1975 Plymouth Duster 528 Hemi - Extreme Pressure

Even though Dave does drive this car on a regular basis, the interior is still fairly spartan. The owner-designed-and-built interior consists of a pair of black fiberglass seats and a custom-built, polished stainless steel dash filed with Auto meter gauges. No radio and with one look over the modified U.S. Body Source hood, you realize why.

The engine began life as a Mopar Performance Mega block with 4.500-inch cylinder bores. An Eagle 4.150-inch crankshaft slings the Manley rods and Ross pistons up and down underneath the MP aluminum heads. Making the valves move a whole lot of air and fuel is a Straightline Performance roller camshaft with a .625/.604-inch lift, and .248/.256-degrees of duration at .050-inch lift. The biggest addition is the BDS 8-71 blower. On the street, Dave needs to be careful because the blower is quite capable of creating enough vacuum to suck a robin to its demise. Topping it off are a pair of 1050 Holley Dominators. From there, the Lipshifted Perfomance 727 features goodies such as a Dynamic 911/42-inch converter and Turbo Action rebuild kit. Finally, Applied Racing Technology of Clearwater, Florida, built the Dana 60 filled with Richmond 4.56 gears and Strange axles.

Although Dave tells us this is his first-ever attempt at building a car, we have to give him credit for building something that looks this good and drives this well (we've witnessed it). When the pressures of life seem too much to take, Dave's Extreme Pressure relieves him.
