The Texas Speed 228R Camshaft on a 110 degree lobe separation is one of the most popular grinds in the TSP lineup, aimed at 5.7L and 6.0L LS engines that will see daily driving but still want a strong, aggressive power delivery. It uses 228 degrees of duration at .050" on both the intake and exhaust with .600" lift, and Texas Speed rates the idle as very aggressive.
Texas Speed reports a gain of roughly 45 to 50 rear-wheel horsepower in dyno testing and about 5 to 7 more horsepower than the 224R. The cam fits stock, untouched cylinder heads with no piston to valve clearance problems reported, though measuring is always recommended. Upgraded valve springs are required, and because of the cam's size Texas Speed calls for a 3200 rpm or higher stall converter in automatic cars. A custom tune is required after installation.

FAQ
What engines is the Texas Speed 228R 110 LSA camshaft for?
Texas Speed lists the 228R camshaft as best suited to 5.7L and 6.0L LS engines. It is a street performance grind with 228/228 duration, .600" lift and a 110 degree lobe separation angle.
Do I need a stall converter with the 228R cam?
Yes, for automatic cars. Texas Speed says the 228R is large enough that a 3200 rpm or higher stall converter is required, and recommends at least a 3.23 rear gear in automatics for the best performance.
What valve springs does the 228R camshaft need?
Upgraded valve springs are required. Texas Speed recommends PAC 1219 springs or the TSP .660" dual valve spring kit to handle the .600" lift of this camshaft.
How much power does the 228R camshaft add?
Texas Speed reports dyno gains of a solid 45 to 50 rear-wheel horsepower with the 228R, and about 5 to 7 horsepower more than its 224R camshaft. Results depend on heads, intake, exhaust and tuning.
What is the difference between the 228R on a 110 LSA and other 228R versions?
This version uses a 110 degree lobe separation angle, which Texas Speed rates as a very aggressive chop at idle while still being a great daily driver cam once tuned. Texas Speed also offers the 228R on other lobe separation angles for a different idle and power character.
Is a tune required after installing the 228R camshaft?
Yes. A custom tune is required after any camshaft swap so the engine idles and drives correctly with the new profile, and Texas Speed notes the 228R is a great daily driver cam once properly tuned.
