Texas Speed and Performance Cathedral "Dual Spring" Cam Package
Regular price $719.99 Save $-719.99Your 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!

Our L99 Stage 1 camshaft will be a great choice for those looking to use their factory torque converter and want the best streetability possible. This camshaft will have a slight lope at idle and will be mild mannered on the street, yet still adds incredible power.

The L99 engine utilizes Variable Valve Timing (VVT) controlled via a cam phaser. Cam phasers are computer-controlled cam gears that automatically optimize camshaft timing based on the current engine RPM. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance cams due to the wide range of valve timing movement and constantly changing piston-to-valve clearance. With the help of Texas Speed's Superflow 902 engine dyno, we were able to custom design camshafts & phaser tuning tables to allow our L99 customers the ability to bolt on the ultimate in L99 performance! Thanks to the Superflow 902 dyno, Texas Speed is the only company that currently offers a VVT camshaft with a phaser table included to properly tune the camshaft once it's installed in your Camaro!
The VVT-1, VVT-2, VVT-3, and VVT-4 camshafts are all designed with more aggressive lobes that require the removal of the AFM lifters from your L99 vehicle. This will require the installer to remove the cylinder heads & install standard, non-DOD style lifters in place of the AFM lifters. If you do not want to remove your cylinder heads you might consider looking at the AFM-1, AFM-2, & AFM-3 camshafts. All three AFM series camshafts still feature full VVT control, but they also use weaker lobes that are designed to be compatible with AFM lifters!
Each L99 camshaft Texas Speed offers will require the use of a Comp Cams Phaser limiter kit. The phaser limiter restricts the range of cam timing movement from 50° to 20°. This modification provides the necessary valve clearance for serious performance camshafts with tighter lobe separations – while still utilizing the benefits of the VVT technology.
The VVT technology is an awesome step forward in technology that allows us to create camshafts that make huge high RPM horsepower while still making great power down low in the RPM band! The result is camshafts that can make over 100 flywheel horsepower gains while still making great low RPM power!

Upgrading to the hollow-stem intake valve will shed significant intake valve weight and allow for additional lift. The titanium intake valves will be the lightest choice of the three choices and offer the best lift possible!

The Stage 4 235/248 camshaft is the perfect choice for customers wanting the MOST powerful camshaft available that still offers adequate piston-to-valve clearance on a stock short-block. This TSP camshaft is designed for all-out power and shows gains over the stock camshaft beginning at 3,100 RPM. The cam will pull really hard from 4,500 RPM up to the 6,600 RPM HP peak. This TSP camshaft makes 93 flywheel HP more than the factory LS3 camshaft! We recommend a minimum stall speed of 3,600 RPM for this camshaft in auto-equipped vehicles for streetability, but it would benefit at the track from a 4,000+ RPM stall speed. This cam is designed for LS2/L76/LS3 engines using L92/LS3 rectangle port cylinder heads!

**The factory LS3 camshaft uses a single-bolt cam design, which means one bolt holds the upper timing sprocket on the camshaft. For LS3 vehicles, you can either go back in with a single-bolt camshaft or convert to the three-bolt camshaft design that the 1997-2006 LS-based vehicles use. The three-bolt conversion kit will supply the correct 4x upper timing gear to supply the correct camshaft position signal, as well as the ARP camshaft bolt kit that will supply the three required bolts. We also offer the conversion kit with a complete, upgraded timing set for those wanting to replace the entire set.**

The Stage 3 231/246 camshaft is a great choice for customers wanting a more aggressive camshaft with excellent power gains. This camshaft is an excellent choice for customers wanting more power than our 229/244 and wanting a bit more of top-end power. We recommend a minimum stall speed of 3,200 RPM for this camshaft in auto-equipped vehicles. We recommend this camshaft for LS3 or LS2 engines using L92/LS3 rectangle port cylinder heads!

- Texas Speed Hardened Chromoly Pushrods
Note: The factory LS3 camshaft uses a single-bolt cam design, which means one bolt holds the upper timing sprocket on the camshaft. For LS3 vehicles, you can either go back in with a single-bolt camshaft or convert to the three-bolt camshaft design that the 1997-2006 LS-based vehicles use.

We also offer the conversion kit with a complete, upgraded timing set for those wanting to replace the entire set.
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.
Note: All camshafts listed will require the removal AFM/DOD, if equipped. You can purchase our DOD Delete Kit separately.
