ok
i myself am running a 440 in my truck and turn it 7500-8000 every time down the track. with a mp .484 hyd cam.
Really...sounds like your tack might be a tad off...

first run in this video it turned 7800 rpm whole track and peeked to 8300 at the other end of track when carb stuck. second run was in a pull off with heavyer weight and it turned 7600 whole track. yes i perfectly understand diablos point and i know and have talked with him a bunch the problem is i am running a final gear ratio of 9.16 to 1 right now. mine being a standard also and his is a automatic. plus we both have 2 diffrent types of sleds we pull. his is more of a show sled with the weight dropping on you 3/4 down the track, where as ours is a transfer sled.
and this is my fathers cast crank, ly rodded 440 turning 8500 rpm

I thank everyone for their input. I am trying to digest all this information. I will likely PM for more detailed info. I must clarify a few things though. 4 Speed NP435 3.34 second gear.Center force dual friction clutch. Tcase is NP205 1.98 low range. Gears are 4.56s trac locked dana 60 front 1330 u joints. Hate to say this but its a corporate GM rear detroit locked 14 bolt 1350 series u joints. I am stuck with these parts  they have proven to be reliable for me. So my alternate gearing must come from tire sizes unfortunately. But I have a quite a few choices, FRIENDS are great. I have 5 440s one 400 but my intake and headers are for RB. I know the rods are the weak link at this desired power level and RPM. Any opinions on what cams would produce both the torque and RPMs requirements? The compression will likely be 9.8 to 10.2 its currently 10.8 with eddie heads. I have not done the math just know what it was from when we built it for my brother. Im getting his leftovers about time ju ju smiles on me.

What rules does the cam have to fit into?
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

AND TO THE POINT. Im building a 440 that needs to rev productively to 6500 and yet make 350+ pound foot of torque as close to 2500 rpm as possible.
The rods are stock LYs with arp bolts,pistons are aries. Heads will likely be stock mopars ported with templates from mopar. Intake is Weiand dual plane,750 Q jet, headers mopar electonic ignition, high 9 compression.
The truck is a 4 speed ,4.56 geared,37 inch everyday tires, 33 inch for pulling, short bed 4x4 dodge.
Ok I punched in the numbers and threw in a solid grind cam with my own specs of 280 @ .050, .600" lift, 106 LSA.
Keep in mind this is using the parts that you specified, 9.8:1 compression, ported 452, and 1.875" headers that are 38" long.

I shift my mild 906 headed 440 at 6200 and trap about 6300 to 6400. It seems to like that rpm but I do agree most 440's dont need to go over 6500 unles you have great heads with alot of cam and some good rods. Ron

280* @ .050 with 9.8:1 compression 
I would think that's outcamming your compression by A LOT! I don't think you're going to come up with very good low end torque #'s with that combo. ??

I'm not sure all tachs are incredibly accurate. My 484 hydraulic cammed 440 Demon would pull 6400 rpm all the time. After a few years it seemed to me like the tach went higher, so I would hit the recall... 7100 rpm.  That's with no changes, nothing. Then it would pull to 6400 rpm for a few months, until it would read 7100 rpm again. It was an Autometer tach too, not an Autogage. Left me baffled.
