I would be loosing a lot if the motor came loose and killed a set of 205's. Keep in mind this thing's gonna spin up to around 7200 or so. If need be, I have an ls1 intake laying around I can use. I just gotta get some fat injectors for it. 
Everyone is screaming for someone to stick a monster cam in a 5.3. It's fixing to happen.
Someone you mentioned, I'm not saying who in public, I wouldn't put any stock in what he has to say. If you want details, PM me.

Save up your pennies and go with a 402 ci LS2 with 225 AFR heads and a carb setup.Then that cam will be pretty doscile.Maybe 650 NA horsepower then add a 200 shot to put it in the 10s.

if you put a ls1 intake with that big cam in a truck you really going to need a 5k converter cause you will lose even more low end.
just my 2 cents i think with that cam you will need @ least 4.56 gears or 4.88 and a 3k or 35k stall. i will love to see the out come.
IMO---FLYER'S CAM STOCK HEADS PTC 3500 4.56 GEARS SHIFTING @ 7K.I COULD CARELESS ABOUT DYNO #,I WANT TO SEE IT GO DOWN THE TRACK.THIS COULD BE VERY INTERESTING.

these theories you are speaking of have been tested thouroughly. there are sevral people on here that have done the swap. the low end is the same. they gain some hp up top. but you are driving a truck. a truck doesnt weigh 3700 pounds and shaped like a rocket. you need torque to get these pigs rolling. the camaro guys even like the truck intake for the low end torque. and there have been several flow test to prove the truck intake works. imo. you may gain some hp up top above 6000 rpm's. but i believe that the 300 or 400 rpm's above 6000 is a small gain for the truck intakes gain from 700rpm's up to 6000. good luck.

Can you give me a link to some of these results? I'm not interested in the magazine articles, I have seem them. I know Blacksheep saw very decent gains with the LS6 swap.
Up above in this thread, Reddevil and 02sierra are mentioning how the LS1 intake shows an improvement in "high rpm" power. The LS6 intake has been tested thoroughly showing gains across the entire powerband against the LS1.
What I'm getting at is it sounds like there is a huge amount of heresay going on. Things are not adding up so it's definetly worth a shot.

I got the cam in ... and from the setometer, it's still pulling hard as hell at 7000. I didn't think it would fall off at 6200 like predicted. I'll try and get the G-Tech on it to show the G's. It will also show a HP/Torque curve, but the actual numbers won't be accurate.

Flyer, horsepower "should" peak at or around 6200-6400 rpm.
I never stated power would fall off but, what will happen is that the hp curve will flatten out tremendously.
Why?
Because the intake manifold has become a significant restriction at this point. As stated previously, this camshaft is large enough to peak at 7,000+ rpms given the proper induction.
Here are some examples of these 62/64 hundred rpm peaks I keep mentioning.
