So after a exhausted search I finally was able to purchase this 442 what is the best way to check its history. Does the GM heritage center provide that.
What are your thoughts the car had a frame off Rotis about 10 years ago. I've put about 200 hundred miles on it it needs very little work

Nice looking car. The deck lid wing on a convertible is totally wrong, though.

The VIN authenticates it as a real 4-4-2. However, absent paperwork, there is no ironclad way to prove it's a W-30 although there are many clues in how it's equipped that may rule it in or out.

What paperwork did it come with?

^^^ That's pretty impressive looking and there's a lot of good educational material there. But if you read it closely, it seems like Mr. Van Luven is proceeding from the assumption that it's a W-30 instead of providing proof that that's how it was originally equipped. "Proof"would include anything from the original selling dealer stating how the car was ordered
and then equipped from the factory. He hasn't given you anything that wasn't already on the car's cowl tag.

Thats NOT documentation. That is publicly available advertisement and sales stuff. It proves nothing. "Documentation" would be the original window sticker, salesman's order form, and build sheet. You have absolutely no proof it came from the factory as a W-30. Lots of Cutlass and 442's that are painted and decorated like a W-30 because they are more valuable when selling.

It would be like posting a restaurant menu and telling what great spaghetti they had. Unless you included a photo of what you were served, it wouldn't mean much. You could have eaten a cheeseburger.

Original broadcast card with W30 on it that matches the cowl tag would be good. Nice car though, congrats.

404438 are the correct W-30 "F" Heads. Further research is required to determine if the 261 head casting date is correct for a July 1970 built car.

One of the previous owners, seemed to waffle on its pedigree. At least that's how it struck me.

June 17th 2012, " I am the proud owner of a documented "70 W-30 Convertible. "

October 2nd 2012, " The number on the Oil Fill Tube is: 0365625 Do these numbers appear to be in the correct sequencing? Where else on the engine should I look to mastch the number on the Oil Fill Tube?"

Respectively, https://classicoldsmobile.com/forums...-w-30-a-50320/ and https://classicoldsmobile.com/forums...owl-tag-54727/

Have you thought about trying to reach out to him.

He had a total of 3 threads opened and 5 total posts. Then seemingly never to be heard from again. What strikes me was the first thread stating it was a W30 was not followed up with it being a W30 but just a 442 by the follow up thread... Nor did he ask anyone at least on the public side of this sight to verify W30...

That is a beautiful car and the color combo is perfect. I know everyone hates on the wing, especially on a Supreme, but I love it. I put a wing on my 72 back in the late 80's when I was in high school because they were rare when new and also just because I liked it. And my car was white on tan, just like yours.

Beautiful color combo. Whether it’s a true w30 is unknown it sounds like. Its n automatic car so it should have the tag on the trans.. however you can get those made so try to get some history on the car from prior owners if possible. Either way its a beauty..

....and it should have the car's VIN stamped into the side of the trans case. Another "source" of at least helping to determine what you may have.

Yes, and then check VIN derivative on trans against actual VIN and look for OW tag that doesn't look like a shiny new E-Bay purchase.

The font/stamping look on that OW tag doesn't really look "real"....when compared to known real tag pics. That's my initial impression based on your pics. Letters and numbers not the same as known real tags and other factors such as spacing and the look of the - (dash) marks is suspect.

Sequence of the numbers/letters may be incorrect as well.

Then again, I could be completely mistaken. Start looking at pics of known/real OW trans tags.

The OW tag starts with '70' not 'OW' like in your picture.

A few things that would concern me based on your tag.
  1. The order isn't correct.
  2. As Patton pointed out, the dashes are too big.
  3. On original tags, the stampings don't leave impressions around the digits like your tag.
  4. The area around the tag isn't factory as it's missing text, etc.
  5. The 'W' stamped on this particular tag isn't the same as known examples.
I would really look hard at original OW tags and compare them to the one on your car. Best of luck.

The broadcast card would be a pretty good pc of documentation if it's there? Some places they have been found: under back seat tucked in seat springs, behind plastic bucket seat backs and under carpeting if you're adventurous and handy.....

Yes, or a doctored one made to look vintage.

Rarity this is what an undeniably real one looks like. Backed by broadcast cards.

Post #1 here. https://classicoldsmobile.com/forums...ns-tag-146938/

As you can see the factory stamping is crisp, precise, and distinct. While yours is the complete opposite, as both 70Post and WTHIRTY1 both pointed out.

Besides the sequencing being incorrect, yours look like it was stamped on a soft surface that caused the stamping process to jump and distort as well as warp the plate itself.

Here below is a confirmed 1970 LS6 Chevelle tag.
