Sounds high to me for a small block NOM. My opinion only. Have you looked for any comparables? It may be tough finding sales data on NOMs, nearly every Corvette you see for sale is "numbers matching". If you can find a similar NOM, that may give you a ballpark figure. Else you're just getting a lot of opinions based on personal values.

Actually the '72 LS-5 had further adjustments to the carburetor and distributor timing from 1971. The horsepower rating dropped further to 350 hp.

Matching numbers are out, not a factor which would boost value. The engine code could be significant to the buyer if the fact it was built with a big block is important, possibly looking into a restamped block or finding the original? Maybe installing a 'correct' block, looking into having it judged? I'd take it a step further. Does it still have the big block components? If he's planning to install another big block, that could be a consideration, would be for me, depends on what the OP is looking for. If the code doesn't indicate a big block or many of the big block parts are missing, it would seem to be just another small block NOM.

I would further add that a nom, W code BB car w/a BB motor could be worth more than a nom, K code SB car w/a SB motor,...other factors being similar. FWIW.
