GM did such a good job with it's Direct injected V6's, just imagine what a compact 5.7 DOHC would do.. though that might be heresy

The two are mutually exclusive. Take the physical dimensions of the 6.2 OHV vs. the much shorter stroke 4.4 L Twin Turbo BMW V8 (as shown by GM when introducing the C7). Latching big W-I-D-E DOHC heads onto a V-configuration engine adds to its width.
It would be
physically impossible, with matching stroke capabilities, to make a DOHC the same compact size as the LS/LT family of engines. As Ford has found out. That's why the
5.8 DOES NOT FIT the S550 engine bay.
How much wider is the GT 500 5.8 then the LSA/LS9? Considerable.
