Are Lighter 440 Pistons Worth the $$$ for the Street?

A lighter rotating assembly will rev slightly quicker and could feel snappier, specially on the street.
Is it worth spending $2-300 'once', and having a more fun engine 'everytime' you accelerate your car?

Folks use lightweight wheels on car too. Some for the looks but often because they make a car more fun to drive.

That's a solid answer.., I can't disagree. At that point: add a set of H/I beams & stroke it. We still don't know budget & PATIENCE to build. :???:
