Your out there in my book.
To think that just because it's American it's the best is rather strange.
You made a strong point to indicate that America has a strong hold on V8's and no one else can touch any of there V8's. We provide several examples and your rebuttle is to bring up the 350 engine which by and far isnt even the best example of small block american v-8's. The 350 is so popular because...well it's was popular. You could get the thing in so many different configurations in just about any mid size GM made throughout the 60's till the 80's.
With that being said one could make an obvious arguement that just about EVERY V8 chevy is behind the 8 ball so to speak. OHV motors are dated PERIOD. Until you start putting Direct injection, over head cams, and some other nifty features into the engine you arent going to convince me that's it's BEST because it's made by an American company.
I by no means think that America makes the worst stuff out there...but they arent the leader just because their company decides to headquarter somewhere.
