The Texas Speed Madd Maxx Low Lift Camshaft is a maximum-effort grind built around a .550" lift so it can run on GM LS6 beehive valve springs, which Texas Speed calls the best power per dollar cam package on the market. It is intended for 4.8L, 5.3L, 5.7L and 6.0L LS engines with cathedral-port heads, and the 228/232 duration on a 110 degree lobe separation with a 105 degree intake centerline gives it a choppy idle with a 1,800 to 6,500 rpm operating range.
Texas Speed reports gains of 82 horsepower and 18 lb-ft of torque with this camshaft and recommends a compression ratio of 9.5:1 or higher. Automatics need a stall converter of at least 2,800 rpm, and a 3.23 or steeper rear gear is listed for optimal performance. Texas Speed describes it as a good daily driver cam once properly tuned, and a custom tune is required after installation.

FAQ
What engines does the Texas Speed Madd Maxx cam fit?
The Madd Maxx is made for 4.8L, 5.3L, 5.7L and 6.0L LS engines with cathedral-port cylinder heads, including the LS1, LS6, LS2 and the Gen III and Gen IV cathedral-port truck engines.
Can I use LS6 valve springs with the Madd Maxx camshaft?
Yes. The Madd Maxx is a low lift design at .550" that Texas Speed built to run on GM LS6 beehive valve springs, which keeps the cost of the spring upgrade down.
How much power does the Madd Maxx cam add?
Texas Speed reports gains of 82 horsepower and 18 lb-ft of torque with the Madd Maxx camshaft. Actual gains depend on displacement, heads, intake, exhaust and tuning.
Do I need a stall converter with the Madd Maxx?
Yes, in an automatic. Texas Speed requires a stall converter of 2,800 rpm or higher and lists a 3.23 or steeper rear gear for optimal performance with this camshaft.
Is the Madd Maxx a daily driver camshaft?
Texas Speed describes the Madd Maxx as a good daily driver cam once properly tuned, with a choppy idle and a 1,800 to 6,500 rpm operating range.
How does the Madd Maxx compare to the Chopacabra truck cam?
Both are .550" lift cathedral-port cams that run on LS6 springs. The Chopacabra (214/222, 108 LSA) is factory converter friendly, while the larger Madd Maxx (228/232, 110 LSA) is a max-effort grind that needs a 2,800 rpm stall converter.
