Chevy Big Block Engine Starting
We just finished our new Chevy Big-Block engine, wich will soon find a home
in our 1980 Camaro. It
is just one of many BBC's that I have built. It is a "street friendly" 10:1
all forged, mechanical roller with too many goodies to list . It sounds
crazy and I can't wait to feel the tire shreading performance.
