| Details: |
This is the original Impala SS pre-production prototype 'mule' car, in a somewhat high performance modified form. The SS became production for 1994 and rather than dispose of the unique concept vehicle, Jon A Moss simply did his magic and take the car one step further. The ultimate street bruiser and cruiser Impala SS with Big Block power. THIS IS A MODIFIED VEHICLE. NEITHER GM NOR BARRETT-JACKSON MAKE ANY WARRANTY OR REPRESENTATION OF ANY KIND, EXPRESS OR IMPLIED, CONCERNING THE VEHICLE, INCLUDING NO WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. THE VEHICLE IS NOT CERTIFIED TO COMPLY WITH ANY FEDERAL, STATE OR LOCAL LAWS, RULES OR

Chevy had a great thing going with the 1994-95 Impala SS, the hot-rodded version of the Caprice. It was fast in a straight line and could hold its own on a road course.
Unfortunately, the Impala SS was killed with all of GM's other rear-wheel-drive cars in 1996 when the Arlington, Texas plant was converted to build more SUV's.
Little did anyone know that Jon Moss and crew at Chevy Specialty Vehicles saved the concept car that started the Impala SS program. "We wanted to keep this car vivid and alive," he says. "This car is designed to serve as one of our powerful image vehicles." So they put a 1994 Chevy Mark V 90-degree 509 cu.-in. big-block marine V8 under the hood, and called it the 510 Impala SS. Just going over the specs you can't help but say, "Wow!"
That's the creator of the Impala SS , John Moss, Manager of Special Vehicles for General Motors (Retired). The production version of the Impala SS had just 260 hp, which motivated it quite well.
But this 510 Impala SS boasts 546 hp at 5500 rpm and 610 ft.-lb. of torque at 4000 rpm, which makes it one of the most powerful sedans around. It could blow the doors off a Bentley Turbo.
Using a heavy-duty 4L80-E 4-speed automatic transmission and special stand-alone transmission control module (GM usually houses both the engine & transmission controls in a single PCM), the 510 is set up for optimum-acceleration gear shifts. The engine sends power to the transmission through a heavy-duty truck torque converter.
Underneath, the car has boxed frame rails for extra rigidity, lowered front control arms for antidive control on braking and enlarged rear wheel wells to contain the monster 17-in. tires. Plus, the whole car sits about 2 in. lower than the '94 model. Viva l' Impala SS!
