Propane BaBy!!!

race4fn · 09-06-2011, 03:46 PM

Looking for some advice on kits that are out there and available for a sbc, the motor is a stock 350 with vortec heads running an edelbrock performer intake, full lenght headers....maybe 300 hp or so..
I have been looking at the got propane kit thats good to 420 hp, any advice on this kit, how much tuning etc...

nashfuels is best place to buy, impco 425 mixer, model e convertor and a vacuum lockoff if u choose to run a lockoff

X2 on bill nash.... he can set u up w everything. Or like me, u can mix and match. I dident need the goofy chrome air cleaner or regulator mount, but I did want a splitter and fttgs for 2 tanks, and electric shutoff vs vacume.
If for some reason u do buy from him, be kind and tell him u know me(rob mickelson) as I'm running nash fuel flags werock '12 ..

Iam a complete newb to propane, what will I need besides the kit and a tank?
What about how much propane does it use compared to gasoline? I would use between 6 and 10 gallons of gas on a typical weekend.....

Propane use is almost equivalent. So in you use 6-10 gallon of gas, you'd probably use 7-11 gallon of propane. The common tanks (forklift) are 33lb and are roughly equivalent to 8 gallons. At a minimum, I would think about carrying 2 tanks on the vehicle and having 2 spares on the trailer.

thats not bad at all, what about tuning the propane system, is it anything like a carb? or is it just install and your ready to go?

For me it was 2 screws/adjustments. There is an idle mix and a main. For the main on offroad use, keep turning it richer till you get no more power then turn it back a fuzz. This method wasn't scientific, just seat of the pants and it worked for my micro 1.3l

Your reasons are the same I had for going propane. I built a f/I harness and had no probs, but I always wondered if I did have issues w the ecm, or if I melted a specialty plug, or if it just wouldent run right, I would be at harlan and not wheelin w my buddies..

To me, having to run two bulky tanks and maybe(?)loosing some power is well worth it, cause if my motor wont run right, or start ,I can diagnose it w a timing light, a dcv meter, and a corn dawg in my other hand. And that is a big selling point to me.

K.I.S.S. kinda try to follow that a lot, anything iam taking miles back into woods, rocks, mud, water, and trees;) i want as simple as easy as possible..my motor, trans, drive shafts and axles i can get parts from anywhere, if the propane craps out my trusty, but sucky 4160 is always in my tool box...lol

Had propane on the v6 in my last buggy and loved it. I had originally tried to set it up with FI but I'm cheap and wiring retarded so I went with lpg. Figured if I couldn't make it run at home in the garage there would be no way I could fix it in the woods. As for loss of power I can't say because I moved up from 4 to 6 cyls when I switched to propane.
