G'day folks,

I'm going to post here about my conversion on the suggestion of Don(CDW6212R). I might start a little differently by posting a big pile of photos with minimal text. Then, if you're interested just ask me some questions.

Cheers,
Pete.

The subject vehicle, a '93 Vogue in reasonably good nick..

DSC05746.jpg


An Aussie BTR 95LE 4spd auto from a 5.0L Falcon was initially looked at for the conversion but, was a no go....

DSC04362.jpg


and here trying an AOD for size...definitely more promising.

DSC04372.jpg


Then I found a 4R70w here in Perth.

DSC04408.jpg


Stock 3.9 BOP engine removed exposing the not strong enough, ZF HP22 4spd auto.

DSC04525.jpg


The 3.9 BOP(I call it 3.9 POS:) next to a proper engine...an F-series 5.8.

DSC04539.jpg


the 5.8 dangled in front of the ZF.

DSC04559.jpg


No mods needed to the F-series pan.

DSC04547.jpg


The 4R70w up against the LT230 transfer box. Hardly any setback required...try that with GM junk!

DSC04675.jpg


Looking good with a dummy up under the car.

DSC04657.jpg


with stock diameter driveshaft.

DSC04668.jpg


The CAD pic of the adapter plate we would make.

rangerovertcaseadapter.jpg


Work started on the adapter.

IMG_0046.jpg


On the mill.

IMG_0075.jpg


The CNC display.

IMG_0056.jpg


Finished piece next to the original ZF extension housing.

DSC04933.jpg


Trying for size.

DSC04928.jpg


The adapter shaft, Precision ground 31 spline yoke from an '05 FPV Falcon GT pressed and then welded to a modified Landrover adapter shaft.

IMG_0052.jpg


DSC04972.jpg


Looking better.

DSC04965.jpg


Stock engine mounts.

DSC05092.jpg


DSC05093.jpg


and gone.

DSC05086.jpg


Pieces to make the new mounts of 5mm steel.

DSC05084.jpg


Taking shape.

DSC05082.jpg


Mods required to the RH engine mount for diff housing clearance. The mounts are '96-'98 5.0L Falcon Hydraulic items.

DSC05063.jpg


In place.

DSC05067.jpg


Bracket mods required for idler pulley clearance of steering box. I'm using 5.0L Falcon front dress which is the same as '91-'93 Bird/Cougar for the U.S. peeps. That's right, we don't have thermactor emissions controls here in Australia hence. the idler pulley/

DSC05074.jpg


DSC05107.jpg


DSC05106.jpg


Drive shafts made. Rear one shortened 45mm(the amount of setback I gave the engine) and the front one made of smaller diameter, heavy wall tubing.

DSC05133.jpg


DSC05132.jpg


304 stainless universal header kit.

DSC05123.jpg


DSC05165.jpg


DSC05152.jpg


DSC05200.jpg


DSC05204.jpg


IMG_0276.jpg


I made the headers to tuck up rather than go under the stock crossmember where they might hit something.

DSC05206.jpg


Here's the new crossmember I made next to the original round tube version.

DSC05208.jpg


I ended up buying a built 4R70 from Hughes transmissions. Here it is attached.

DSC05485.jpg


The view in the tunnel.

DSC05437.jpg


In there.

DSC05442.jpg


DSC05596.jpg


Deep pan is a bit close.

DSC05510.jpg


Not anymore.

DSC05539.jpg


Galvanized.

DSC05552.jpg


Plenty of clearance.

DSC05514.jpg


Trans lines.

DSC05530.jpg


Cooler.

DSC05564.jpg


Trans Oil temp sensor adapter.

DSC05634.jpg


Fuel line adapters.

DSC05559.jpg


Heater pipes with Falcon heater tap added. Range rover does not have a tap in std form which might be ok in a cold country but not here! These line up nicely with 5.0L Falcon orginal steel heater pipes on the engine.

DSC05582.jpg


Ford racing 90 degree oil filter adapter.

