@Michael Pickett- Good morning again, Mike. I forgot to ask earlier- do you remember how close in weight the piston pins were? I've always thought you could lighten them slightly by countersinking the insides of the ends 45°. Probably wouldn't lose much weight, but every little bit helps. You could also drill them out a short ways but leave the middle ¾ part.
When you're looking to take weight off of a car there aren't many things that give big reductions (like changing to an Odyssey battery or getting thinner glass made for the doors/side windows and molding the back window out of Lexan); you generally have to think ounces, or even grams. If, on average, you can remove 20-25% (sometimes you'll hit 30% or even a little more) of a piece's weight, to remove even just 25 lbs means working with 100 lbs of parts. That's a lot of holes to drill.
Oh, Lord, here I am rambling on again... Al
