I have to be honest:
The smart ass comment above was to make a comical point. Without the emoticons, it looks like I'm piling on. The point is true if drag racing. In the twisty turns, the hole 125 lb matters and you cannot apply much power in a corner. However accelerating away we're back to the 5 less pounds to accelerate thing.

Pond prices his alloy and cast iron blocks exactly the same. From memory, BBM charges $1,000 more for an alloy block. At the time, my Shelby block was $1,000 extra. But Shelby has probably priced themselves out of my engine build, if I were in the market today.
And as I said earlier, I can compensate for the alleged loss of 15-30 HP in the engine build or even a chassis dyno tune. It's awfully difficult to lose 125 lbs from my Kirkham. And it's not an either/or proposition for me. I want both, the reduced weight and the extra HP from the build and the chassis dyno tune.
