Coil Spring for Articulation?

I have a Range Rover Classic 3.9 which I use soley for off roading.

I have removed the roll bars and fitted NRC4305 coils (17.18inch,150lbs) on the front and NRC4304 (17.71inch,170lbs) on the rear with +2" shocks.

My thinking was to keep the coils as soft as possible but quite long to increase ride height and then +2" shocks to maintain the same amount or slightly more articulation.

What is better, long and soft or short and hard in terms of ride height and articulation?

my misses reckons long and hard

Well that didn't take long, should of expected that.

Back to the springs, what are the advantages of Long/Soft, Short/Hard coils for offroad?

Short-hard are 'kit' spings, and rated to get the lift but not leave it too wallowey for the road.
Long soft is by far the better way of going, and on compers, seen three foot of 'droop' off a very-long, very soft progressive wound..... keeps ride height not too far off, so the c-of-g dont get too high.... compers dont tent to run much ride height, if you look, advantage on clerence not as helpful as lower c-of-g, when they are tilting the things over to rediculouse angles.... also intreguing is the fact that they rarely run a 'skirt' hight much over a standard defender, let alone a lifted one, AND without much but a cage above the waiste-line, they have a better C-of-G than most Landies to begin with.....
superlong springs, with really low rate, though, when you get to the point on a 'normal' off-roader that the axle has dropped so far it's hanging on the coil, then the coil is taking weight off the axle, so not as much 'ground-pressure', or weight on the wheel to transmit give traction....
Where Disloc cones are used, hanging axle gets full 'weight' as stretched coil doesn't take any of it, but you only have the axle's own weight on the wheel...
Long-soft, 'super-drooper' coils, can stilll put some 'load' from the chassis onto the axle to increase ground-pressure......

Hmmmm, interesting read.

Problem now is I knocked the engine out this morning!
Sounds like piston slap and oil in the cooling system so maybe a sunk liner?

Don't think it's worth fixing, so if anyone wants some 4 month old Steel Mod wheels and Insa Turbo Saharas then make me an offer.

Or a nackerd engine with auto box and TXB it's a 3.9 V8 EFI High Comp btw. The battery is only few months old too!

Woohoo, it lives! Decided to have a look underneath and noticed the downpipe is coming away from manifold, bit of gum gum and the noise has stopped!

did the loose manifold put oil in the cooling system
