At one time I really believed in the supply and demand side of these specific Z28 parts and prices, but IMHO it's much more then that now. Is there a cut off point when the price is way out of line or does the price just keep going up? and WHO are the ones going to able to afford these parts? Definitely takes the fun out of it for me. I have a DZ block I want to sell outright or make an even trade for a numbers alternator but seem to fall short either way, but yet there are sellers on ebay asking some big money for these 2 specific parts but never sell them. So why are they holding onto these parts? IDK, just saying.
