Yep, Techman. And Gene Berry (of "Bat Masterson" and "Burke's Law" fame) plays the government agent after him.

Oh...it's not a chase scene, but a good line about a car in a movie was in "The Killers," when Ronald Reagan (in the only "bad guy" role of his acting career) tells a cohort who's souping up a car: "Nail down the shocks ... you'll get another 10 mph out of it."
