Surprised in all these years noone actually fabbed up an intake and fuel rails for an Eaton M90. The M90 found on the GM 3800 V6 would probably be the best (design-wise) with a rear inlet, rather than top inlet found on the M90 off the Ford 3.8 Thunderbird, solves hood clearance issues right there.
Not to mention the ported and modified housings and snouts and modular pulley systems the GM aftermarket provides.
