Texas Speed TSP Chopacabra Cam Kit with Springs Seals Pushrods LS Truck Camshaft 4.8 5.3

Overview

A truck with a stock converter and cathedral port heads is the setup this TSP cam is built for. The kit supplies the camshaft with springs, seals and pushrods for a self-contained valvetrain refresh.

Texas Speed publishes the grind details, so a builder can check the numbers against their heads and compression. The cam is described as loud and aggressive and needs the recommended LS6 springs, and the power gain claim comes from the seller, not from independent testing.

Who it's for

Builders of LS truck engines with cathedral port heads and enough compression who want an aggressive cam without swapping the converter or rear gear. Low compression or different heads change the result.

Pros and cons

Performance notes

Duration and lobe separation decide where the engine makes power and how rough it idles, and the stated compression ratio matters because a bigger cam bleeds off cylinder pressure at low speed. The listing reports a power and torque gain at the crank under the seller's testing, so treat it as a claim, not a guarantee.
