In regards to "wideblock" vs "narrowblock"
As a rule of thumb:
Turbo + North/South orientation = wideblock, 330mm between bottom bellhousing dowel pins
All others (including East/West orientation Turbo) = narrowblock, 310mm
There are exceptions to the rule though, some 4G52s and 4G54s are wideblock depending if auto or not, and some later model 4G64 van engines are wideblock also.
