Stay as far away from Hennessey as you can. A simple FRPP blower kit would be more than enough power & pretty much any shop should warranty their work (labor) should an issue occur.
From what I have taken in, it is the rods and pistons that are the weak link as far as rotating assembly goes. The stock oil pump has been known to grenade at high power levels also. There are plenty of us, including myself, that are running around with 600-650 rwhp and we are doing good thus far.
Anyone knows how much does it cost to upgrade fuel pump gears?

I know of someone with about 750RWHP on a stock motor.
Power level vs life will be dependent on how you use the car as well as how you maintain it. Id put money on the guys with twin screw blowers having premature failure before centri and turbo guys because of the instant torque spike off idle. That's pretty much a rod's worst nightmare and that is the weak link in our rotating assembly.
Yep, and a single stage nitrous kit surely isn't going to be very friendly on a stock shortblock either.Link to shops that provide 3 year/ 36k warranties? Not trying to be a dick I've just never come across shops like that, can't say I've looked though as I do all my own work. Do the FRPP or Roush kits have a warranty if they are not installed by a certified dealer?

Currently 600-650 seems to be the limit ive got a roush tvs pushing 575rwhp at 8.5 psi but i just switch ed to a new pulley and am at around 12.5 psi and will have dyno numbers once it cools down
Shocking, a ford motor with weak rods and pistons!!
How are the rods and pistons weak when they withstand 600whp for a while?
I think you're forgetting that the motor was designed to run at 412hp ... they didn't design the motor hoping that some guy would dump $10k worth of mods, and push another 300whp worth of extra stress on top of this motor.
The rods were most definitely designed to handle more than 412hp. They probably were designed with a factor of safety of anywhere from 1.5-1.8. You don't sell a piece of machinery already operating at its performance limit. No Ford did not intend for everyone to run out and strap on a major power adder and have the motor survive but there is most definitely room to grow.
