Texas Speed and Performance Cathedral "Dual Spring" Cam Package
Your Choice of Camshaft, TSP Spring kit, and Hardened Chromoly Pushrods
This Package Includes the Following Items:
Your Choice of Camshaft
Includes TSP .660" Dual Spring Kit w/ PAC Racing Polished Springs, Titanium Retainers, Hardened Spring Seats, and New Valve Stem Seals
Texas Speed Hardened Chromoly Pushrods
We have two options listed for our dual valve spring kits. The default option will use our PRC integrated one-piece seat and seal that simply pushes in place. The other option is for the separate two-piece seat and seal that you typically find in any dual valve spring kit. The two-piece kit will require separate installation of the valve seals after the seats are in place, and it does require a specific tool to make sure that the valve seals are installed properly (i.e. not crooked, torn, or not installed fully). Our integrated seat and seal will make your installation much easier because it is virtually impossible to install it incorrectly! You can choose either kit for no additional charge. We have a picture listed when you select each spring kit so you can see the actual differences in the two kits.
This is the perfect upgrade package for customer looking for all the aftermarket parts needed to do a camshaft swap. Typical gains will range from 30 to 65 rear-wheel horsepower from a TSP camshaft swap alone!
We do offer the optional adjustable pushrod length checker that allows you to verify the correct pushrod length needed for your setup. We can give you a good idea of what is typically used with your engine, lifter brand, etc., but it can certainly vary from setup to setup. You can vary up to .050" in pushrod length depending on which camshaft core the cam manufacturer uses! This is NOT information that any camshaft manufacturer includes with their camshafts, so it is always best to verify the length you need to avoid any valvetrain issues.
Because we cannot stock every camshaft with every lobe separation angle, if you need parts quickly, we encourage you to call us to check availability of the camshaft you want. The LSA(s) we typically stock for each camshaft is listed next to each camshaft. Some camshafts will have to be custom ground and drop-shipped from the manufacturer directly to you!
Texas Speed and Performance "Low Lift" Cam and Springs Package
This camshaft package is specifically for the Texas Speed low lift truck camshafts that can use the GM LS6 single beehive valve springs. You will not find a better price on a cam package than this one! Very economical with respectable horsepower and torque gains, and these camshafts will not be overly radical. Tuning is Required for aftermarket camshafts.
This Package Will Include the Following Items:
Your Choice of TSP Low Lift Camshaft
GM LS6 Single Beehive Valve Springs, Set of 16, #28-12499224
You can see the power gains below (measured at crank) for each of our camshafts over a factory 5.3L camshaft that we tested on our in-house SuperFlow 902 engine dyno:
Stage 1 208/214: +45.1 HP & +21.5 TQ
Stage 2 212/218: +51.4 HP & 22.9 TQ
Stage 3 216/220: +53.4 HP & 22.0 TQ
Keep in mind that these gains are compared at the peak HP and TQ numbers. Our cams gained as much as 70+ HP and TQ at other points in the dyno graph, and NONE of these camshafts lose any HP or TQ at 2,000 RPM! You can see each of the dyno graphs for each camshaft listed on our website.
You will reuse your factory retainers, locks, seats, and seals, as well as your factory pushrods! You may need to change to a different length pushrod if you change to a different style of lifters at the same time. Some lifters do vary in overall length.
