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.

A NON-DOD CAMSHAFT IS REQUIRED!

Check 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!

All PRC cylinder heads are extensively researched and tested. 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!!  

With all PRC cylinder heads, quality and performance are our two highest priorities! In addition to performance, you will not find a better performing set of cylinder heads at this price (cost is for the pair!). Call one of our sales consultants today if you have any questions or if you would like to discuss your specific application.

TSP's all-new line of LS3 camshafts are the result of our latest round of engine dyno camshaft development using our state-of-the-art Superflow 902 engine dyno. Using a brand new LS3 crate engine, we started from scratch to build the most powerful LS3 camshafts available in the country.  Texas Speed & Performance continues to test and develop new designs to make sure that our customers have the BEST camshafts available!

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!
