Sam,
The author of that article clearly doesn't get it.
Ram Air III & IV carbs are the same I believe and also
quite expensive to be sure. How rare is rare you say?
Case in point, right now I am looking for a correctly
dated Holley for my buddies 1970 L/78 Nova. Well, guess
what other car uses that carb.? 1970 LS-6 ! So the price
to be paid for this carb will always be dictated by the
LS-6 community......
I'd suggest writing a letter, or response to this article
and see if Hemmings prints it.
