Help me choose a cam
Help me choose a cam Im in the process of doing a twin turbo build, but im stuck on which cam i should get. Ill be using an LS2 block stroked to 403 cu.in., heads that flow 320+cfm int. and 250+cfm exh. @ .600" lift., 8:1 CR, twin Garret GT35R compressors with a 1.06 a/r turbine, and the biggest FMIC i can get to fit. Id like a good power range up to 7500rpms and beable run anywhere from 8 to 20psi of boost. The car will be used mainly for weekend cruising, but id like to beable to crank up the boost and put down some nice times at the track.
Im not a cam expert but i know enough to get me by. So far this is the cam ive come up with-
244* int. and 238* exh. duration @ .050" lift
.655" int and .640" exh lift
115* LCA
and a 119*-125* Intake Centerline
Let me know what you think, Thanks, Allen

Sounds pretty stout, maybe you can do some searching on what hydraulic cam the OH Boyz were running the first year their Formula was out. There are only a small handful of turbo cars in this section that see over 7000 rpms, and many of those guys (Harlan; OH Boys 2nd year of racing; Stenod white Formula)) are running solid roller cams. I also wonder if all those guys would see a single plane intake as being required.
