Default Education Needed 73 Big Block

I was hoping some of you could give me some advice. Normally, I reside across the hall but I was requested to come up with a value for my cousins coupe he wishes to sell this spring.


I need to educate myself. On my 86, there is a list of options codes under the armrest. Does that 73 have a similiar label stuck somewhere?



Any suggestions on what to look for as far as options, color combinations, axle ratios, etc that would effect the value?



Thanks in advance...

there is no sticker on a 73 to tell you the options. on the drivers door jam there is a small metal tag that has the build date, exteior, and interior colors. and the 5th digit in the vin tells you the engine.

If you get lucky you may find a build sheet glued to the top of the gas tank.

No. No such in-car information on any Corvettes prior to the C4s.

Documentation from prior owners of the car. Window sticker, Corvette order copy, dealer invoice, etc. You can check for a build sheet on the gas tank, but it's probable the sticker disappeared years ago. There is also the possibility any remaining evidence of the tank sticker could be illegible.

First and easiest thing to do is jot down the numbers off the pad on the block at the front of the right head. This will give you the engine assembly date and code and a VIN derivative of the car the engine was originally installed in. If the engine is original, the codes will be correct and the VIN will match the consecutive unit number of the Corvette.
