TSP VVT-1.2 L99 Camshaft
Regular price $389.99 Save $-389.99Check out our new TSP L99 Stage 1 VVT camshaft! Since we are one of the only companies that designs, grinds, and tests our camshafts in-house, we are able to constantly test for better lobes, grinds, and combinations! Our camshafts are the result of endless engine dyno testing on our SuperFlow 902 engine dyno using a factory GM L99 engine with factory cylinder heads. 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.
Cam Specs: 223/233, .629"/.629", 114 LSA

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!

The all-new PRC aftermarket casting LS3 cylinder heads are designed to flow considerably more than a gm ported casting while keeping the port sizes smaller for improved port velocity. The result is a cylinder head that is smaller than a stock GM LS3 port and moves more air than any other ls3 cylinder heads!
The all new PRC aftermarket casting LS3 heads are the perfect option for customers looking for the ultimate in LS3/L99/L92 cylinder head technology
The PRC aftermarket casting LS3 cylinder heads are available in 2 different configurations:
- 255cc Runners for max effort stock cube LS2/LS3/L99/L92 engines looking for a 370cfm cylinder head that can be aggressively milled & still keep better than stock p/v
- 260cc Runners For LS3/L99/L92 stroker engines needing a 380cfm+ cylinder head!
The 13-degree valve angle will allow for the ability to run more compression and larger camshafts thanks to additional piston-to-valve clearance!!

TSP Stage 3.2 LS7 N/A Camshaft
Regular price $389.99 Save $-389.99This camshaft features custom-ground lobes specifically designed for the LS7! These lobes not only make excellent power throughout the entire RPM band, but they are also much more stable. So, this equates to a quieter and longer lasting valvetrain compared to most other comparable camshafts on the market. Like all TSP camshafts, they are 100% developed, ground, and polished in-house using our state-of-the-art Landis CNC camshaft grinders!
2800 - 6900 RPM Power Band; This is an excellent performance camshaft with an aggressive idle! Custom tuning will be required for this camshaft. It will have a lopey idle and will pull hard through the mid and upper RPM band.

Our camshafts are the result of endless engine dyno testing on our SuperFlow 902 engine dyno using a factory GM L99 engine with factory cylinder heads. Our L99 Stage 3 camshaft will be a great choice for those looking for a more aggressive camshaft that makes excellent power but not wanting the most aggressive setup possible. This camshaft will have a noticeable lope at idle and will drive well with a minimum stall speed torque converter of 3,200 RPM. This cam makes more power than the factory camshaft from 3,000 RPM all the way to the 6,600 RPM peak.

Texas Speed and Performance LS3 Cam Package
Regular price $786.99 Save $-786.99Your Choice of Camshaft, Double Spring Kit, and Hardened Chromoly Pushrods.
This package will include the following items:
- Your LS-3 camshaft of choice
- TSP Dual Spring Kit w/ PAC Polished .660" Springs, Retainers, New Seats, & New Seals
- 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. 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.
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.
