It's the same block, and all the mounting points are there to use the RWD mounts.
Bruce, buy Buck's engine, then check out Morad Parts Company on eBay for a 4t65e-HD trans, OR if you want something a bit tougher than the usual Getrag 5spd, look for an M4 manual 6spd from a G6 GTP.
Anyway, welcome, good intro, +rep.
EDIT, just thought, the L67 BLOCK will fit just fine, but the S/C will NOT. There's nowhere near enough room against the firewall. The only guy who has done it had to do a nasty hack job on the intake side of the S/C. If you want the L67 in an F-body, you'll have to go turbo or CSC.
