Where do you find these 14 sec bolt on SI drivers? I've never seen one break 15.4 at the track, but then again most people can't get an LS into the 15's, crappy drivers everywhere. Do the crower stroker kits allow you to retain the same r/s ratio? I haven't heard much about them. As for your swap, the only real pain in the ass is converting to cable. After all, you can always throw in a GSR block later, stroke that to 2.1L . Good luck bro.
