But its NOT "okay" in all aspects of the hobby... Even in the Corvette areana...
Sure, SOME people and SOME organizations have accepted restamping as acceptible, mostly because they were having a difficult time controlling it otherwise, etc...
I think it might also have to do with the people in charge of making decisions in these organizations... Perhaps someone high up in NCRS (etc) had a car without an original motor. But using their influence, then might change the policies that might benefit them...
Pardon the analogy, but why is it okay to add lead to childrens toys, to pollute the environment at will, destroy histoical artifacts, etc??? But in the US, it's against the law and we usually don't do this, etc... Point being, just because someone will thinks its "okay" doesn't mean its the right thing to do or that others will think its right...
Slightly off-topic (but close IMO), is the "survivor" or 'benchmark" car (we have these in the Chevelle hobby). Why is it that there is a certain percentage of "new paint" allowed, and how was that percentage determined? I'd say, more than a few cars have probably "conveniently" fallen within those guidelines... Of the guy that added an OEM, but used, exhaust system to his car (knowingly), yet experts still consider it "benchmark," etc... This isn't really a knock against those people that do a great job of judging the cars (Jeff, etc), but its just questionable onhow they arrive at "whats acceptible and whats not"... In actuallity, these people are experts in judging the condition and originality, but where did they get to decide what parts and percentages are acceptible (what governing body gave them the authority)? Unless they have trademarked the words like NCRS did with "survivor" etc...
