heres some info on axle codes
Gears and Axle code - Ford Bronco Zone Early Bronco Classic FullSize Broncos

 

I really liked the G220, was a beautiful car. But it got smashed a couple of weeks back. I also have another here which I was using for parts. I contemplated putting the 3V motor into the F-truck but the 351 is quite good.

Thanks for the info on the axle codes. I didn't get to have a look under there today unfortunately. I was out in it for a good part of the day then got busy before I got a chance.

I did however have a pair of these arrive today, going to put injected LPG on as I have a kit here which I was planning to use on the G220. I just needed these to finish the kit but will now use it on this beast instead. Should be a good upgrade I think!

grabs some pics of the install m8. We luv pics here. I might learn something on the way

 

Will do, be happy to!
I'm sure LPG, or propane to other parts of the world, is an unfamiliar set-up in a car.

I'm waiting on a replacement air box to arrive as the in it has gone bang from an LPG backfire. Hopefully with the injected LPG, that wont happen again.

 

Brian? Is m8 like text slang for "mate"? Being a Pirate myself my crew and I use the term "mate" and or "Matey" regularly.

AshCook? Please tell more of the LPG conversions. Is Propane conversions available and plentiful for most cars as well? LPG is non existent around here. I am planing a trip to Disney World with just me, my boys, Mikey our Queensland Blue pup and of coarse the Bronco. Once in the lower 48 LPG would be plentiful.

I would think the LPG would be just fine on the Freeway but how would it be for crawling slow off road? Or towing? I have ran propane and understand it. But the LPG is natural gas, right? And just wondering if it is hotter than propane or not. Or is LPG propane? IDK

 

That's right, LPG is Propane. I'm sure the mixtures may vary a little as I know even here depending where you buy it depends what blend you get. Some run crap, others run awesome!
I think when you buy Propane here, that is in its pure form. But you know how our terminology can vary around the place so I'm not 100% sure on the differences.

Here in Aus, it has been used on cars for a long time due to the cheap cost per litre. I'm not sure exactly when it began to be used but I know I've had and seen plenty of cars from the 70's that used it. It has always been popular on our big engined cars, especially on Fords. Fords really like it, they run very well and efficiently on LPG.

The engine does use more LPG over fuel to get the equivalent mileage. But due to the much lower cost of LPG, LPG has been the choice. Usually you would expect running LPG to cost you half that it would on petrol or even less. So you don't mind using a few more litres/km if that is the case. Especially when a truck like mine has 3 LPG tanks, can hold 210 usable litres, takes you a long distance!

At the moment, my truck as a wiring problem with petrol so petrol wont switch on and only LPG is working. You can use LPG just as you would use petrol, it performs just the same. LPG even has a higher octane rating.
The down side to running just LPG cars, is it runs dry, and on a car not set-up for that, it can eat out valves. Its a good idea to run petrol every so often to wet things up. On cars designed to run straight LPG, engine design prevents this. Ford have even been selling straight LPG versions of the Falcon for some time. Very popular with taxis, business/reps, and commercial vehicle owners.

There are more cons with certain set-ups, I'll get some pics of mine and show you some reasons and how things work.

 

Yes m8. m8 = mate.

Ash, wouldnt it be better to spend your coin on getting your heads (valve seats) modded so you just run Gas. Not trying to put you off , but how much is it going to cost to get your LPG/Fuel set up working properly. Apposed to the head work.

 

It has cost me about $220 for the extra parts for the V8 I need over the 6ycl parts I already have. I had the full injection kit, worth about $4500 if you walk in and ask for it to be installed. I removed it from a damaged car which I purchased specifically to get the kit. I sold the rest of the car in parts which then paid for itself plus a little bit. So overall, this conversion will be a freeby.

I do all the work myself too, it is fiddly and can take a while, but if I were to pay someone that would add up to quite a bit so I can save there as well.
I have the same kit on my wife's Territory, I put it on that car as well. It's a good kit, it's the OMVL Dream XXI-N.

