Lets get back to the objective at the start of the thread:
shade tree mechanic, Joe the plumber V8 conversion kit
Since the Northstar was a transverse engine, all the accessory-parts are placed in a certain position. The LH2 was made as a longitudinal engine, hence making our lives (or that of the weekend mechanic) a HELL of a lot easier, instead of having to fight with wiring, making special brackets trying to align the pulleys for the A/C, P/S, and Generator.

The alternative H3 GM5.3 is a very good option, but as said power-trans-AR5 becomes a slightly more complex situation.
Need to do some more research into V8+M5+TOD conversion, and perhaps list in seperate thread (Conversion for the advanced mechanical VX-ers).
If Isuzu can produce a Manual 4WD with TOD why can't we?

Back to my books and drawing board....
