If I order the 300 I have to buy and additional 140? dollar part. And for that he said you might as well go for a 450.

I will try to get under the hood on Sunday.

The IMPCO 200 mixer is rated at 345cfm and is plenty for the 2f engine. I can get up to 70mph in my FJ40 with 37" bias ply iroks. I can also out accelerate Mark's stock 78 FJ40 off the line. I do have a HEI distributor and have the timing advanced to 16* at idle.

Air Flow Capacity…………………………….……345 cfm @ 2.0 in Hg manifold (derate 15% for methane)

Take a look at the online pdf catalog and it will tell you everything you need to know about the IMPCO mixers that are available. http://www.impco.ws/download/Web-Catalog.pdf

Honestly the best route to take is the Jeep kit from Propane Conversion Kits and find a holley 2 barrel adapter and the mixer will bolt straight on.

[GAS-A-LOT!]

LT YOUR KILLING ME
Where were you last week? I would have stuck with a 200. Oh well, I got this set up now... I will start the instal after July 6. Now, I will have to start getting the additional parts together. Like an electric fuel pump plus a spare. Any one know the flow requirements? Also, Do them heat wraps for the manifolds work in keeping lower temps under the hood?

LoL, was wondering if someone would list gotpropanes site. I've only heard positives about him and his kits. Everyone says they are the most complete.

Amazing. That Impco gear looks like the same stuff I was selling back in the 80's.
What I would like to know is: Can I buy a 500 gallon tank for propane (like I might have at my cabin) and have some kind of re-filling pump that I could use to pump it into my LC?
Also, whoever figures out the optimum way to convert a 62--obviously injected engine-let me know the details.

When my original propane set up was stolen I called up Cary and Got Propane to see what his jeep kit was like. Come to find out that the base plate he was using was the 2 barrel holley style so everything bolted right in place of my old set up.

The holley 1 barrel base plate that Cary uses is offered through IMPCO. Look under the 425 mixer spec sheet and you will see the different base plates that they use. Instead of using a 4 barrel holley base plate you can use the big 1 barrel and use two different adapters to run the 425 mixer.

Only if you are switching to full time propane. Running dual fuel you cannot just use the holley base plate unless you are running a holley carb at the same time.

The 425 will not hurt your performance. A stock 2F will function just fine with a 425.

The nice thing about propane mixers, they are a demand thing. They are not as picky as a carb is for over fueling.

Cary has been listed a couple of times in this thread. He is a good dude..

Propane systems have not changed much at all in the last 20 or so years. There have been advnacements, but since there is not really a huge need for anything more than just a basic system things are pretty much the same. There are some really neat computer controlled systems out there now tho.

Any el cheapo fuel pump will provide enough gasoline for a 2F. Any NAPA should have a suitable fuel pump for under $50.00.

[dp777usa]

You asked for my source on the recommendation that you run gasoline through the engine every few fill-ups. That comes from my travels in Argentina where about 50 % of the cars run on GNC gas naturale compressado. That is how they do it down there on dual fuel systems. It may depend on the vehicle you have. It use to be that the valves and valve seats used in American engines didn't hold up as well with gas. Also there is the issue of the gasoline carburation system drying out when gasoline does not run through it.

[hammered]

How goes the install Gas a lot???
I am guessing you have it in by now.

I am off in the morning to buy a full kit.
the seller says it will work on my 2F.
If it works out I will post also.

I am going the donut on the top of the carb like Peru has on his.
No Impco here avalible.


Checked into the HH2 kits but smells like snake oil.
Have yet to hear of a real person making it work.

So the Propane is on for this week.

Great thread.
I am sure others will be into soon as the price is nuts worldwide.
I will be paying about a $1.50 per ltr here this week.
Over 5 bucks a gallon and it is low octane junk no one else wants.

[kitb]

lpg is the shit,this is the best thread that this forum has to offer right now,who cares about sliders when gas is going past five? I have talked to a scientist kinda guy,(cool) and he was saying that the HHO kits should work on lpg even better than gas because of the amount of hydratoms starting and ending in the mixtures,lets find out, Powderhound? got anything on this?

[bumfj60]

Awesome thread! I should have everything I need by Friday.

[hammered]

Kitb keep us posted on this Hydrogen thing.
I have been reading up on it for a month and yet to believe it really produces.

I did read that for this set up you would want to use Lpg pieces for the mix.

Would be cool if this really does work.
Not sure about the combo of Hydrogen and propane fuels.
Kindda like making your own Mapp gas.

I would love to hear the "science" behind this...

Dude, I would get a friend to bring you down the Impco gear. It is the kind. I have heard about the donut rig. Not impressed.

[hammered]

I now lots of people running the donut ring .
Not idea myself if it preforms well.
The cars seem to run though.
Hell Peru on this thread is running the same one I plan on installing.

