ZL-1 block versus Can-Am block?

And therein lies the fundamental problem with old race cars.

Too many owners, too many modifications, tags gone, sketchy histories, no documentation. Several obvious recreations being paraded around as the 'real car'.

Those who have been on the sites for a long time may remember the Dick Harrell '68 Camaro FC mess.

I'd say "SOME" old race cars. There are existing originals that are fully documented and have never been torn apart, destroyed, or left to biodegrade into the earth; some are still in competition. I will agree that quite a few bogus cars are, or have been, portrayed as the real thing and those imposters may cloud the judgment concerning period race cars in general. It's sad, indeed, but the entire hobby is rife with illegitimate examples of race cars, muscle cars, classic cars, etc.
And yes, the 1968 DH FC is a prime example....and the 1970 GT probably will be in due time.
