Tri-Power EFI Dyno Output Calibration

Testing on water brake engine dynamometers validates 430 brake horsepower at 5900 RPM and 424 lb-ft torque at 4600 RPM across a wide 2500 to 6500 RPM band. Cam duration measures 204 degrees intake and 211 degrees exhaust at 0.050 inch lift, producing 0.551 inch intake and 0.522 inch exhaust lift. The engine draws 15 in-Hg vacuum at 750 RPM on 93 octane fuel, holding 45 to 65 PSI hot oil pressure.

Classic Tri-Power Subframe Fitment Standards

Standard GM LS architecture drops between subframe rails on vintage Pontiac GTO, Chevrolet Chevelle, and Corvette chassis when paired with swap engine mount plates. The crankshaft accepts 4L60E, 4L80E, or manual transmission bellhousings using standard LS flexplates or flywheels. Low profile Tri-Power components clear factory hood lines, while the retrofit oil pan clears intermediate steering linkages.

Modern Retrofit Startup Service Protocols

Pre lube internal galleries with high zinc break in oil using an oil priming tank before starting the engine. This modern LS crate engine is not engineered for marine seawater cooling, forced induction boost exceeding six PSI on stock ring gaps, or unmetered nitrous systems.

• Drain initial break in oil and replace the spin on filter after the first 500 road miles.
• Perform regular oil changes every 3000 miles or six months with high zinc synthetic oil.
• Examine high pressure EFI fuel lines, electrical connections, and oxygen sensor fittings every 6000 street miles.