DSC04817.jpg


BC Bronco's HO adapter plate is lowest height option for this conversion. I do have a GT40 lower and Explorer upper to go on but that's later and it's 20mm higher so it's going to hit the bonnet.

DSC05461.jpg


Stock 5.0L Falcon water crossover tube and custom bracket.

DSC05548.jpg


after mods.

DSC05580.jpg


Boss style covers with the "Ford Racing" and "Boss" milled off and a Landrover green paint.

DSC05601.jpg


Had to cut this down for rocker cover clearance.

DSC05647.jpg


DSC05648.jpg


DSC05664.jpg


Modified 65mm EGR spacer for bonnet clearance.

DSC05665.jpg


DSC05669.jpg


DSC05670.jpg


DSC05668.jpg


Ported HO upper. I also port matched the adapter to the upper and lower.

DSC05673.jpg


Falcon air box modified.

DSC05687.jpg


DSC05706.jpg


Exhaust taking shape.

DSC05714.jpg


DSC05715.jpg


2 1/4" twin.

DSC05739.jpg


MLPS Heat shield I made from one off a Falcon.

DSC05716.jpg


Looking like it's meant to be there I reckon.

DSC05731.jpg


Original shifter hole. I fitted the rivet holes with nutserts.

DSC05749.jpg


Originally I ran it with the std shifter in reverse pattern.

DSC05747.jpg


I have a ZF six speed shifter from an '08 Falcon which is much nicer and has the Tiptronic feature which I'm sure I can adapt to the Optishift controller.

DSC05833_zps8f55292e.jpg


The linkage however was quite time consuming to make.

DSC05835_zps0f1c96c7.jpg


DSC05836_zpsc36b6fdb.jpg


DSC05773_zps17e90593.jpg


Made this using 2mm stainless.

DSC05847_zps8e846764.jpg


and the rest is 1mm.

DSC05846_zps4b14a575.jpg


DSC05843_zps2acb036b.jpg


I've used a '93 Falcon EECIV from a GT/Sprint Falcon(basically a '93 Cobra type calibration) with EV6 Ford racing 24lb injectors and a '94-5 type 70mm Cobra MAF. I use a Moates 1/4 horse for tuning which at this point I haven't really done other than changing the displacement to 351 and turning off EGR.

DSC05644.jpg


The Harness is 5.0L Falcon spliced into the Range rover one.

DSC05646.jpg


OH yeah, here's the GT40 lower(an Orginal Lightning piece this one) and the Explorer upper.

DSC04878.jpg

REALLY nice! Great camera work, too.
What size was the original engine?

Bill, the original engine is a 3.9L v8

I love it!

Since he won't get rid of it, I've been trying to get my dad to put a real engine in his '91 County SWB for a long time. He's gone from the 3.9L to a 4.0L and now the 4.2L which are all crap IMO.

Great work!

Great job Pete, there's a bunch of really nice fabrication in there.

The 3.9 engine was an old Chevy development wasn't it? I heard about it on Top Gear, GM created it but didn't have a use for it back then. So Land Rover got the rights to it and it's been one of their oldest engine lines.

Excellent job! I love it all.

Makes me want to pick up an older RR SWB for a project.

Thanks Lads, Glad you like it.
Yeah they call the old engine a BOP (Buick Oldsmobile Pontiac).The damn things slip liners if you look at em sternly and it's exactly what mine did....Rubbish engine!
Something to note; the 351 is the same width and shorter in length than the 3.9 POS engine. It's only the height that is greater although the EFI intake has alot to do with that. This vehicle is made for this conversion and there's a lot of cues for other left hand drop transfer applications.

Pete, where did you get those valve covers? The pictures make them look just like Cleveland VC's, which I love. If those are easy to get and fit nice roller rockers, I think I'd like those. Are they aluminum, and do any come for fuel injected cars(one side sealed with no holes)? I prefer the stock Explorer type fill tube etc.

