Some of this information may not be quite right, so give me a break if I am

From the sounds of it the FWD version is the same pattern as the RWD 60deg V6 (such as the 2.8L in S10's and 3.4L in Camaro's to name a few). From what I understand the engine isn't exactly set up for normal side engine mounts. I'm sure you will figure out some way to mount it.
Edit: some more info.
