TURBO CAM for L92 6.0....hows this? Ok guys...ditched the LQ4 and came up with a LY6 (2007 6.0 with L92 heads, out of a 2007 NBS 2500 silverado). Ditching the VVT, and converting to a LS2 front cover and pickup / cam gear. Looking to make 600-650 at the wheels on pump easily with this combo, either a T76 or Borg S475 turbo, intercooled and Meth injected. The cam I have is a 218/224 .561 .561 on a 114 LSA. Im looking for good street manners and the power mentioned above. How do you think this cam will work? I also have a 224/224 .581 .581 on a 114 LSA, but I figured it is probably best to have some split favoring the exhaust to help the stock L92 exhaust port out, as it lags behind the intake flow pretty badly in stock form, which is how ill be running these heads. Anyways, how do you think the 218/224 cam will work? Is it enough LSA? Thanks as always for the input!

I know 218-224 is on the small side, but i would think it would make more power than a Z06 cam, which run pretty well. What LSA is everyone running? How much benifit would a extra 15-20 degrees of duration provide, under same boost / conditions? Im trying to keep the car very drivable and *semi* fuel efficient. I.E.....long distance drivable. I would go bigger on the cam, if the gains were a big enough.

A small cam is more then enough for 600-650rwhp. Either the TC78 or the BW475 will work. The TC78 though would be much more streetable and MUCH easier to package. Also spool up is totally different between those two units.

Chev High, Ro's Cam We made 1000+HP AND 1050 Lb-Ft Torque with that smaller (Z-06) cam in Ro's engine@Westech. (19lbs).
The reason that it worked (camshaft) was the "perfect" twin-turbo matching by Turbo-Resource.
My current work is with the L92 VVT camshaft, good for 200+HP at 20lbs boost.
To "over-cam" a turbo is CRIB DEATH.
