Cam for 400 rwtq on stock heads?

Cam for 400 rwtq on stock heads?
Assume an LS6 intake, long tube headers and dual exhaust, and a pulley, custom fresh air intake and no MAF, ported throttle body, HP Tuners Speed Density, and a 6,500 rpm limit. Idle quality is not a concern, the closer to a funny car sound the better to me .
Would a 228°/224° .595"/.581" 111° LSA +3° (108° IC) do it? What about the TR230/224?
If it is not possible, how close can we get? 385-390?
I know the Hot Cam is a cheap fun street cam, and the ASA can be also, but they do not take advantage of the lift possible in these engines. If I am gonna have the idle of the Hot Cam or the ASA I want more power to go with it!

To hit 400 rwtq, you're going to need a bigger cam that makes peak torque at a higher rpm. You'll need peak torque around 4800-5000 rpm and peak hp around 6300. A G5X-3 would do it with the tuning and a ported FAST 90/90 intake.

Those cams aren't going to cut it...
I would definitely suggest the t-rex to put you over 400 rwhp, I've seen that cam put a few people well over the 400's. And these cars are their dd's.

Btw, the reason it drives so good is because it has a really good tune

i had 380 rwtq before a full tune (had a small one to make it drivable) and i have MTI's C2 cam (224/224 .581/.581 112lsa) with LT's, Lanes 3'' TD's, Lid and thats basically it. I dont have Ls6 intake, TB...none of that...i hope to be close to 400 with an intake, TB, and pulley.

Do some searching and you'll find my dyno graph of my old 224/224 comp xe .568/.568 110lsa 106icl cam. It made 406 rwtq and 405 rwhp with collector extensions, albeit shitty ones (open headers) through a 10 bolt with stock gears and an m6 spinning 315s. Made 380rwtq by 3000rpm. Not a drag racing cam by any means but big block like torque for the street.
Car was an 01ss with all boltons (no fast intake at the time) and stock heads.

I did mean TORQUE . If that 224°/224° .568"/.568" 110° +4 (106° IC) did it I would imagine that the 228°/224° .595"/.581" 111° LSA +3° (108° IC) I spec'd would also, unless the extra 4° intake duration will lower torque and add horsepower. Maybe make the cam I spec'd a 111° LSA +4° (107°IC).
So, now that everyone knows I did mean TORQUE what do you think?

Nope, no electric water pump. Had a FTRA, direct flow lid, asp pulley, shaner s2 throttle body, slp 85 mm maf, stock ls6 intake (came with the car), uncoated hooker headers, about 36" long collector extensions that were 3" diameter with approximately 30% of the inside diameter blocked off with welding slag (I cut the old exhaust off a local exhaust shop did for me which was the worst job I've seen in a long time).
Also included me tuning the car by sotp and ear method as I had no wide band back then.

I would imagine that cam would get it done; however, your valve events are a little different then mine. For instance you will close the intake valve later, your exhaust will close a bit earlier and open a bit earlier. What you do have going for you is that your ramp rates are probably much more agressive then the comp xe's I had mine on. This may offset some of the difference in valve events at .050" in a posative manner to help you reach your over 400rwtq. As a side note I think one thing that really helped this cam was the open headers with collector extensions. Not just in the sense that there was unrestricted flow but also in the sense of pressure wave tuning (David Vizard article on exhausts, also his article on the "5th cycle" are good readings to understand what I mean). Set the exhaust up with open headers or the terminator boxes/resonator boxes Vizard suggests and I be you make 400rwtq with a good tune with no problem.
