For the first 50 or so 66 chasses delivered (i.e. 253-310), what do we know of the build dates on the ID tags on those AUTOMATIC transmissions?  Does anyone have a tag photo from one of these transmissions, or what was stamped on one???

In full disclosure it's mine; taken out of my car as itis incorrect (naturally). "OEM Paxton Supercharger 2 1/8" Fuel Pressure Gauge 0-15# circa late 70s. Condition is "Used".-- 2 ⅛” PAXTON fuel pressure gauge, 0-15 psi, of unknown vintage (but older than 37 years of known ownership) taken out of a '66 GT350 it was incorrect for.  Displays the three red 'V' sparrows after 'PAXTON'.  Face is bright and defect free.  Reads accurately; S-W 240A fuel pump was bench tested for 5 psi, an under-hood gauge read 5 psi, and this gauge read 5 psi when all were installed together in the car. The needle rests a needle-width above zero with no pressure applied.  The only fault I can see is found under a good light at the 3 o’clock position along a 12 mm arc, about 0.5 mm wide. There is a bubble in the original paint and some veining growing along the edge (see photo).  On the back, there is some discoloration of the thin nickel(?) plating from handling.  If you stick the port up your nose it smells of gas(oline).  If your head is up your bumm, you'll smell gas as well.  It has been always installed old-school with a thin copper pipette line directly to a carburetor or fuel line.  THERE IS NO PROVISION FOR AN INTERNAL LIGHT SOURCE IN THIS GAUGE!!! "

In photos, the 013 DLR plates gather so much attention, but the Atzbach collection had a 1B 4101 plate also attributed to the organization.  What was the difference(s) in their application(s)?

I have my suspicions,  but would like a knowledgable answer.

 

Given recent discussion of leaky C4 oil pans:
 

I’ve constantly got a leak from the pan gasket.

I’ve removed the pan and straightened the ridge along the bolt holes, refitted a cork gasket and torqued the bolts to 15 foot pounds.

The leak continues.

I’ve don’t it 3 times and still leaks.

I welcome suggestions as to what can fix this problem.

Acknowledging an aluminum pan for a C4 transmission is not original, is there a fully finned no-name pan out there, or one with enough meat so any raised name can be ball milled down to remove the name (or just leave the finned remnants there of)?

I have loved my C7FE le mans cam with standard transmission, bu I doubt the levels of vacuum would work well with a C4 hipo automatic.  I was pleased with the hydraulic hipo cam profile with my cruiser automatics, bu missed the seriousness of the Le Mans.  What has been the group's experience running something more radical than a hipo cam with an automatic?... brand... approx spec, please.
