I've always been scared of forced induction, so much extra money in prepping, in getting the super/turbo, and the chances of failure/damage. And again I'm doing it for fun, not to race lol. Turbo ls is certainly nasty business and if I had that much money I would definitely consider itif you do a stroker, i would suggest building a separate engine to the specs you want and swapping, just for ease. no sense in car downtime.
there are many LS builders out there that can help you with the specs you will need to achieve the goals you want.
you could also consider forced induction. that might get you to your power goals a little easier.
