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 [bigrolf]

Make that two!🤣

I was looking at the trigger wheel in the dizzie that it wouldn't run properly on.... there is damage to one/some of its teeth. I'm guessing the fuel regulator died a couple of weeks ago... but because it always started instantly, it flicked over to LPG almost instantly, so just ran rich for a few seconds until it cleared the fuel out of No8. The second it didn't start instantly (the trigger wheel issue) ..... it was all over. I hydrolocked it :(

Maybe i love the old way too much but surely there is an engine joint remaining in the Rat who can re-size conrods. That is: correct length and no twist.

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!).
