PRW low-profile Engine Test Stands (ETS) with short block adapter allows the mechanic to "build" the short block, and then rotate the engine to the upright position, just like a typical engine stand. Then, temporarily support the short block and install the center supports, remove the rotating head unit, and re-attach the rear engine supports to finish the engine assembly. After final assembly, install the fuel cell, plumb for fuel, wire the electrical, connect the battery, and you are ready to run! Obviously, this over-simplifies the necessary preparation and hard work; but a great deal of satisfaction can be gained with the knowledge that your engine is ready and worthy to be installed in your hot rod, race car, street machine, truck, boat, or off-road vehicle. The patented collapsible design of the ETS is manufactured with standard parts and readily available replacement parts from the manufacturer. They offer space-saving benefits when collapsed, making them ideal for the small shop or race trailer. PRW low-profile ETS are designed to accommodate most engines and built to meet the demands of high-output racing engines and heavier big blocks, taking mobile engine test stands to a whole new level of functionality.

PRW pushrods are ideal for serious street performance and race applications. As an essential component in an engine's valvetrain system, the primary function of a pushrod is to transmit the vertical motion of the camshaft to the rocker arms. As the lobes of the rotating camshaft lift the pushrods, they push against the rocker arms, causing them to pivot and open the valves. The length of a pushrod is critical to ensure proper valvetrain geometry, therefore, it should be carefully selected to maintain the correct relationship between the camshaft, pushrod, rocker arms, and valves. Choose the PRW pushrods designed for your application needs. Key features: * One-piece construction from .080 in. wall, seamless chromoly * Heat-treated for extended durability and guide plate compatibility * Precision formed and reinforced ends * Black-oxide finished with laser etched length
