Quick update:
I took the motor back out halfway and took a hammer to the passenger side firewall just above and to the left of the tunnel. The cylinder head for the m30 will not fit if you don't bang it in a good 2 inches. the more you feel like hammering, the better the engine will go in, but there is always too much of a good thing in this situation.
I got the motor back in and muscled it (literally, i was working alone) into engine position 3!!!!!!
Best sound ever when that big motor settled down on the right mounting point. even in this position i'll be amazed if that radiator will fit. there is very little wiggle room. my urethane mounts may come back to bite me in the ass as well because it looks like the motor won't clear the hood... but i guess we'll have to test it.
i get the radiator, throttle bracket, throttle position sensor tomorrow so if all goes right and i can figure the wiring out, this car will start tomorow.
then on to the cooling routing as well as differentials and driveshaft stuf.
