273 power? HOW?

I thinknow days more people are looking for 273s for A-body restore projects which is making them harder to find.
Somewhere I read about a guy trying alternative pistons. Pontiac maybe ?(dunt remember)
Near the same diminsions though and affordable at about 32 bucks each.

I have two I'd love to get rid of for cheap, just so they can be used. I myself haven't seen that they are in all that much demand.

Yes, I think people love to restore the Formulas 'S' cars and keep things looking stock - but I can't think of one example of a restored 2brrl car - yeah I'm sure there is a few cases, but not many.
