Factory old iron just can't compete ... ??

Think about it...
50 plus years ago the V8s were just coming of age.

Now they are seasoned.

50 more years of trial and error, material compositions, machining technics, computer modeling. Have built some of the lightest and strongest engines, not to mention the electronics.

Imagine the fuel economy that could be had if fuel had 100+ octane and engines had 10 + compression.
