Checkout our website, we have dyno data for all of our camshafts. Including LS3 & L99 camshafts. We sell more LS cams that anyone in the world mostly because of our dedication to testing & development. Nobody put the hours in on the dyno even close to what we do testing a product before it becomes available.
The best part is we can supply you with a spring kit that has been spintron tested with the camshaft lobes & was designed with our camshaft profiles in mind. The result is your getting a proven combo of parts tested together rather than a little bit of this & a little bit of that thrown together.
Give us a call so we can discuss combos with you. With a mail order tune I bet we can put together a combo you'll really like for a very very reasonable price.