The engine was supposedly rebuilt about 50 thou ago and also to suit LPG. Whether that is true or not, I don't know. But it does go quite strong, especially with 330k on the clock. I would not call it a tired motor at all.

 

LPG is more expensive here than gas. It's made in the lower 48 and barged up here. So we pay a lot for getting it shipped in. The only rigs here that use it are the Propane delivery trucks as they run on it. So it wouldn't be cost effective to run it here. But it would in the lower 48 where I think it is cheaper than gas.

 

At the moment, LPG here is 79.9 cents per litre. ULP is $1.55/ litre. It was only recently that LPG had jumped from 59.99 to 79.99. Which is a massive increase. It actually jumped to 89.99 at the time of the jump but has since dropped 10c.

At 59.99, it was quite good. Where it is now is border line but on a big truck that LOVES petrol, LPG is still the wiser option.

I'm not an old bloke, just turned 30, but 12 years ago when I got my first Falcon ute, a 6cyl 250 4 speed, LPG was about 30c/litre. $20 would get me about 400km's and would last me a week. Now my family car costs about $60 to fill and is getting mid 300's per tank.

 

Got a heap of pics so will start with this. I haven't had a chance to cross reference the details yet, just uploaded them and wanted to stick them up first.



I had lots of help getting that shot



Now for the LPG shots. Here are the tanks





And more help



Here is the system in the F150 engine bay. You can see the converter on the far right, the lines going from the converter and splitting into two where they go into a mixer in each of the intake pipes



The converter



The mixers. This is a big bottleneck and a big con to this system. It reduces the ID of the intake pipe drastically and really chokes it. It effects the performance of both LPG and more so petrol



This is the OMVL injected system which is on my 6cyl Ford Territory. It is the same system as to the one I will be putting on the F150. You can see it also uses a similar converter to the left. With the V8 it has the option of running twin converters, one on either side of the engine bay, but that is more so for high HP engines. I think that would be overkill for the trucks engine.



Here are the injectors, a very neat fit. They are group on 3's for the 6cyl, that's why I needed groups of 4 for the V8.



And this is a manifold with the brass nozzles where the injector piping attaches to. Compare this to the older mixer style in the intake, this injected system has no bottleneck and no restriction in air flow.

 

From the link supplied, I found my front diff reads as

Gday Ash and welcome mate (m8)!

Nice looking truck, glad to see it being used as Henry intended - as far as your interior and that goes, yours is identical to my mate's 1984 F100 which is the same as the Bronco here. The wiring in my '74 is the same colouring as his, and matches the diagrams in my old XF manual, as well as a lot of the same wiring (for lights etc, not engine) as my EF's manual. Ford haven't changed their formula of Yellow = +12V, Red/blue trace = starter etc etc for a LONG time. I think he said it was the same in his '56 before he ripped it all out and rewired it.

His '84 is also on dedicated lpg. 351C with dual tanks (180L or so from memory), I think a 300 or 330 converter and he's bolted the mixer directly to a Holley 650dp base plate, which eliminates a lot of the restriction you were talking about. Not that it will ever compare to your lpg injection as far as performance, but it's miles ahead of having the mixer separate and feeding into the normal carby throat. Just thought you might've been interested

If you're interested in pics of my mate's setup I can grab some next time I see him. Just let me know. Also - where in Aus are you?

Cheers take it easy!

Hey Jais and thanks!

I had a feeling XF equipment was going to come into play. Something about the sucky way the wipers work gave me a hint there, ha!
But that's good in a way, XF's are quite simple and I know them quite ok. My last project car that never saw an end was an XF ute that I put a 351C into and ran straight LPG. I ran the same system as you mentioned, a 425 Impco on a Holley baseplate. That thing went very well. Would have no problems losing the rear tyres in 3rd.
I was even about to step mine up and run a Weiand tunnel ram and twin 425's. Had all the stuff there but my Mustang took priority so I parted the car out and flew to the US.

I'm about an hour out of Newcastle in NSW. Where are you at?

Cheers!

 

I'm about 20mins up the freeway north of Perth CBD
