It uses a wide 115 degree lobe separation angle and minimal overlap, which suits positive-displacement blower and centrifugal supercharger setups where excessive overlap would bleed off boost. The result is more torque and sharper throttle response with an idle and low-speed behavior close to stock, which is why Texas Speed rates it as daily-driver friendly with a mild chop.\u003c\/p\u003e\u003cp\u003eThe cam is intended to work with a factory stall converter, so it fits budget boosted truck and car builds that keep most of the factory drivetrain. Texas Speed requires a PRC or TSP dual valve spring kit to handle the .600\" lift and 5\/16\" pushrods. A custom tune is required after installing any aftermarket camshaft.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDuration at .050\": 216\/228\u003c\/li\u003e\n\u003cli\u003eValve lift: .600\"\/.600\"\u003c\/li\u003e\n\u003cli\u003eLobe separation angle: 115 degrees, installed 4 degrees advanced (115+4)\u003c\/li\u003e\n\u003cli\u003eEngines: Stock 4.8L and 5.3L LS with cathedral-port cylinder heads\u003c\/li\u003e\n\u003cli\u003eIntended use: Supercharged or blower applications, minimal overlap design\u003c\/li\u003e\n\u003cli\u003eTorque converter: Compatible with the stock stall converter\u003c\/li\u003e\n\u003cli\u003eValve springs: PRC or TSP dual valve spring kit required\u003c\/li\u003e\n\u003cli\u003ePushrods: 5\/16\" pushrods required\u003c\/li\u003e\n\u003cli\u003eVehicle usage: Daily driver, friendly\u003c\/li\u003e\n\u003cli\u003eChop level: Mild chop\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVehicle Applications\u003c\/h3\u003e\u003cp\u003eEngine families covered: 4.8L and 5.3L cathedral-port LS.
