ls3 418 forced induction

Is anyone running an ls3 with forced induction on here with major success? Im shooting for 1000rwhp plus and hear good and bad everywhere. Would it be a plus for me to go with a 416-418 ci ls3 or would i not see a diffrence going with an iron 408? Leaving weight out of the equation of course.

So if you had a choice for f/i and around 20 psi which would you choose and why? Shooting for major reliability and no my pockets are not super deep so hopefully i can keep this motor with in a reasonable price range

Anyone running a texas speed shortblock with boost? How much? How much power have you put down? Any problems?

Thanks for the help

I think either block with be fine with the appropriate rotating assembly, but I think your main issue will probably be keeping the heads on the car/pushing water.
