Suggestions for a turbo cam? (yes i did use the search button 
)
But being new to the FI....looking for a few suggestions for a cam. Motor will be a stock 346ci w/6.0L heads (stockfor now...till i can get them ported). Right now i have stg 1.5 5.3L TEA (unmilled) heads and a FMS11 cam (228/230 112+4)
Looking to make close to (or over) 500hp with a T67-70 (rear mount) but would like something that still has some lope to it. Or is that possible?
(also about to be in the process of building a forged 370ci)
what can you guys suggest?

dont think there has been extensive work done to see what camshafts help out the rear mount the best.. it could swing either way.. i suggest staying with what you have and saving the cash for something more imperative... or even putting the stock cam back in... you can certainly get 500horse with either.
That compression is awfully high. As for cam, for a rear mount, I would run a dual pattern . Since the turbo is so far back and alot of exhaust efficiency is lost you can run a larger duration cam.

Or would i be better off going with something like a 226/226 114 or 115? (of course i would switch to the 6.0L heads too)
I would run the dual pattern setup. With the 228/230 your going to have some overlap. Even though the turbo is so far back, the backpressure is still there. The dual pattern cam would be a better match and help keep from any possible reversion at higher boost levels. Also since the rear setup suffers from lag you also run a smaller A/R, which just adds to backpressure problems at high boost.

i would sell your heads and cam and buy some 6.0 heads, maybe ported if you can afford them. id try putting th stock cam back in or get one with an lsa of 115 or higher and a duration in the 22x range. no real sense in going to big of cam on stock cubes.
