Speed Inc SI5 Cam 231/237

$459.99

Our favorite street/strip grind. Typical LS1's will make 400 RWHP with supporting bolt-ons, and more with good heads. Good for LS2 and LS3, but we prefer our SI5V2 with the additional displacement. We've sold and installated several hundred of this grind, and it never disappoints. A solid, audible lope at idle, but without compromising drivability. We recommend a 3500+ stall in automatic powered vehicles. Duration @.050 is 231/237, LIft is .589/.595 and available on a 112 LSA. Either PAC1219 or PAC1519 Single springs will work with this cam. We offer several dual spring kits as well (available separately).

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.
