CHEV VEGA blocks have been melted down for years to make pistons for the Big Block Speed Jobs ,when they were on 80% nitro and full pipes they were going through a piston every couple of flights
LOL, I have one of those rods melted down by Frank Garzon. Story was he melted part of a Chevy Vega block and poured it into a pipe. The thing looks crude. I never used it because uncle Henry gave me a piece of hi Si rod that he uses. Still have some of that too.
