I appreciate the effort it took for you to admit you're wrong, but you are a bigger man for it. Just don't be so hard on yourself.
I never said 200lbs; I said between 125lbs and 200lbs depending upon how it is outfitted. I am quite comfortable with the 150lb figure cited by ERA. That's 150lbs I'm moving from the front to just in front of the rear wheels since I weigh at least 150lbs more than the average person--and all within the same plane given the size of my ass. The ultimate redistribution of weight!!!
As much as I love Audi R&D, I think Arias (now Shelby) has been around long enough to know what the hell they're doing. I think they've built aluminum motors longer than Ford built the SO. BTW--I dry-sleeved a Vega GT block back in 73 and ended up with a very nice (and light) 194hp (dyno) motor that ran perfectly for 140,000 college-days miles (including dozens of autocrosses). Once Porsche (or rather, Mercedes) figured out how to apply Teflon, even the 928 non-sleeved aluminum blocks performed faultlessly (though the rest of the cars fell apart around them).
Nothing at all wrong with a 60's SO block. It is amazing that 30+ years later, it is still a great motor that is almost as good as a modern aluminum Shelby.
Finally--having Turk in control of certain buttons for this site does give your "arguments" a little nitrus boost on the numbers.
