Here's another thing i've "heard," and i've checked wiki, but i'm still unclear: i heard that toyota copied/or was licenced to produce the chevy straight 6 and that supposedly all the parts are therefore interchangable. Could you please explain, in great detail, the complete history of this engine(s)? One of the reasons for my asking is simply my own curiosity. BUT, another reason is i work with a few teenagers at my other gig and most of them are irrefutably convinced that the Japanese produce superior quality cars---one of their favorites is the toyota supra. Even though, by their own admission, they know little about cars. (Could they be getting this mentality from their parents?) If it's true about this engine, then i want to "lay this info on them" and see how they react, because among other things, i'm pretty sure the supra had a straight 6 for most,possibly all, of it's production run.
