When it comes to B-body builds, let me tell you, Steve Johnston's 1970 Plymouth Road Runner is anything but ordinary, my friends. This incredible Mopar began as a bare shell over three decades ago and has since been transformed into a track-ready beast that dominates autocross events.

Underneath, you'll find the Hotchkis TVS suspension, working its magic to keep this Road Runner glued to the pavement. Steve dropped in a low deck 400 block bored and stroked to a mind-boggling 470 cubic inches, paired with a built Tremec 5-speed tranny. With this set up, when Steve hits those corners the '70 Road Runner hugs them like nobody's business.
