At Thunder Racing, we are proud to carry a broad selection of camshafts from the top manufacturers in grinds ranging from very streetable to all-out race. From mild to wild, we've got a camshaft in the power-range that you are looking for. If you are unsure which application would be right for you, please call our technical department at 225-754-7223 so we can discuss the different options that are available and make sure you get a camshaft grind that is best matched with your application.
For those looking for the ultimate in performance, Thunder Racing has select camshafts that utilize more aggressive lobes than standard "off-the-shelf" LS- series cams. The lobe profiles on these camshafts are engineered for maximum "area under the curve." This means that for a given duration and lift, the lobes on these cams will hold the valves open longer, translating into more power than a standard camshaft lobe in the same RPM range. Please call if you have any questions regarding these camshaft applications. Choose from any of our Thunder Racing camshafts listed below, or, if you prefer, we can spec a custom-ground camshaft to your exact needs for an additional $25.00 charge.
