Has anyone done a swap to a 4.3L that has had the 3.2L Auto tranny?

StinkBug has a 4.3 in his Amigo, right? But I don't know which engine/tranny he started with.

After reading on Bruce's site it was looking like a whole drive train swap was necessary...

I believe so. The back of your block has two bolt patterns. The one you're using now, and one for a GM 60* engine. So the interchangability is backwards from what you're wanting to do.

Looking for an option for a decent motor swap to get rid of the 3.2 SOHC.

3.5 Direct Injection!(?) I'm only guessing that the 3.2 and 3.5 are physically interchangable.
How about that supercharger on the main Isuzu page here at the wire?
