Somewhere down the line you'll have to find u-joints that will mate your rear driveshaft to the isuzu diffy. Front too, if you end up changing t-case. Universal frt. engine mounts used to be easy to find, the trans may need fabbing. I think I recall seeing plastic mock-up blocks that you can buy, to use as a quick tester to see if it will even fit. Either that or you'll have to come up with some kind of block just for test-fitting. I'm wondering how the accessories etc., will fit with our (low-profile?) hood. Also, depending on what body style the engine came out of, the accessories have different mounting locations, at least they used to between vette, f-body and caprice.
