Gear Vendors Overdrive Tames This Insane 1,200HP Pro Street Dart

How many times have you been burning down the highway at 65 with the drone of 3,300 RPM echoing through the cabin and drowning out your Zeppelin? It’s usually at about that time you wish you’d have ditched the 4.10 gear-set for a set of cruiser 3.23’s. Gear Vendors can give you the best of both worlds. With their unit, that 4.10 ratio behaves like a comfortable 3.20 in overdrive.

Chuck’s Speed & RV Center recently added a Gear Vendors unit to a wicked pro street ’70 Dart. A 496 cubic inch big block is stuffed between the front fenders, followed by a 727 automatic transmission with a Gear Vendors overdrive. The big power and massive meats are no problem at all as the Gear Vendors unit can handle up to 1,200 horsepower. More importantly, the overdrive will keep this street brawler off the trailer and on the highway where it belongs.

The Snakeskin Green Dart being built is truly a one-of-none custom machine. Riding on a back-halved 4-link rear suspension and a modern coil-over conversion kit up front, the entire geometry of the driveline had to be custom engineered. Add to that the slammed ride height, and everything had to be relocated, tucked up or custom fabricated. We’ve included a few other shots from the build to show that this is no poseur machine. Visit or give them a call at (800) 999-9555 to get the perfect product for you.

That restoration experience lead to pursuing a degree in Mechanical Engineering and a career in manufacturing. Since then, the garage has expanded to include a '67 Satellite, a '72 Scamp, and a 2010 Mopar '10 Challenger.
