Folks:

You can use the VIN decoder under "Tools" in the toolbar on this page.

Either way it won't help...it wasn't until '72 that the Corvette's VIN contained an engine code. The LS6 option wasn't available after the '71 model year. The LS5 was available after that.

Looks like you'll need the tank sticker or other documentation to verify the car.

Thanks Gunslinger,

There was something there Sundevil74, but I could not make it out!

What was the last year for the LS6?I thought 71 72?but then again I'm basing this off of the Chevelle.

1971 was the last year for the LS6. After that it was the LS5 or the LS4, depending on year.

Was it an LS6?  Did you buy it?

Yes, it is an LS6 and the guy will not sell it.  $20,000.00 for the one you found sounds cheap.  They were RARE and FAST!

I was thinking like Gurtz but ran across this site today. It appears that the LS6 Corvette is number 27 of the 50 fastest muscle cars. Now that surprised me.
