

we don't have that high a degree of accuracy on determining when a given car was actually built (unless it was right on the first/last day of a month) because our birthday calculators all work based on interpolation. While some are more intelligent than others (factor in known holidays), I've yet to see one that knows all about assy line speed-up/slow-down episodes (often the focus of union grievances), temporary work stoppages, wild cat episodes, swing shift & authorized overtime, Etc.

So, I take most birthday calculations rather loosely and figure they're probably accurate +/- a couple of days...
