(So would the TSP 233/239 112+4, but I don't want to confuse the issue...) Check out this F14 video from LS1sounds:

only reason i dont want FM14 because the peak power is too high and it doesnt have near as much down low as the 228R and yes 4.10s will be coming very soon TECH Enthusiast

Are you guys running dual springs with the 228r? Wouldn't it be harder on valvetrain since it has xer lobes where the f13 supposed to be not too harsh? I was thinking about f13 but my car is dd and mostly street car so maybe the 228r would be better? thanks

So the 228R is the best for a daily driver? Mine won't be a track car, mostly stop light and highway racing. I actually don't even race, more or less stomp it on the on ramp or on rural roads for my own enjoyment.
I am running a 4000 stall converter and will have 3.73 gears. People have steered me towards the 228r, but with my stall and gearing would I not see more benefit from the MS3 or F14 on a 112 LSA?
I am upgrading my lifters, pushrods, using dual springs, double roller timing chain, ls6 oil pump and 5.3 stage 2 heads, so I'm not going to be worried about revving to 6800rpms. Would the 228r still benfit me more than an MS3 or F14?
I'm not trying to hijack the thread, just trying to get as many opinions as I can on what cam would work best for me.

well my ls2 with fast 90, 232-234 comp xer (torquer2), i made 447 rwhp, 426 rwtq, but i have 243 heads, and 18 more cubic inches. but from what i am seeing cams with 235+ duration, arent really making enough power over smaller combinations, to justify the crappy drivability. i think i wouldnt go any larger then 232 duration cam on the street, but thats my own .02 cents

The tune isnt on point at all for the f13 and i expect it to be much better once i tune it, but i feel i should've stuck with the f10. I guess i just jumped on the band wagon because I was impressed by the peak numbers everyone was posting. That made me stray from my original goals of having streetable power..the f13 was still pulling at 6700 
If your not going to spend alot of time at the track or in the high rpm range, id go with the 228 112.
