MKIII SPO 2407 / Guardsman Blue/White









This project has been very special to us at Gear 6 Performance. The Superformance MKIII SPO 2407 was our first Demo car and the first car we sold to a special customer, Gordon from California.

After 4 ½ years of ownership and 7,000 miles, Gordon decided it was time for some upgrades and more power. The car was fitted with the “Big Brake” upgrade, racing shocks and springs, Kevlar clutch, MDL release system, Quick Time Bell Housing, and the engine was rebuilt making an incredible 620 HP on pump gas.

Engine modifications included Callies Forged Crank and Rods, Coated Diamond Pistons, custom ground Comp solid lifter cam, Jessel shaft rocker system, Bill Wilson head work, and a custom built Gary Williams carburetor. To say the car is now a rocket ship is an understatement. 620 HP in a car that weighs 2480 lbs. gives a pounds to horsepower ratio of 4.0!! What a ride.. and it sounds even cooler, if that's possible.


SOLD: Superformance MKIII SPO 3047 Makes A Very Special B-Day Gift

Custom 1969 Camaro Pro Street
The best word to describe this Custom 1969 Camaro Pro Street is RUDE..

496 Cubic Inches of angry Chevrolet Big Block, making 888 Horsepower with a Pro Charger Supercharger. Loud at both ends (exhaust & supercharger) This car was in the shop for some upgrades, repairs & suspension tuning. The car is a blast to drive with all that power and also has power steering & air conditioning. Makes you wonder what Cesar will buy next.
