Its revised smooth lobe design improves street manners and increases top-end performance without sacrificing bottom-end power compared with the Katech LS7 K501 Camshaft in the intended LS7 combination.\u003c\/p\u003e \u003cp\u003eThis hydraulic roller camshaft is suitable for LS7 and appropriately configured LS3-based 416ci engine builds. Specifications include 243°\/257° duration at .050\", a 113° lobe separation angle, and +3° camshaft advance. Valve lift is .650\"\/.650\" with a 1.80:1 rocker ratio. Actual valve lift depends on the rocker ratio used in the completed engine.\u003c\/p\u003e \u003cp\u003eThe Katech LS7 K502 Camshaft provides strong mid-range and top-end performance in an appropriately matched LS7 combination. Power delivery, driveability, and operating range depend on displacement, compression ratio, cylinder heads, intake and exhaust systems, supporting valvetrain components, and calibration.\u003c\/p\u003e \u003cp\u003eIn an ideal LS7 vehicle combination using Katech CNC-ported LS7 cylinder heads, a free-flowing exhaust, an appropriate intake manifold, and supporting calibration, the Katech LS7 \/ LS3 416ci K502 Camshaft has the potential to produce 600 rear-wheel horsepower. Katech's supplied LS7 performance figures on 93 octane are 670 HP and 588 ft-lbs with an MSD Atomic intake manifold. Actual output depends on the complete engine and vehicle combination and testing conditions.\u003c\/p\u003e \u003cp\u003eThe Katech LS7 K502 Camshaft was designed to fit a stock-bottom-end LS7 with no cylinder head decking. Piston-to-valve clearance should be verified during installation in both LS7 and LS3-based 416ci builds, particularly when cylinder heads have been decked or thinner head gaskets are used.\u003c\/p\u003e \u003cp\u003eKatech's LS7 valvetrain development includes Spintron validation to 8,000 RPM with the associated test combination.
