Not trying to Argue.

Can you address the questions posed given your stated expertise?

This is from the camaro brochure.

So, you called a machinist who has determined that the brinell hardness reading is greater on later blocks? 😂

Do you know how silly that sounds? All you want to do is argue. PM me if you really have questions.

Quantitative hardness testing on a representative sample of blocks cast on specific dates would be the only way to draw conclusions. I lived this Phil - please don’t just be contrary. PM me if you have questions.

Perfect!

Now with that aside the Marc Dant post is instructive as to the discussion for those so inclined.

The brochure must refer to casting design enhancements. Class 30 cast iron for blocks was metallurgically unchanged.

Two apparent distinct and separate references.

One to a tougher block. The other to 4 bolt main caps.

That promo was written long before they even cast an 3970010 block which didn't show up until the last part of April, 1969. "Tougher" could just be referring to a design change where some part of the block was beefed up.

I don't have a dog in this hunt, so it really doesn't matter one way or another to me.

Phil, are you saying there is credible evidence that "The best blocks have both tin and nickel, and show two numbers: 010 and 020, which means the block has 10% tin and 20% nickel."???

I don't believe anyone disputes there were a lot of design changes. If you have some GM documentation on the percentage of tin and nickel, I would be interested in seeing it. Just post it.

Yes showing respect is uncomfortable.

Right now Nobody wants to take a position because they are hedging that I could be holding back.

Ball is in your court guys. You watched a member here openly mock me which is the normal progression of things as the flame war that started nearly 10 years ago continues.

Lynn you are a Lawyer. When one side makes a motion you are rule bound to reply.

You do not get to question me further on my submittal because absent a credible argument the other reply is “gee Phil we jumped to conclusions and we are sorry”.

A non reply on the other hand admits my position as the fact

OBJECTION !!! Badgering the witness, PHIL
NO ONE is going to reply because we are all sick and tired of your bullying, badgering insistence on being right.
It has become PAINFULLY obvious that you will not quit until others do and you can feel self justified that you WIN...
Silence is not winning, it's just the rest being tired of your tactics.



Are you holding back ????????????

If so, the cards are on the table and now it's YOUR turn to show your hand of aces. If you have credible, documented PROOF to back up all your conjecture and smoke, we're ALL waiting to see it.


If not, then it's well past time for you to agree to disagree and stop the badgering to get your way.

As an aside I have a detailed Early and later 010 design comparison changes for blocks in images... I can post here if there is interest.
