Speed Inc LS7 Street Cam 227/243
$459.99
By far, our favorite LS7 grind. We've tested this cam versus several of our competitors gimmicky named cams, and this is BY FAR the best option. Choosing an overly agressive cam is one of the most regrettable choices you can make. Don't be fooled by the term "streetable". Our street grind features an audible idle, especially when your dual-mode exhaust valve is open with almost NO DRIVABLITY COMPROMISES. We've made upward of 580RWHP with supporting bolt-ons and our CNC ported PRC heads. Expect track times in the mid to high 10's at 133-135 MPH trap speeds with that combo. Stock heads will yield roughly 25 less HP. Duration @.050 is 227/243, lift is .613/.623 with 1.7 rocker and .649/.660 with a 1.8. It is ground on a 115.5LSA. View some clips below.

Our cams are custom ground for us by Comp Cams. 3-bolt core is standard, but available in single bolt for newer GenIV engines. We also offer a 3 bolt cam conversion kit for those with an original single bolt LS3 who want to upgrade to the stronger 3 bolt design.
