I don't know if it would work at all, but The thought occured to me. The fu's 5.0 is still complete as far as the efi goes. Now it's going propane. I was simply going to disable the gas end of things and put on the propane to start with. I have a a 5.7 that I want to rebuild later for propane, but for now, this will work. I'm wondering if I can run the propane as a fogger like they do in the desiels. So I can switch between them or run both. I've never seen anything on running both at the same time. Any thoughts?

you would have no prob running dual fuel I know a bunch of trucks that do.

is this an "after a bowl" question?
how are you going to add more air to match the extra fuel?

No bowl or other thought provoking additions, and yes, at the same time. I kinda like the twin turbo idea, but that won't be for a bit.

there is no point to running 2 different fuels simultainiously
there might be some benefit in a boosted application to spray liquid lpg to get a cooling effect but other then that you would have to compromise the timing and compression to suit a blend
diesel guys do it to stuff more fuel into the engine, there would have to be extra oxygen in the cylinders to burn with the lpg to add any power
I wouldnt waste my time with propane on a deisel engine, if you need more fuel then add more diesel fuel.

but dont some forklifts run gas and LPG at the same time?? If I where you I would pick gas or lpg and run one.

running propane with gas wont be like running propane on a diesel. When you build the 351 for propane make sure youre 11:1-12:1 compression, I cant remember if propane likes lift or duration better. Go to fuelsforum.rasoenterprises.com they have a really good propane forum.
