Quote from: J_Speegle on December 10, 2021, 05:18:45 PMWith all the sleuthing over the years has there even been a data base with cars actual build dates along with the corresponding "tag" dates for components like engine, trans, sheet metal. If not this could be an important look into Ford's practices. Problems etc. Of course on untouched "documented numbers matching cars". On the B2 forum they have found a few cars with blocks cast months before the car was built. What about components that are built a few days before car assy when parts become bottle necks in the system. A factory with a shortage of 351C 2V engines in 1970 might see engine tag assy dates real close to the car's assy. I have heard stories of the 351C 2V in 1970 that is why I mention this. My friend owns a 70 Mach1 H-code original paint interior etc survivor with the 2V Cleveland in it. Just had it built at Roush and pulled 330HP on the dyno with a holley 2V on it. Jack showed up saw the performance and asked what was in the engine(cam pistons), what was done to the heads and asked them to use an adapter and put a 4 V on it. Pulled a lot more HP out of that engine. The way the heads were rebuilt, new guides installed and the ports "flash" ported was really interesting as it was done on a high tech laser machine and it did the job real fast. That is why Roush's quoted price to build the engine was much less than other "old" tech engine shops in the area when dealing with the canted valves.Quote from: CharlesTurner on December 10, 2021, 02:13:12 PMQuote from: J_Speegle on December 10, 2021, 02:05:48 PM
Wasn't the plant in the south somewhere? Don't have that document handy at the moment

Thanks for the clarification. Knew you would rememberQuote from: Special Ed on December 10, 2021, 03:02:03 PM
I dont recall c6 trans tags being date coded but a trans serial# instead i thought so was c4 trans tags date coded as that tag is a B (not an 8 ) in front of c11 so was that trans a c8zp-b id #
Here is an example from a 68 Mustang Shows the month and day of month and printed in reverse from earlier 65-66 tags
