Engine Assembled 1-7-70
The 350/270 engine for my 71 coupe was assembled in Flint Michigan 40years ago today. January 7,1971
The cylinder case had been cast on the twilight shift, December 31, 1970. The engine traveled to St. Louis and was installed in a car with a trim tag date of F14; January 14, 1971.
What I find interesting is that the dates on the engine parts that were assembled at Flint have mostly typical dates. (the intake date is pretty early). While a couple of parts seem to be too late for a January 7, 1971 engine until you remember that some parts of the engine were installed at St. Louis.
Here are a few parts and their dates:
Intake... H 27 0, (Aug 27, 1970)
Exhaust Manifolds... K 11, ( Nov 12, 1970) and L 23, Dec 23, 1970)
Heads... L 18 0, (Dec 18, 1970) and L 22 0, (Dec 22, 1970)
Carburetor... 0071, (7th day of 1971)
Starter... 1 A 55, (Jan. 1971)
Alternator... 1 A 7, (Jan. 7, 1971)
Distributor... 0 M 16, (Dec. 16, 1970)
Fan Clutch... 9 15 70, (Sept. 15, 1970)

Mine is in the shop today getting rid of the 2:1:2 exhaust and going to true duals. A birthday present to her to let her breath.

Thanks for the replies.
I, too, have always thought it was neat that the foundry worked on New Years eve. I believe it has something to do with how the blast furnaces were used.
Although the 'parts' have been off the engine, the engine itself hasn't been apart. It has just a tick over 46K miles.
I'm thinking about posting some more dates for it's trim-tag birthday next week.
I find it interesting that many of the parts have dates VERY close to the assembly date which indicates that there were not large stockpiles of parts at St. Louis and that the parts were moved very quickly from were they were produced to St. Louis and installed on the line.

These pictures are from about 2002.

The closest to St. Louis would be US Steel in Granite City.
The blast furnaces there produce molted iron in the range of 2000-3000 tons per day/furnace primarily for steel production.
The iron for foundries would have been cast into "piglets" for easy shipping to the foundry.
Pig iron was made made using a Pig Casting Machine that was a continuous conveyor containing a series of small block molds.
Molton iron was poured into a tundish that fed each mold as it passed the pouring spout.
The filled molds were cooled as they moved down through the machine and solid blocks of iron were knocked out at the end of the line for shipping.
The foundries would have to bring the iron block back to a molten state to cast the various engine blocks.
Unfortunately there are not too many of these casting machines left in operation. The last one I worked on was in Dofasco back in the 80's.
The whole process from feeding iron ore into a blast furnace to casting an engine block is very interesting.
Thanks VERY much for the information. I didn't know just how the furnaces and foundries worked or even if they were the same place.
I worked for the summer of 1964 at the Bethlehem Steel Plant in Sparrows Point Maryland. I'd see the furnaces from a distance but never got close to them; I worked in a tin mill. Bethlehem was a big business then. I believe they hired about 4000 summer employees. I made such good money that I was able to buy a new 64 Impala Convertible 327/300 4-speed with what I earned and saved. Very good days!

Here's a question that I've always wondered about...was there a cutover period for engines the same as for the car build? Asked another way, did they stop building engines then retool and start again for the next year?
I need to search my '70 for all this info too!
Have fun!
