1984 GMC C3500 Performance Engines

Mr. Gasket Performance Intake Gaskets are manufactured from cellulose/nitrile composition gasket material. This is a low density material that conforms well to irregular surfaces and has very good crush resistance at high flange pressures. They provide excellent sealing and durability as the material is designed for sealing gasoline, oils, water and coolant in applications up to 350 degrees Fahrenheit. While die-cut for an excellent fit, they can be trimmed if necessary for modified port applications. Comes complete with front & rear manifold end seals. For original equipment replacement, high performance street, drag race and oval track.

HoleShot 3600 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) APPLICATION: HoleShot 3600 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. If your vehicle is equipped with a plate type nitrous system, you will need a Nitrous Holeshot!! Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Furnace brazed impeller. New precision steel alloy pump drive tube. New heavy duty needle bearing between stator and impeller (not a thrust washer). Needle bearing between stator and turbine. Furnace brazed turbine.

Maximum cooling for street and racing engines. Internal passages are balanced for maximum flow. Impeller is larger than others for maximum pressure. Impeller vanes dramatically increase flow rates. Equal distribution to both sides of block. Only flows in one direction for optimum efficiency. In the early days of the automotive performance industry, you either ran what was available, or you fabricated something you thought met your needs. Such needs were the building blocks of this industry, and it was through the efforts of many that we have the automotive aftermarket, but it was through the work of one name in particular to which many in the industry owe a great debt, and that name is Edelbrock.
