What are the biggest reasons the numbers DO NOT match?
Do you have a numbers matching car?
I'm "lightly" looking for a good deal on a shark for next winter's project. Something to wrench on when I get the bug.
I wasn't to concerned about the numbers matching.... but then I recently thought "why exactly DON'T the numbers match?".
So, if your numbers don't match... do you know why they don't match?

Yeah, I had taken the stock 3.08 peg leg rear out and installed a 4:11. Took out the M-20 4-speed and put in a M-22. Then took out the 454 LS5 motor, sold that for a paint job on the current project and built the 468 LS7 that is currently in the car.
Guess that pretty much took care of my numbers. :lol:

I don't have my original jack
My wheels are dated too late to be original to my car (although this is not a judged item)
I dont have the correctly numbered carb (a fairly rare item) for my car.
My AIR system is entirely missing, although the way ads seem to be written, the term "matching numbers" does not apply to missing parts. :lol:
Lots of nonoriginal and nonfactory style non-numbered or at least non "judged" parts.
The biggest "non numbers matching part" for most is NOM, but at least I appear to have my original engine. :) MJ
Actually, a lot of people would call my car "numbers matching" but I dont like to use the term.... :U

The most common thing is that someone would blow their engine and then replace it rather than rebuild it. A lot of the numbered parts were replaced with rebuilt parts from the parts store and their original core was traded in.

Because some Bubba decided my 72 needed a 305 :U . I have since rectified this situation by putting in a 383. :thumbs:

My title matches my VIN, but beyond that, all bets are off!
My suspicion is that a lot of engines suffered damage of one form or another. Lack of oil, lack of coolant, over-revved, scored bores, cracked blocks, etc... and they were replaced with one of the gazillions of Chevy V8's out there which is often simpler than going through more expensive machining on the old block.

Since they are performance sports cars designed for performance enthusiasts, many Hot Rodders :cool: have replaced the engine w/ a larger one.

Heck, my VIN# did not even match the number on my title on both my 71 and my 80. Very very common problem on vette VIN's. The "S" in the middle of the VIN gets misread as a "5" somewhere along the way and the only way you can fix it is to have a "fisical inspection" done by a law enforcement agent. I have had it done on both my 71 and 80.
As far the Non Original Motor, think about it, if your vette came with a base engine (L48, 270hp 350, etc) and it would cost you the same amount of money to refresh the lazy motor OR get something with more UMPH, what would you do? :thumbs: :steering:
My tranny is numbers matching, and most of the rest of the car is original.

How does the tranny VIN match the car VIN? I don't see these numbers matching at all on the TH350 I pulled from my car. Maybe that'll make me feel more inclined to sell it!
BTW: My engine matches...but I'm feeling like I'm in the minority here :smash:

Re: What are the biggest reasons the numbers DO NOT match? (page62)
When I bought my 69 T-Top I knew that the block was a CE replacement from 1970. The the codes on the intake and exhaust manifolds, as well as the carb, seemed to be correct. I wasn't concerned about matching numbers so I never gave it any thought. When I replaced the valve covers I saw that the heads were also correct so I assumed that the block had a defect and was replaced under warrenty.
Last fall I pulled the trans and found out that it's codes indicate that it is a 66 or 67 build Muncie. So now I go from thinking that the block was defective to realizing that some Bubba probably trashed this car in its early life.

Re: What are the biggest reasons the numbers DO NOT match? (6t9l4t6)
I'm in the same boat as 6t9l4t6. My car has original heads, intake, tranny, and rearend, but it's a CE block with a casting date one month later than the build of my car. From everything I've read, here's what happened when the car had a warranty replacement of the bottom end.
The dealer would go through the parts system and order a new short block from Chevy. He'd order it according to the original type of engine that is in the car. Chevy would ship a CE block to the dealer, who would then install the heads and other parts off the original engine (assuming they were not damaged as well).
So, somewhere in 1969 the original owner of my car blew the motor :eek: That's why my numbers don't match, it's all due to the 5/50 warranty. :D

Mark, my '79 definitely had the vin stamped into the transmission housing (a 4-speed ST-10).

From the windshield back my car is 95% correct. The numbers on my engine match...uhh but that's about it. :D

Yes they did in 1979. The identification code is stamped in a vertical surface on the passenger side. This code has six characters. The first is a letter that denotes the manufacturing plant. The second is a number representing the year. The third is a letter denoting the month. The third and fourth are numbers representing the day of the month. The final letter is either a "D" for day shift or "N" for night shift. The final eight digits of the vehicle VIN are stamped into the transmission case on the driver's side adjacent to the oil pan.

Basically I do with the exception of a GM high-torque mini-starter and a higher amperage alternator. Why? I do not drive my 1979 as aggressively as some owners.
The match is 10002.
