Does it sound relatively safe??

This is the goal - at least 250whp, and a break into the 12 second quarter mile time... along with daily driveability and longevity of pretty much a lifetime. lol.

Now, based on what i'm lookng for, i was at first going to just go ahead and build an LS block with some Manley i-beam rods, <unknown> forged pistons, ACL race bearings, and NPR piston rings and run 'blank' amounts of boost making anywhere from 300+whp. BUT after doing a bit of reading, and looking at one of those quartermile ET calculators, i ended up figuring out that its possible for me to break into the 12's with just under 250whp.

That's good news i guess for me, because it means i no longer have to build that forged block... since i currently have an LSvtec with ~2,300miles on it since its been rebuilt, i guess i could easily run 250whp safely from that and still meet my requirements listed at the beginning of the post on a stock bottom end, couldn't I?

EDIT: so basically... whatever amount of boost i need to push to make 250whp is where i'll tell my tuner to stop at. Unless i would need to make some room for boost creeping possibly??
