The Texas Speed LS3 Stroker Turbo 2000 HP Camshaft is the largest turbo stroker grind in the Texas Speed LS3 lineup, intended for 408 cubic inch and larger LS3-headed engines running very large single or twin turbochargers. Texas Speed pairs aggressive duration with a wide lobe separation angle so the engine can make big power under heavy boost while staying manageable in a large displacement combination.
Specs are 244/259 duration at .050", .644"/.633" lift, a 115 degree lobe separation angle and a 112 degree intake centerline, with a powerband aimed at high boost and upper rpm. Texas Speed sizes it for 76 to 80 mm twin turbos or a 96 to 108 mm single and says it works best with an aftermarket intake manifold. PRC VS2230 or PAC-2187 dual valve springs and 5/16" pushrods are required, with PAC-1209X springs, 3/8" pushrods and Johnson or equivalent lifters recommended above 7,000 rpm. Aftermarket pistons with valve reliefs are required.

What are the specs of the 2000 HP turbo stroker cam?
The Texas Speed LS3 Stroker Turbo 2000 HP Camshaft measures 244/259 duration at .050", .644"/.633" lift, a 115 degree lobe separation angle and a 112 degree intake centerline, with the powerband aimed at high boost and upper rpm.
What valve springs, pushrods and lifters are required?
