Default What Cam? custom or shelf, let the people decide.

Ill tell ya what i have thats important and go from there

afr225's 59cc good to .650 lift but can change that if needed
2002 Ls1 bottom end, flycut
ASP 25% underdrive
ls6 intake but will change that soon (vic or fast)
255 fuel pump
36# injectors
A4 w/ 4400 converter
3.42 10-bot will also change (9" 3.90 or 12bolt 3.73)
1-3/4" headers, 3" Y with 3" e-cutout
no MAF, tuned through o2's i believe but i think those have been deleted too

Yes, i have a cam, but i think i might have messed up when buying it....soooo what cam would you stick in there with what i have. Car will be N/A and see very little street time. might throw some pills at it next year. If you can throw a sentence or 2 in there on why you suggest the cam. NOTE: T-rex will not clear, already been there, done that! open to custom grinds. Thanks!

Since your heads have such a balanced Ex. to In. flow ratio you'ld be fine
with a single pattern for NA but if you're planning the Antartica intake
enhancement I'd run 4-6 more degrees on the exhaust side. Call Geoff @ EPS
I'd be guessing based on your gear and stall like 236-242 @.050..114+5

That is funny....now we just need a cam doctor to verify if we're close
That 111 separation should only see a 100 shot as nitrous tends to favor
wider 113-117 when stepping up in the pill size. A 102 FAST manifold would
be worth some ponies as you stated.

I would call Geoff at EPS. With the small combustion chamber PTV clearance with have to be verified. EDIT notice the flycut part. Then i would ask you whats your goals of the car? I am going to run a EPS cam 234/246 on a 111 lsa I think it should run hard while still having good manners.
