( Brand: Bagger/ Sliv-o-lite ), ( Manufacturer Part Number: P-747.20 ), ( Part Type: Piston )
The P-747.20 SLIV-O-LITE piston set is a high-performance upgrade for your 1977-1993 Ford 351W engine. These pistons are specifically designed for the 1171 020 SLIV Lite Bagger application, ensuring a perfect fit and optimal performance.
The P-747.20 pistons are made from forged 2618-T6 aluminum alloy, which is known for its strength, durability, and heat resistance. This material allows the pistons to withstand the high temperatures and pressures generated by the engine, thereby increasing the engine's horsepower and torque.
The pistons feature a unique SLIV (Specially Lined Iron Vane) design, which includes a graphite-impregnated, high-silicon, chrome-plated skirt. This design reduces friction and wear, allowing the pistons to run smoother and longer. The SLIV design also helps to reduce noise and vibration, resulting in a quieter and more comfortable driving experience.
The pistons come in a set of four, each with a 0.030-inch overbore. The overbore allows the pistons to fit into the engine cylinder with a slight enlargement, which can help to increase the engine's compression ratio and power output.
The P-747.20 SLIV-O-LITE piston set is also compatible with a wide range of aftermarket ring sets, allowing you to further customize your engine's performance to your specific needs.
In summary, the P-747.20 SLIV-O-LITE piston set is a high-quality, performance-enhancing upgrade for your 1977-1993 Ford 351W engine. With its forged aluminum alloy construction, SLIV design, and overbore, this piston set will help to increase your engine's power, reduce friction and noise, and provide a longer-lasting and more reliable performance.
