Turnkey Truck Dyno Output Curves

Dynamometer testing confirms 495 brake horsepower at 5800 RPM and 490 lb-ft torque at 4200 RPM across an expansive 1500 to 6000 RPM power curve. The roller cam features 218 degrees intake and 228 degrees exhaust duration at 0.050 inch lift, producing 0.550 inch intake and 0.550 inch exhaust lift. The combustion chambers generate 15 in-Hg manifold vacuum at 750 RPM on 91 octane fuel, backed by 45 to 60 PSI hot oil pressure.

Truck Frame Spacing Bellhousing Fitment

Standard GM LS architecture drops between frame rails on Chevrolet C10 trucks and GM intermediate chassis using standard conversion plates. The crankshaft accepts 4L80E, 6L80E, or manual transmission bellhousings using standard LS flexplates or flywheels. Compact front drive brackets maintain radiator clearance, while the deep truck sump pan clears commercial steering drag links.

High Load Towing Startup Protocols

Technicians must pre prime the oil galleries using a pressurized oil tank connected to the block port before starting the engine. This modern LS crate engine is not engineered for marine bilge setups, forced induction boost exceeding six PSI on stock ring end gaps, or unmetered nitrous oxide systems.

• Drain break in lubricants and replace the spin on oil filter after the first 500 operating miles.
• Perform regular oil and filter changes every 3000 miles or six months with high zinc petroleum oil.
• Inspect serpentine drive belt alignment and high pressure EFI lines every 6000 street miles.
