Hey you asked for BIG cams...
I saw a list like this on here somewhere before, was interesting.

PLEASE TELL ME THAT YOU CAN NOT FIT THAT IN A STOCK CUBE ENGINE
FMS 255/261 .731/.738 108 LSA
I went 10.11 NA with my 346 motor and I run 9.6x NA with my 408.
Interesting comparison:
MOTOR: FMS 346cid LS1 (Stock LS1 Block)
RWHP: 485ish
BEST ET: 10.11 @ 133 MPH
RACE WEIGHT: 3250
Same car..
MOTOR: FMS 408cid LS1 (Stock 6.0 Iron Block)
RWHP: 585ish
BEST ET: 9.68 @ 139 MPH
RACE WEIGHT: 3350
With the 408 the car is 100# heavier also, its a no brainer the 408 is MORE FUN!!
Right now I'm beginning another FMS motor project, I'll post more when I get some decisions finalized.

FAST LSX 90mm intake, FAST 90mm TB
FMS/Meaux Heads, they are LS6 heads with 2.055/1.60 valves
I used K-motion double springs and T&D shaft rockers
I shift the motor at 7400 rpm and trap at 7400
Drive train is a TH400 with a TCI 5k Stall, Moser 12 bolt and 4.56 Gears, MT 30x10.5x15 Tires
Everything on my current setup is exactly the same except I changed the short block to a 408 iron block with a bigger cam. I still use the same intake/heads/valve train/drive train etc.. I did have TCI tighten the converter and I also put in bigger valves for the 408 2.08 valves now.
I will be going to a sheetmetal intake on my next motor, I believe as does Allan that my current 408 can't get enought air through the LSX90.

I can't even begin to imagine how hard that must sound in real life
