Edelbrock 60779 Performer RPM Cylinder Head.
The Edelbrock Performer RPM Aluminum Cylinder Heads feature threaded inserts in the rocker studs and exhaust manifold bolt holes for superior strength and durability. These cylinder heads offer dyno-proven increases in horsepower, throttle response, and torque throughout the RPM range. These heads have outstanding features that include phosphor-bronze valve guides, interlocking ductile iron valve seats and premium one-piece, stainless steel, high-flow 2.02″ and 1.60″ intake and exhaust valves. This head features a 63cc combustion chamber along with a 171cc intake port. Heat treated, machined steel retainers and valve locks along with heavy duty valve springs are good for 0 .575″-lift cams. This powerful head uses the stock location for intake and exhaust bolt holes and flanges spark plugs and valve cover rails for compatibility with aftermarket parts.

The Edelbrock Performer RPM hydraulic roller camshafts feature more aggressive profiles without excessive valve overlap. The roller lifters reduce friction significantly and eliminate break-in problems. They also permit higher valve velocity, increasing performance while maintaining good manifold vacuum and drivability. These cams are for high performance street use only and are not for heavy vehicles. They should be used with Edelbrock or other aftermarket cylinder heads, adjustable valve train components and at last 9.5:1 compression ratio. Headers, high energy ignition systems, lower than stock rear end gearing and a high performance torque converter in automatic transmission equipped vehicles are necessary to gain all of the performance in these camshaft kits. In some designs the camshaft also drives the distributor and the oil and fuel pumps.

The camshaft controls the intake and exhaust valves of internal combustion engines in cars. It is driven by the engine’s crankshaft via the timing belt or timing chain.

Construction of the engine determines the number of camshafts. The camshaft has its name from the hardened and ground cams that are mounted on the shaft. The shaft rotates on its axis – the cams open the valves and push it or close it. Depending on the type of engine it is a common camshaft for the valves, or there are two camshafts are used: one for intake and one for the exhaust valves. For four-stroke engines, the camshaft rotates at half the speed of the crankshaft.

Quality remanufactured fuel injectors that are electronically tested for correct electrical resistance and for coil weakness. Good units are then disassembled (micro filter, seals, pintle caps and plastic spacer are removed.) Injectors are simultaneously cleaned in ultrasonic tanks specially designed to clean fuel injectors. All units are individually back flushed to remove the broken dirt particles, these particles can not be removed thru the injection orifices therefore are driven out thru the inlet of the injector. All injectors are then mounted on the flow bench in an inverted position to allow them to reverse flow at a considerable pressure. We run a high performance injector cleaning solvent thru the injectors for 30 minutes, completing the cleaning process. This process assures all dirt particles are completely removed from the injector. Injectors are now mounted on the flow bench in the correct position to begin the testing procedures. We apply 60 PIS of pressure (more than a regular multi-port fuel injection system) and maintain the injectors with no signal to them for 30 seconds to make sure there are no leaks. Depending on the original manufacturer presentation, the injectors are either painted or polished to give the best cosmetic appearance possible. Injectors are then assembled with new replaceable components (filter baskets, pintle caps, O-rings and seals) and a final test is performed with all new components on injectors. The purpose of this test is to make sure the filter basket; o-rings, seals and pintle caps are positioned correctly and are not disturbing the flow or the spray pattern of the injector. Injectors are lubricated with special oil and protective caps are placed on both ends to extend the shelf life and assure that when they are installed in the vehicle they will be in optimum operating condition. Each injector is individually bagged.
