Even now it's getting harder to find LA engines anymore that don't need a full rebuild, I've "moved on" to Magnums since they're the most economical way to re-power an old Mopar. I can definitely see G3 Hemi swaps becoming more popular over the next decade.
BTW after doing a bunch of research that "not a true Hemi" G3 chamber is actually a MUCH better design than the classic Hemis; all the flow with none of the crappy low-speed combustion issues which in fact was the main reason the 426 Street Hemi was killed off.
