Re: Engine block stampings
 

Bob:

If someone restamped the block, why wouldn't they have made it a couple days later than the casting date? My opinion would be that it's probably the real deal. Good luck and enjoy it, Ed

Re: Engine block stampings
 

Furthermore, its not a restamp, so there is your example of being cast and built the same day. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Re: Engine block stampings
 

I don't believe that anyone has said that it's a restamp - I'm just saying that the owner could look at the time code on the block and demonstrate how it makes sense that it's not a restamp. Of course, now that god has spoken - there's no need for a technical discussion.

Re: Engine block stampings
 

We (NCRS) have documented a number of Flint small-blocks that were cast and assembled on the same day, and MANY that were assembled the day after they were cast. The Saginaw Foundry sent 55,000 iron castings to Flint V-8 every day, and those dedicated GM trucks ran 24/7. Machining at Flint V-8 ran on three shifts, and both assembly lines ran on two shifts (170 per hour on Line 1, 130 per hour on Line 2).

Re: Engine block stampings
 

I agree Bob - I said that it was difficult ( as reinforced by the small number of instances that it happened) but not impossible. There were two Saginaw Foundries producing iron castings (one gray and the other ductile). Saginaw gray only ran two shifts and V8 blocks only ran at a rate of about 2500 molds per shift. The technical point is that you can tell by the casting clock if it was even possible for a specific case to make it to Flint in time for machining on the same day. For example, there's no way that an 11:00pm casting could get through processing and down to Flint for complete machining in one hour! I worked at Tonawanda, but traveled to our sister plants in St. Catherines and Saginaw quite a lot.

This is 'spot-on' per the date frames we see on the Deuces. I thought it was almost impossible for this tight of a date, but multiple Deuces have these tight dates. Now, we can tell rehits when the dates are not tight enough.

Re: Engine block stampings
 

Castings were not put into foundry inventory on a FIFO basis - there will always be legitimate blocks that have a large spread between cast date and machine date. Blocks that got set aside for allowable cosmetic welding as well as inventoried blocks sat around for quite a while. There will never, however, be second shift Saginaw castings that were assembled on the same day at Flint.

How many blocks were cast the day before, then, machined/stamped the next day while accidently stamping yesterdays date. https://www.yenko.net/ubbthreads/imag...mlins/hmmm.gif

That statement is very probable and could have more truth to it than we'll ever know!.
