Two examples of "Stealth" fighters....

Here's a couple perfect examples of the stock looking sleepers I spoke of in the last post. # 1. 1969 Chevelle Malibu. This car had a later-model 350, a TH350 trans and a 2.73 rear end when the owner got it. He wanted a stock-looking sleeper. The engine was in good shape, so he left the short-block alone. He added some 305 heads-the 58cc combustion chambers raised the compression to about 9.6:1.  He added a Comp Cams 270H Magnum cam ( 224 degrees duration@.050, .470 lift.) He used the GM Performance Parts Iron Z/28 manifold and a custom-jetted quadrajet. The exhaust was 2 1/4 inches with "Turbo" style mufflers. He used a B&M 2,000 rpm converter and a 3.73 axle ratio. He powerbrakes it to 2,000 and it shifts automatically at 5,400 rpm. It runs high 13s and looks like a "little old lady" Chevelle. # 2. 1978 Pontiac Trans-Am. This one was a 400, 4-speed, 3.42 geared WS6 car.  The owner milled the heads .060 to raise the compression to 9.0:1. He used a Melling cam with 212 /224 duration@.050, and .442 / 465 lift. This cam has the same duration, but more lift than the factory "068" cam. The 75-79 Pontiac intakes have a restrictive throttle opening which limits power above 4,000 rpm. He replaced that with one off a '71 Gran Prix. He used 21/4 inch pipe and Turbo mufflers . He drops the clutch at 3,500 rpm and shifts at 5,500. It runs low 13s on street tires, spinning all of low gear.  Both of these cars are great drivers, look stock, and are fast enough to beat 95% of the stoplight challengers they might meet.  These types of machines are easy to build.
