1961 Cutlass Pushes Over 700-HP: This Oldsmobile Cutlass is truly a one-of-a-kind build. What started as a rusted and sun-beaten desert rat from Arizona has now been transformed into a classy custom build. Greening Auto Company got their hands on it and now there’s nothing on the car that hasn’t been touched. Inside and out, this should be a leading. While the factory-installed engine would have put out something in the neighbourhood of 180 HP, a new engine takes this Cutlass to over 700-horsepower. Of course, with that kind of power comes plenty of supporting mods. Included in the build was an independent rear suspension backed by a Currie TrueTrac differential. With modernized steering and handling upgrades, a Cutlass has never driven so smooth.
