LM,
That's a cool page of info...do you have a link for that comparo site?

Vig, I understand your enthusiasm to debate...I didn't bring up squat
other than my ol'pushrod V8 is, as J pointed out, highly detuned/under
stressed, provides gobs of torque at any rpm, still manages to get to
6G RPM+, is a great motor and delivers 30+ real world mpg. I was not
pumping Vettes, but I was boasting about what I perceived to be a
great value, very dependable, haul azz fun and "touring" 2 place car,
slightly in defense of those that remark about its unrefined state or,
it's just a Chebby with a big V8, etc. ...

When I'm driving it, I don't notice lack of "Nappa leather", doodads or
refined accoutrements, .

I realize the lil' 3.0 IL 6 in our X, is probably well advanced over the
small block V8 in our Vette, but I sort of don't care or think about it,
much. They both do "well", for how they are designed, or in the case
of the Vette V8, a lack of or, older "design".
My Qtr's up...
