Propane question

93 Krawler · 12-16-2014, 05:03 PM

I am planning on running propane on my rig and was curious about the usage on a v8 engine. Need to know if I need a 2 tank setup or 1. How much do you guys running propane on v8's use? Any regrets switching to propane?

2 tanks period! or you will be pain in the ass needing sumone to run to tow rig and get another tank! I run the 10 gallon tanks and run 1 out in 5-6hrs perdy eazy if hammering on it

My 22re was a pita with just 1 tank. You really never have much of a clue how much is in them.

A friend with a 460 in a fullsize typically runs out one tank and goes to the second in a day, assuming the first is full to start out with. He carries three so he can start out on a partial tank but still has two full ones.

He really likes propane but was also coming from a carb. Obviously the propane doesn't hiccup on hills like the carb and has a little better throttle response, but don't know anybody that went from fuel injection to propane.

The downsides are he lost a little bit of upper end power on the moderately built 460 (350 HP, 500 FT-LBs) because the single mixer simply isn't big enough, but it's not bad. The other is the convenience of getting fuel. Not like you can just pull into the closest gas station on Sunday afternoon down in BFE Kentucky and top off the tanks. When going on a 2 day trailride out of state my friend makes sure the three tanks on the rig are full and carries three more in the tow rig. Probably overkill though.

Thanks for the input.

I know it sounds kinda dumb to go to propane from EFI, but I can't get it to run right. After I put a new cam in "nothing drastic" it runs rich. Edelbrock swears this cam will run fine with the stock EFI. I've replaced all the sensors, distributer, entire throttle bodies, and it still runs rich and bogs down under a load. I don't think the new cam is working well with the EFI. I don't want to pay the money to try and tune the OBD1 system. So I either swap in a newer engine "5.3" , or keep what I have and go propane. I already have the intake and a HEI distributer for the pane. I would like the extra power from the 5.3, but what a pita to swap it in. I really like the simplicity of the propane. I'll run through the EFI one more time to make sure I didn't miss something.
