Propane's not gay, its just misunderstood! I pieced mine together from junk and it works great!!! There can't be an easier fuel system to set up, a tank seems to last way longer than everyone told me they would, it runs at any angle, won't spill out if you roll over,and you can work on a running vehicle inside all day and it won't kill you. The only things I don't like about it are dragging 2 extra tanks around, and remembering to get them all filled before a trip.

If I had 2 identical engines next to eachother both with flowmaster mufflers, could you tell a difference in them by sound?

if your nose was plugged no but i will say driving it you will. when we put it on my buddies sammy (i know some of you have weedeater engines that have more power) it was like a fresh engine as far as the power was concerned. propane i think is like 110 octane and it sure made his feel alot more responsive

That's why forklifts and other stuff with engines that are inside a building all day (i.e. warehouse, etc...) run propane.

i built my set up the same way and it is amazing how simple it is.
your prob gona need a 200-250 mixer, a regulator(converts l.p. to vapor, and these all do the same thing), and a vacuum block off/filter first in line. look here https://www.altfuel.com/

Hahah, just reading this...

difference in sound, no
difference in smell, should be minimal (almost "no") if running right
110 octane... yes-ish
takes longer to burn, burns hotter I think (exhaust valves do not love propane)
BTU's per gallon about 90% of gasoline
You can usually make up for less energetic fuel through timing adjustments or propane specific cam...

Liquid draw tanks (BBQ is vapor draw tank) converted into vapor, delivered at any angle... It's cool stuff for sure...

The only exhaust should be CO2 (again, if running right), so yes/no on the "breath exhaust all day long" piece... CO2 is still an asphixiate.
(It will displace the oxygen that you need to live, well, that most need to live)


I have a 425 that needs rebuilt, bought it when I was going to go C3H8 but plans changed... couple of throttle plates too I believe... I gave all my tanks to CW...


btw, just for fun youtube "BLEVE" (pronounced 'BLEV-EE)
...Boiling Liquid Expanding Vapor Explosion

I love propane! Especially the fact that it doesn't spill out when I role over.

like I said... just for fun...

I happened to catch a show on explosions last night... had some of the biggest ones filmed... LP train car was sick... tossed sections of car thousands of feet...



Anyway... I don't know that I've seen/heard many folks say that it was the worst thing they have done...

Thanks for all the info folks, it has been a big help.
I will for sure be using propane when i get to the motor/trans/tcase swap in my truck. I have almost everything i need now, just missing hoses and some fittings and some small stuff. Now i wish i could just find time to work on the truck. Gonna try to be ready for a test ride in early spring.

Oh yea, the 'bleve' video was great, and i have seen the train car explosion
on TV.

thanks again
