I have heard this is possible on several different occassions. I don't know if this has been asked specifically, but what would it take? I have not seen anyone pull it off.
I was thinking a built 346, forged rotating assembly, good heads (WCCH or AFR??), GT2-3 cam, 90mm TB, small pulley, alcohol inj system, longtubes....what else? Where would that put down power wise?
BTW, I know that peak power is not the most impprtant thing, but the more power you can make, the more power you cam have "under the curve"
If this has been addressed just put up a link.

 

600RWHP with stock 6.0L displacement is going to be tough without n2o.

 

so its not possible.

 

talk to whitt1, he may have some insight

 

I would buy a Radix if 600 rwhp was possible w/a 5.3.

 

you will get diferent answers from diferent people on this site. some are more optimistic than others.

from the data i have seen the hp gets prety hard to come by above 500rwhp. whitt said he got over 600rwhp(not sure of the exact number) but even he admited he thought it was some kind of a dyno spike or somethings of that nature. if you really want to push it that hard than a turbo or procharger or waiting for the mp122 would be the way to go. the livernois kit could be bolted on and run ~650rwhp prety easy if you have the right suporting equipment.

flame suit on....

 

Is this with the T-76 turbo?

 

yes but a gts76 would be even better. you will need more part than just what comes with the kit to be safe at those numbers. large injectors, more fuel system, tranny, built motor eventualy, custom tuning.........

 

realistically the Radix can put down 500-550 I would assume

 

sureit can, with the help of a cam, 90mm T/B, 3.1 ish pully and a good tune. on a 5.3 of course. hell you can even do it without headers just a good cat back
