I've got a good 4 to 6 inches between fan and rad. So moving 2 inches forward we be plenty in the rear without getting to close to rad.

Leaning towards a small mod to each side of firewall. Only need about the size of a pack of cigarettes on each side. And since I have a bunch of holes to fill on the firewall anyway, it wont add much time to the project. Plus everything else can stay as it was from factory.

I just like to have options.

If I was to move engine forward I would just move rear crossmember forward a few inches.

Already using side mounts on the engine that are not attached to the frame yet.
