Re: 435 sequential vin engine pads-comments?

So am I allowed to say which one I think is real?

You may burst into flames. From my absolutely untrained eye and comparing to the collection of deemed "correct" '67 L71 pads in my library, I'll throw my dart towards 586 is correct.

didn't you get the hint? we're talking wooden nickels. why would they be on a Corvette pad? don't get discouraged - its a great hobby. go to meets - do your own investigation, make your own library of pads and if you ever want to buy a BB 67, get help from an expert. but ultimately, its your money. but i'll say it again - its a great hobby!

So what you mean Roy, is of the 3754 built, there are only 8917 left, correct?

Re: 435 sequential vin engine pads-comments?

I'm curious as to how anyone would happen to come across three consecutive engine numbers and to be able to take pictures of them. Am I missing something here because the odds against finding a consecutive three out of the thousands either factory marked or restamped are astronomical.

So 1 of the 3 is real?

I'm beginning to wonder if this hobby is for me...

Will,
If you have the passion for these cars then yes, this hobby is for you. As others have stated, take your time, go to meets and get involved. You will meet lots of great people willing to steer you in the right direction. Never buy on impulse and always seek the opinion of a pro before you spend you money. I would rather pay over market value for a car with no issues vs. a car that appears to be a deal with "skeletons in the closet"

Re: 435 sequential vin engine pads-comments?

It has taken years of me collecting photos of vin pads and this is the first time I've come across 3 big blocks in a row like that. I wasn't looking for it, I just stumbled across it. I do have photos of xx630(2/2),xx632(2/16),xx633(2/15?),xx634(2/10-BB),xx636(2/15), but one is a big block and photos of a few of them aren't very good. The pad surface on the small blocks look much more as I would expect. I don't like the surfaces of any of those 435s.

Regarding odds of 3 435s in a row. If I recall probability correctly, there is a 2% chance of 3 435s in a row if they were built randomly.

I don't like any of the pad stampings. More to Roys point. No way that the 3 engines would have 3 different build dates & so far apart built one after another.

Yes Jim! The 435'S are like the FI Corvettes the tended to multiply like the loves & fishes after a few years of being released from the factory & all have MATCHING #'S & THE REAL DEAL

Re: 435 sequential vin engine pads-comments?

.... I would be absolutely shocked to find that three 435’s in a row were ever built.

Then I would want to know how in the world since engines were racked as they came in and pulled as they were needed, how three cars built together ended up with engines that were in my opinion from three different racks, which had arrived in three different months. .....

Roy --- a little further on the subject of racks. GM Canada shipping records for 1969 MY show 4 consecutive BB VINs: 9S706395 thru #6398, then a gap (ie. a non-Canada car), then #6400. Allows us a rare snapshot of the production line at a particular moment.

#6395 is L68; # 6396 is L68 w/K66; #6397 is L89; #6398 is L36 w/K66; [skip #6399]; #6400 is an L71. So were these 5 different 427's on 5 different racks, because of the assembly stamp suffix ?

Did I mention that Canadians were suckers for big blocks that year ?

In 1969 was St. Louis running 2 shifts to accomodate the demand for almost 39,000 cars with an extended production year ? Five minutes per completed car, or ?

Agree with you on the wide spread on engine assembly dates, but three L71's in a row ?? Personally, I'd never say never.

Sixteen months of production, about 2,500 cars per month, about 587 cars a week, little over 113 cars a day or 14 cars per hour, based on eight hours a day, five days a week production.

Dick -

St. Louis ran two shifts per day from 1963 on.

Dick,

I think it was closer to around seven jobs per hour for the late C2/early C3 cars.

From the conversations I had with both Flint and Tonawanda workers the different engine types (ei: suffix codes) were built in batches at both plants. Thus I would expect each suffix code to have its own rack, but John Hinckley could tell us more.
