Thank you very much for your replies to my last post. I have another question.
This 69 super cobra jet has the automatic and 4.30 axle. An expert looked at the car for a client and said that the block was not original. The car was born on 11-1-68. There are no numbers on the passenger side block, where you would see a "C6ME" or other number. The date code near the filter housing is _D30. The first letter is not readable. The car has extensive documention, build sheet, window sticker, marti, ect. which all list it as a drag pack cobra jet. The crank damper appears to be correct. The engine bay looks numbers matching, somebody went to a lot of expense to make it right.
Not sure what "the engine bay
looks number matching" means. They either are or are not - lots and lots of parts in there to check
Allot of these cars saw heavy usage (that's often why they were purcahsed) and engines didn't always make it
Did the blocks destined for the super assembly line typically have no block numbers or does the oil pan have to be removed to find the third webbing.
They would have all the "regular" numbers and stampings plus some additional ones normally
How would a judge determine if the block is correct? Please advise.
In a class that requires the numbers to match they would look for the casting numbers, date code and vin... then compare those with other block features that either match or don't match what would be expected for a 428CJ
In the classes where number matching is not required some major casting numbers are confirmed for the door tag confirmation section of the sheet. Organizations don't want cars with different colors, engines and transmissions (auto to four speed for example) taking home top prize
PS - subject was moved since it seemed to be more about numbers and features than judging
