Stupid... after what, 6 years? No one can make an engine outrun the worn out chief engine?! I call BS for the show. Take the rear out of one, stick in another (it fits?) set up the four link, and the wheely bars fit, adjust them, in what little time they have and he runs faster then he ever has. Then the competition takes out power! Get real, made for TV and yawl suck it up. Like Rocky IX
