Doug:
you raise some interesting points, and i would like to expand a bit upon them.
aside from engine importers and suppliers, there are those on this board that will take numerous stands on various subjects, all the while standing on credentials that no one can varify.
the moral
don't believe everything you read, even if it makes sense!
be critical and ask questions, ask for proof, ask for and explanation or clarification
do your own research and come to an informed decision.
don't believe anyone just because it "feels" right, or agree's with what you want it to be.
question everything and everyone
especially me