I will know this week one installed.
I have owned lots of propane 350s and 454s in the past up in Canada.
If it sucks I will have my sis send me an impco.
She is 3 blocks from the propane guy BC CND.

Propane likes high compression and the timing has to be advanced. Engines made to run on propane don't lose any power but you should expect a power loss on a stock engine. This is especially true if you set up a a dual gas/propane system because you can not advance the timing enough for the propane and it is too far advanced for the gas. They do sell setups that advance the timing when you switch but it is expensive and I am not sure that you will save any money in the long run. You would have to drive it for 10 years on propane just to get your investment back. Also new propane parts by Impco or anyone else tend to be pricey. Mainly because you have to have a tank, cutoff, regulator, and mixer, not to mention the hoses $$. On a good note propane burn very cleanly and in most case extents the life of the engine. I still suggest you change your oil but when running propane it won't look like it needs to be change. Another neat thing is that your vehicle will run the same at any angle. There is no stumbling when you get sideways on a hill.....

Or even upside down actually

[kitb]

mine took about six months to pay off, where do you get 10 years?

[wengejor]

if you look on page 3 you will see that the break even would be around 12,000 miles of driving with today's gas prices...maybe he only drives 1200 miles/year...thus the 10years required!!

[hammered]

I have been following this tread for some time now.
It's great!
Hope to be hooked pu this week with LPG on my 40

Been drinking lots of beer tonight. Serious.
Not sure if I should publish this as I proof read it.

Going to let the cat outta the bag for the ones that can't afford the big investment.
Go to craigs list in Canada and search Propane LPG or Natural gas.( parts) Try Vancouver 1st
You can find a system for 300 bucks + or -
I am not saying this is the way to go.
It is like rolling the dice.
Buying online it rolling is a gamble.
it may not be complete or just dried out junk but then again you may luck out????

Here on Mud it is a tight group and kindda policed between the group, but I am telling the guys on a tight budget you MIGHT find a deal this route.

My 1st and only propane rig was a 1 ton flat bed with a 454. 20 years ago.
We bought it at a gov auction for a steal.
Back then Propane was 5-7 cent a liter.
It ran like crap up the hills. NO guts but would get there.
Mind you we had 3 tons of gear on this welding rig & we were always drunk and never tuned the damb thing cause it started and got us to the job site.

We also had a transfer hose.
No one has talked about this yet.
I barely recall what it looked like due to the fact this was 20 years ago and I was hammered most of the time.hahahhhahhha
We always had a BBQ tank as the jerry can and if we ran out we get this filled and hook up the hose and juice up the tank.
Might be a good topic to the experianced. Like I said I was hammered and wandering around with a BBQ tank back then.

Anyhow What I am getting at is there are some used systems avalible in the North.

Canada has been on this system for well over 20 years.
The Gov gave kick backs for converting at one time.
Parts and pieces all over the place there.

Might be a good source for parts for those interested.
You might be able to find the tank, mixer or carb you need or hell maybe even a system.
As I said roll the dice and take your chances.

[hammered]

Just thought of something.

The jerry can BBQ tank and tranfer hose is illegal. In Canada anyhow or so I was told once.
You have to have taining to fill these tanks.
It isn't like pouring reg gas into your tank.
You can howerever do it if you can find a someone to make a transfer hose for you.
This bailed me out on a few occations with the big block welding rig.
No guage for fuel gauge ine the cabin.

Maybe someone more qualiied can give the steps of refilling your main with a BBQ jerry can setup.

Propane Guy sold Transfer hosed up till a year ago and then I never saw them on the site again.
He might be able to make one up on request though.

[red_dirt_okie]

I pulled 10 years out of my ###. I don't drive my cruiser much but I do drive more then 1200 miles a year. I was being goofy as I posted a reply after reading only the first page. I didn't realize this thread was a novel with diagrams, charts and so on. You guys have covered almost everything. Ignore me.

RDO

[Mace]

transfer hoses are easy to make.

I have one.

A couple of the comp guys have set up the little lantern bbq bottles for small fuel cells as well. Gets about 15 mins worth of driving..

[kitb]

no problem R D O, I just assume that we all daily drive them I guess. just cuz i do!

[hammered]

Mace could you post a shot of the transfer hose and steps for topping up the the tank using this system.

I plan on using this set up lots.
Every corner store has full BBQ bottles for exchange here.
Main cooking fuel for the whole country here in Costa Rica.

In my case it will be really handy to run in grab 2 bottles and fill up rather than drive across town to a LPG station.

[Mace]

Here is a good writeup on it.

The only thing specific is that you need to have the proper ends for your tanks..

propane

[ntsqd]

One thing that I've noticed not mentioned directly is the hoses used. Both Propane and Nat Gas can permeate normal rubber gasol
