It does appear all these engines share the same platform. The 4.3L is the 4HF1 which is non turbo and the 4HK1 is the 5.2L turbo. Plenty in between.Thanks for the advice.
I am planning to swap 4HE1 to an old body style Ford F250 someday.
Anyway, do the other engines in the Isuzu "H" family can fit the 6HE1 housing I mentioned? (I've seen trucks with 4.3, 4.6, 4.8, 5.0 and 5.2L variants of that family)
Here are some random pics of the Land Rover engine bay with 4HE1 installed:Someone in Australia has fitted a 4H, IIRC 4HE1, into a Land Rover and it has turned out a very nice conversion. The rear facing starter didn't seem to present a problem for the foot well, just a mod to the transmission tunnel.
Although we drive on the right hand side, Land Rovers have narrow bodies compared to many other vehicles, about 1630mm (64") outside body width. I would have thought it would be easier with many US vehicles.
I'll see if I can find some pics of his Isuzu conversion.
