Re: value of a ZL 1 clone with a real ZL1 motor
It means I remember your engine being talked about on here recently.

Re: value of a ZL 1 clone with a real ZL1 motor
Thanks Rick,
A good read. So, if I read that correctly, it seems to be a legit L72 engine, just some guess work on weather the stamp is real or not. I wonder why no one pulled the head previously? In any case I will, and I will post some pics here as well when I resturn from the show. Like I said, 6k for a real running L72 aint bad, and will still be a cool motor for my Original 307 car! (Unless I put it in a LM1 King!  If the broach marks look good all the better, if not, oh well! Thanks, Rich

Re: value of a ZL 1 clone with a real ZL1 motor
I would have bought it for $6000 to. They were asking for $15000 when I looked at it.

Re: value of a ZL 1 clone with a real ZL1 motor
I know there are labs that can do some type of test to the metal to see "if the molecules below the surface have been compressed" by a prior stamping. I know there was a vette on Ebay within the last year that claimed to have had this done to the frame and block to prove there was no restamps...I believe it was a 67 L-88..not sure though. He had all the lab reports...maybe someone remembers the auction and you can contact the lab. But I know the FBI does it all the time to check removed serial numbers on guns. It may be worth it to prove originality..

Re: value of a ZL 1 clone with a real ZL1 motor
It can only be done once and the memory is removed from what I remember. So if the test comes up empty it proves nothing.

Re: value of a ZL 1 clone with a real ZL1 motor
I believe there are a couple fellows from a University in Utah that have come up with a procedure that can be done repeatedly and is not affected by the the old "one shot" test.

Re: value of a ZL 1 clone with a real ZL1 motor
I'm sure that Technology has Improved......but back in the Sixties......I know that the Police had a method of lightly heating the Stamp Pad with a torch, then they would apply some sort of Acid to the Pad and it would bring up any Stampings that were pre-existing....
I know of a couple guys that were "Busted" by this procedure ........  Ken
