Default strange casting


Never noticed this before I cleaned up my cast iron 63 intake manifold.
Anybody ever see missing characters in the casting like this?

That's one of the secret Bill Mitchell 7 cylinder Corvette engines. It went in the XP-7 pilot car.

Does your car have a permanent miss?

factoid (or urban legend...)... other than a power loss, you could disable either 5 or 7 and probably not notice it as they follows one another in the firing order

Seriously tho, I've never seen that...if somebody ground the characters off they did a damn fine job, but why ? Why the "I" in the phrase "Firing order" and the "7" in the digits ?

Isn't cast iron manufactured in a mold and doesn't the mold have the embossed characters already embedded in it ? It is a bit strange..

It will never run without FIR. Any redneck will tell you that.
Maybe the matching block is a 7 cylinder?

The short answer is that the #'s were soldered or glued on to the pattern & the I & 7 fell or got knocked off before the sand molds were made. It happens a lot if the letters & #'S are not cast in the pattern casting.

A person has to actually install the numbers/letters in the sand mold.
The old saying has always been to not buy a car built on Mon or Fri.
On Mon, workers are hung over from the weekend, and are prone to making mistakes.
On Fri, workers are in a rush to get off for the weekend, so they get in a hurry and get careless.
Obviously, your manifold was cast on a Mon or Fri.

Throw that car off the judging field! It was assembled by humans and
not restored as it came through the factory.

Probably cast early on Tuesday morning after a three day weekend.

As a young adult, I worked in this type environment for a few years. Saw plenty.