Here ya go Don,
Mine are the M-6582-BOSSP version. They say; doesn't fit EFI but, that's really for people who don't want to do any work putting them on. I've got the PCV in one and the filler in t'other but there's no reason why you couldn't block one up or weld it shut. The Cleveland/Boss look is what i like about em too plus, they look similar to the flat top covers on the 3.9 POS so at a glance people might not recognise the engine is any different. The remaining Ford logo is pretty hard to see with all that other stuff on top of the engine too and the Landrover Green in there probably throws them off too:) See you can get FE looking Valve covers for your windsor heads as well...

00 Sport FI, 03 Ltd V8
1962 Olds F-85

In the early 1970s during the fuel shortage I purchased a 1970 Jeep Wagoneer that came stock with a Buick 350 V8 engine. I was stationed at Mather AFB near Sacramento, CA and my wife and I wanted to visit my parents who lived in Oregon. We purchased a 1962 Olds F-85 station wagon with the 215 aluminum V8 so we could make the trip on minimum fuel. We kept it for several months while I rebuilt the 350 V8 that had 80,000 miles. I suspected that the 215 aluminum V8 would not hold up very long. Instead, I purchased a Jaguar XJ6 for my wife. I kept the Wagoneer for 24 years before selling it in running condition with the original engine.

I am very impressed with all of the excellent engineering and craftsmanship you have demonstrated in your engine/transmission swap. The 5.8L/4R70W would be my preferred drivetrain for my 2000 Explorer Sport. The 5.8L has excellent torque and the 4R70W is a reliable, robust transmission. However, the upgrade would probably take more effort than I am willing to expend. Also, there would be a weight distribution and a fuel economy penalty. I enjoy having five forward gears to select from. A supercharger (difficult to acquire) may be a suitable alternative and less work and issues.

How much did your weight distribution change and did it adversely affect the handling of your Rover?

What year and model of vehicle did the 5.8L come from?

I'll have to read about the Moates QuarterHorse since control of the 5.8L was one of the issues to resolve with a 5.8L upgrade to my Sport. Stock engines with the "trigger wheel" are hard to find.

Thanks man,
There has been a slight handling change with the extra weight but I did manage a 45mm setback which helps. Not that the handling was great anyway. This car already had the air suspension removed when I bought it and the springs fitted are reasonably stiff. I measured no difference in height of the front end after the conversion. The handling is now much better than before the swap since I've just fitted Bilstein shocks all round.

I've just discovered a rear main leak so while it's out I may fit the ally heads/GT40 intake and use a small retro roller in it. That should shave a little more off the front end.
Certainly, If you already have a 5.0 it would be far easier to stroke it or blow it or both.
The engine is a '91 F-series job. I would have preferred to use the entire stock intake as it's long runners and dual plane design make for the ultimate torque but alas the height is ridiculous.

We've made a couple of trigger wheels for pre-EDIS engines including clevelands which are of course very plentiful here. We machine an area on the back of the balancer and press fit the encoder wheel.

Btw there's plenty of meat on your stock balancer to take it down from 50 to 28oz I reckon. SO you could just machine that weight down and use it on your 5.8 engine.

Nice, I like that balancer, it's better than mine. I had to deal with a place that over charged, and didn't secure the trigger wheel properly. After having it spin while being balanced, I had a local shop pin the trigger wheel in place, and then make a second one for a member here.

Where did you get that trigger wheel, the one with larger holes in it?

I like it, too bad it's not seen when installed.

My cat follows me when I'm in the kitchen.

It's probably gone rusty now anyway Don.
My cat follows me everywhere and even helps(her idea of helping is to lie down on whatever I'm doing:)

Hey guy's, A question for you; Do the Electric shift motors on the various Ford transfer boxes have lots of torque? LT230 transfer boxes are pretty damn hard to shift at the best of times. Especially the diff lock. I'd like to do an electric shift conversion.

I don't know how strong they are, but the same shift motor on a 91-01 Explorer is the same part used on the big trucks TC's, the Expedition and Navigator. The BW 4406 TC is big and common, and we use that to make the V8's a real 4WD. It uses the same shift motor. They can be had for about $75 new, but lots are out there for much more, including used. Ignore those.
