Market Value and "Numbers Matching" versus "Original Motor"

[Lynn]

For most collectors, a #1 car with a restamp will get discounted significantly to a #1 car with the "born with" engine.

I know it would to me.

I agree with that Lynn. Most popular price guide definitions of "#1" or "#2" do not include factors like drivetrain originality. Additionally, most prices achieved in public and recorded as "#1" are very often NOM or restamps, but simply reported by the auction house as "#1" condition. Those I know with fully documented, concours cars with factory original drivetrains and stamps are seeking a premium OVER #1 Price Guide Figures.

My question is, what is the baseline price for the discount?

There really is no baseline as it depends on the car that is missing the motor. You just can't put a percentage on it. On a '67 327/350 horse Corvette convertible, it could mean as much as $10,000 to $15,000. On the same car with a 427/435 it could be $50,000 to $75,000.
