Defender 3.5 v8 with holley carb???

I take it this carb wasnt standard......

correct.

The original fitment would have been (depending on the model year) twin Zenith strombergs or SU's. 114hp rising to a heady 134(!) but plenty of grunt.

So the Holley is an upgrade? Are there any bad side effects of having this carb?

nope - its a common enuf carb. Fixed jets.
May not like extreme angles of attack tho.
Which one is it? 600/650?

I was on a play day recently with a lad in a 90, I think he said his had weber(s) on it.

Whichever way round, it used to struggle up steep hills because I assume the floats would get confused, which was not ideal.

Yes,they are crap off road,much better with Strombergs,better still with EFI.

lol, How steep are we talking? I'm mainly gonna use it on road to start with, maybe tricky conditions like snow etc, Should be fine for that?

I would like to do some green laneing in it eventually though... but not any sort of competitive climbing lol

pretty steep stuff, got much worse when the engine cut out though!

Quite a few people have written about wanting to change there efi for carbs, why is this?

Mostly because they are too lazy to spend the time to understand how it works,or they are just stupid.Efi,esp the 14Cux on 3.9's is very DIY friendly and there are loads of cheap bits around and lots of info.

I have 14cux on my 3.5 and i managed to diagnose a fault/check everything else with a multimeter and a helpful website.

I think it's a great system, it uses far too much fuel, but if you keep everything sealed its been great to me off road.

Which uses the least fuel? Carbs or efi?

Not sure, I'm gonna have a look shortly, can you tell visually?

Efi should be most fuel efficient as it is electroonically controlled - but only if everything is in tip top condition.

from the number shown on the choke housing, you can identify what carb you have.

I handsome new info. Appenrtly it's a range rover sd1 engine and an auto gear box!!

this might help ya.
