Hey, I just bought a 1968 Corvette Tripower L71 project car, and I need some advice on what I should do with my engine. I thought the car was numbers matching because I was told it was a #matching restoration block. Does that mean numbers matching?
Also, if it is not matching, the engine is shot and will need a total rebuild. Should I just buy a new engine or rebuild it knowing that it is not numbers matching. Please give me some suggestions. Thank you
Some people want matching numbers and restoration to the extent where the car almost cannot be driven any more.. -Hey just think if i wear out that original clutch.. -or have to replace the power cable from the battery.. -And so on.
Personally i think that the value of the car is to drive it and if i need to change out some items to make it a "good ride" i will do so.
Well its easy for me to say who started of with a non matching mumbers, no tank-sticker car..
//Edit:
On the other hand i have a friend who has a all matching numbers 1966 C2 convertible who has replaced the 427 and manual gearbox with a 502 RamJet crateengine and a auto trans.
He likes the "hotrod" he created but still have the original engine and parts resting in the garage to follow the car in the future.

Technically it's numbers matching but to many collectors it's not. A "restoration block" is often a block which carries the correct casting number and date code which could have been installed in the car originally. A replica of the original. It should look and run exactly the same as the true original but will not fetch the same value as an original. Sounds like a restamp which someone was honest enough to inform you of?
So far as whether to buy another engine or rebuild this one, depends on what you want to do with the car. If judging is important to you a "restoration" block will fly in NCRS flight judging with only minor deductions for the stamp pad. A block with the wrong casting number is a big deduction. If originality or judging are not important, it's a matter of which is cheaper, a new engine or rebuild this one. Either way the car will not be accepted by collectors with an engine which is known to be a NOM.
The car has the tank sticker which states that it is a tripower corvette. Also the car has the correct casting numbers 3935439 block. How much does a correct engine hurt the value of the car?

If you paid top-dollar for a numbers-matching car, then you change the engine...yes, the resale value will go way down. Why did you buy a 'matching' car with a bumb engine????
...I thought the car was numbers matching because I was told it was a #matching restoration block...
Did you check the numbers?
...Does that mean numbers matching?...
No telling what that means. It might have meant something to the seller. It may mean absolutely nothing to everyone else.
...if it is not matching...Should I just buy a new engine or rebuild it knowing that it is not numbers matching...
You don't know yet whether it's matching or not. Jot down the two numbers stamped on the pad on the block at the front of the right head. With those two numbers, you can determine what you have. Once you know what you have, then you can decide what to do with it.

"Correct" is meaningful to the NCRS and possibly some subset of the collector market but generally is still considered to be a NOM to most collectors, therefore a much lower value.
IMO this makes as much sense as devaluing the car because the brake rotors were changed. Difference is the engine block carries a serial number which can be used to detect a replacement. The way the market works.
An authentic tank sticker provides evidence of how the car was built originally, used as evidence a matching numbers block may be the original though not proof. You may find buyers who will accept the tank sticker with a 'correct' but not original block.
It no longer has the block it was born with, so do whatever you wish with the engine that's in there. If you frag it, find another "matching" block and you'll still have exactly what you have now. No harm, no foul.
O ok. It does not state the optional heads on the tank sticker. It must be an L71. Thank you.
It's on your tank sticker. There is a column of option codes on the left side of the sticker. Look for 02L71AA or similar. Text descriptions of the various options are in the center section where you have found the 435hp citation.
