I agree with Patrick. I think I judged Terry's 1970 at Seven Springs for Duntov. I also did Bowtie for it somewhere--seem to remember that was indoors.

OK, I surrender. But if we get the chance I'll ask Dave B in Marlborough. I somehow had 1992 on my mind. I know I had some judging at 7-Springs, so I am on board for that much.

BTW: We are way off topic of the OP here.

Back to OP's question: about 5 years ago I studied 72 #13199, a very original base-motor automatic car. Intake manifold gaskets were the originals with GM on the tabs. (The heads had not been changed). It had one head cast M114 in the position that would normally designate a date.
The other was dated A 5 2

Mike, so we have blocks with M head with M why not a intake ? Jan would be about right time since my car was a late March 70 most casting are Feb 70 remember 70 started Jan 70 due to strikes, so a lot of things off a bit.
THANKS

In the letters I posted it did not state that the M code was restricted to blocks, it said "castings". I believe the M code was a newer version of the "X" that was used on castings in the 50's and 60's for the same purposes. I see no reason why it could not appear on an intake casting.
I also suspect that the numbers following the M may be Julian dates rather than calendar date.

Terry, This is the 70 Convertible I just bought, original owner original title 7,000 mile original rough paint pretty much virgin no damage
I am interested in Survivor , we talked about the carpet dye. I have a good number of questions re what I can / can not do to maintain
survivor. Service stuff has been replaced carb, alt, W pump and probably starter OK to put on dated original parts, Sokolowski has most.
OK spot paint lacquer, has roughly 10% paint repairs I should do right nose/hood. OK to degrease under hood. Valve covers and intake NEED paint- you seem the be the man that knows got a bit of time ? Much appreciated Bob 760 4130 363

You should get a good cadre of C3 judges at the Lake Tahoe Regional in September. Stop cleaning off all the originality and consider bringing your Corvette there for Flight Judging.

Terry, the yellow car is in Tennessee, so more likely out here late summer / fall. I am reading and re-reading about "rules" It was running terrible, so I am replacing things that have already been replaced plugs, wires, cap points,carb changing oil in auto trans so it is drivable. Repro dated wires, original correct cap
Otherwise I will do a chapter or regional flight judging and go from there. My blue 70 is in Calif
and almost ready- whole different program on that one fully restored by the book, that has been a education so this one is a real change of mind set. THANKS for your input. see you in July SC Bob

Something I might have missed in the conversation: Bob, you listed that as M 10 9, while in reality it is M109. Not trying to nit-pick here, but because it is not a casting date, but a mold run number, just trying to differentiate. FWIW

[Bob B.]

Re: intake 3965577 dated M 10 9 not possible? March 23 body

Correct M109, interesting 6th edition pg 105 M&JG M casting code M in lieu of a date OK I buy that, so there is no date
on the manifold just the M109 the factory did what the factory did, there is no exact normal

Same car has the odd telescoping antenna vin 7,502 try finding where THAT antenna came from- ! Tried every car and truck built in St Louis at that time and it doesn't match any antenna from anywhere- anybody have any idea what they are off of ? Apparently St Louis plant ran out of normal antennas so for some reason they used these odd telescoping antenna Thanks, enjoy the ride Bob
