The Texas Speed Low Lift Converter Killer Camshaft is a cathedral-port LS grind for truck and SUV engines that want an aggressive idle while keeping the factory torque converter. The .550" lift lets it run on GM LS6 beehive valve springs, which keeps the parts cost of a cam swap down on a 4.8L, 5.3L, 5.7L or 6.0L engine, and the 108 degree lobe separation angle produces the pronounced chop the name suggests.
Texas Speed tested this camshaft on a stock Gen IV 5.3L with factory 862 cylinder heads, LS6 valve springs and a TBSS intake manifold and recorded gains of 67 crank horsepower and 26 lb-ft of torque. Results vary with heads, intake, exhaust and tuning. Upgraded valve springs are required, no stall converter or rear gear change is needed, and a custom tune is required after installation. Texas Speed lists this camshaft as not legal for sale or use in California.

How does the Converter Killer compare to the Texas Speed Chopacabra truck cam?
Both are 214/222 duration, .550" lift, 108 LSA cathedral-port grinds that run on LS6 beehive springs and a factory converter, and Texas Speed publishes the same dyno result for each. Buyers choosing between the two should confirm with Texas Speed which name is current.
