Plus you gotta take into account, the same pulley sizes will mean a drastic increase in boost. You can't drop to a 3.4 on a Gen V, thats like going to a 3.2 on the Gen III. Ontop of the Gen V you really need to know what to look for when scanning and such. The gains on a Gen 5 are well over a ported gen 3, and some even guess, that a port and polished Gen V can run close to the efficiency and power of an m112.
But if you want the Gen V, check out local junk yards first, 2004 was the fist Gen V year, so the SC is only two years old at most, any junkyard with a Gen V, i gaurantee you the Gen V will be in working order. Don't buy a new one unless theres nothing else around.

ok well i can help there i went threw the same quest about 2months ago, the best answer s ive got is, m112 vs gen 5 m112will win watch a flow chart,by quite a bit those things can run ask coolgtx, u have to get a new pulley system one for that blower, u hav eto get the lower intake mani. and and some spacer or gasket thing from zzp, zzp has blowers for 500 to 600 and the lower mani for 175 the mani as far as i know ed morad of morad parts.com is the only one that can get them i guess on order from what he told me. once u start into this its a little bit of a project and have proffesionaly installed, or some one whos done 1 or 2
u also need the throttle body adapter. u use ur throttle body or a good time to get a northstar,and a gm maf, thats a nice combo, and if u wan to get more convienant , get a intercooler, ur blowers already off, but then ur at almost 3 grand .... it gets expensive ,and seeing as a gen five flows better, u can use those high rpms more, which is rocker or cam land, so u have some options.
so blower 5-600
LIM-175
zzp spacers-?
and u use ur injectors and rails, or get nice prj ones
and tuning becomes an issue at this point get a afc ,pwertuner, or iccu
and some good tuning,
good luck
