The Texas Speed Low Lift Cathedral-Port Cam Kit pairs one of the Texas Speed low lift truck camshafts with a set of .550" lift single beehive valve springs for 4.8L and 5.3L Gen III and Gen IV LS engines. Because the cams are ground for .550" lift, the factory retainers, locks, seats, seals and pushrods can be reused, which keeps the swap simple and inexpensive. Choose from the Stage 1 through Stage 4 low lift cams, the Chopacabra, a 6.0L Chopacabra grind or the MaddMaxx.
Texas Speed tested these cams at the crank against a stock 5.3L camshaft and reports gains of 45.1 hp and 21.5 lb-ft for Stage 1, 51.4 hp and 22.9 lb-ft for Stage 2, 53.4 hp and 22.0 lb-ft for Stage 3, 68 hp and 23 lb-ft for Stage 4, 67 hp and 26 lb-ft for the Chopacabra and 82 hp and 18 lb-ft for the MaddMaxx. Pushrod length should always be measured, and may change if the lifter style changes during a DOD delete. Tuning is required.

FAQ
What is included in the Texas Speed Low Lift Cathedral-Port Cam Kit?
The kit includes the Texas Speed low lift camshaft selected at ordering and a set of .550" lift single beehive performance valve springs. Factory retainers, locks, seats, seals and pushrods are reused.
Which camshafts can I choose with this low lift kit?
Texas Speed offers the Stage 1 (208/214), Stage 2 (212/218), Stage 3 (216/220) and Stage 4 (222/226) low lift cams, the Chopacabra (214/222), a 6.0L Chopacabra (220/228) and the MaddMaxx (228/232), all ground for .550" lift.
How much power does a Texas Speed low lift cam add to a 5.3L?
Texas Speed reports crank gains over the stock 5.3L cam of 45.1 hp for Stage 1, 51.4 hp for Stage 2, 53.4 hp for Stage 3, 68 hp for Stage 4, 67 hp for the Chopacabra and 82 hp for the MaddMaxx. Results vary with supporting parts and tuning.
Do I need new pushrods with the Low Lift Cam Kit?
Factory pushrods can normally be reused, but Texas Speed advises measuring pushrod length before installation, especially if the lifters are changed during a DOD delete. OE pushrods are an optional add-on.
What is the difference between this kit and the Texas Speed Beehive Spring Cam Kit?
This kit uses .550" lift low lift cams with .550" single beehive springs so factory pushrods and retainers can stay. The Beehive Spring Cam Kit uses .600" lift cams with PAC 1219 springs and includes new chromoly pushrods.
Is a tune required after installing a low lift cam?
Yes. Texas Speed states tuning is required for all aftermarket camshafts, and the calibration changes needed will vary with the application.
