Rhoads V-Max Flat Tappet Lifters
For maximum increases in low-end torque, engine vacuum, and improved idle quality, Rhoads V-Max variable duration flat tappet lifters are the answer. These unique lifters are designed to significantly increase low-end torque and engine vacuum. This makes them the best choice for hot street, performance marine, and all racing applications. Typical vacuum increases range between 3 to 5 in. at idle when used with bigger cams. They are fully adjustable and require an adjustable valvetrain. Adjustment is similar to solid lifters--simply use a feeler gauge to adjust the exact amount of lift reduction you want, anywhere from .010 in. to .030 in., and that is exactly what you get at idle. Duration is reduced between 5 and 20 degrees at .050 in. lift, depending on the adjustment. As the rpm increases, so does your valve lift and duration. Complete lift and duration restoration take place at approximately 4,000 rpm. V-Max series lifters are also particularly suited for racing applications with vacuum rules. You can run more cam than your competition while still meeting vacuum requirements, giving you the performance advantage.

Melling Timing Chain Sets
Melling timing chain sets are designed for use with either performance or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. The crank gears are machined from stress-proof steel. Most Melling timing chain sets have three keyways to ensure accurate timing for early or late model vehicles, and to allow you to set the cam timing at 4 degrees advanced, 4 degrees retarded, or stock. However, 50-state (stock replacement) sets have single keyways. The chains are available in several styles, such as single or double roller, single non-roller, and link belt. Melling timing chain sets are not for use above 6,500 rpm. Order the model designed for your vehicle application.

PRW Sportsman Steel Roller Tip Rocker Arms
PRW Sportsman steel roller tip rocker arms are an ideal choice for a significant cross-section of engines. Anything from a mild street rebuild to the performance demands of off-track, Circle Track, and drag racing. These 4340 chromoly steel rocker bodies feature a longer pivot slot for higher lift camshafts. They're much stronger than stamped steel, so rocker arm flex is negligible. The roller tip minimizes scrubbing from the valve stem pushing forcefully against the valve guide. This reduces friction and frees up an additional 15 to 30 hp over stock models. PRW Sportsman steel roller tip rocker arms are an excellent performance alternative to stock rockers. Order the set recommended for your specific vehicle and engine size. Features, items, and specs: * Wide assortment of ratios to suit almost any cam profile * PRW RockerLocs * Rated at 350 lbs. open spring pressure * Heat-treated pivot balls
