One of the reasons

Johnny Dart, Beefing as you put it on purists is something two fold. I am a bonified designer and hotrodder and I have had and still have many modified vehicles, I am by no means a purist or someone who dedicates their life to keep something original. On the other hand there are those who are purists, some of which are hypocritical in terms where they believe everything should remain their way or at least the way which it was intended to.......... Yet down the road, they will use other manufacturers engine parts, transmissions and rear ends to accomplish what?

That is not my problem, it's their problem and reminds me of the " do what I say but not what I do " type which lives to suppress others from evolving..
