In this video, we're taking an indepth look at the 4 Piston Racing K400 Endurance Engine, engineered for peak power and unmatched durability. This engine is built with a "nocompromises" philosophy, using toptier components to ensure maximum performance.

Starting with a robust 4P ductile iron sleeve and our resilient Ibeam billet steel connecting rod, this engine is designed for endurance. The long ratio rod is paired with a strutted ultralightweight, shortskirt piston featuring a tool steel wrist pin. This unique piston and ring package ensures superior ring seal and longevity, even under harsh conditions.

Air and fuel flow seamlessly through our renowned 400 CFM "Pro 163" CNC Cylinder Head and 4P RR4 billet camshaft, leveraging the latest advancements in 4 valve cylinder head technology. Valve motion is precisely managed by the highest quality PAC valve spring. The 4P CNC Ported oil pump and baffled pan ensure optimal oil pressure and lubrication, even under extreme gforces.

Investing in a 4P Endurance Engine means you're not only getting a topperforming engine but also a dependable support system and engine program that will last multiple race seasons. For worldwide shipping quotes, email [email protected].
