The engineers were not clairvoyant so did not know that one day in the future V8s with a front oil pump would have a longer crankshaft. So they are not forward compatible.
You know I have posted this pretty exact post about 15 years ago.

You can put Vbelt timing case and accessories on a 4.0-4.6L Block by using a spacer but not vice versa.

Look I would guess that NZ would have a die to clean up the thread on the radiator. I would have it rodded at the very least anyway.

Then a couple of oil cooler hoses and bob's your aunt.

It's your fault that you used to alternator on a tractor. Surely you knew one day that the LR hex would get you.

I guess if the crank is OK in the bent conrod engine you could switch cranks, but there lies madness. ( and expense) There is always some detail that will derail you, but AFAIR the bearing sizes are the same.

Oh, I'd be happy wiht a nice 4.6 if someone has one kicking around that doesn't have liner issues

The first motor I built with the help of my grandfather was a 1500 VW flat motor and I had the rods done in Geelong for next to nothing based on his input.

The classic Chev rebuild DIY book has a few pics of crazy bent rods that were resized with no probs. Something to do with the metal they are made from, from memory.

I have never heard of such a thing!

Land Rover Parts - CON ROD - 3.5+3.9 V8

it looks like all the V8's (3.5, 3.9, 4.0) have the same conrod. I"m sure I'll be able to chase one up locally without many dramas (Well I'd hope I could either way!).
