I just picked up this truck, it has a 350 with a propane conversion kit. My old 350 chevy had some gnarly balls and I've heard you lose a little bit of power when running propane instead but I also have a 3.0L ranger and its got more power then this and its a V6. So I was wondering what im supposed to check on these propane engine, no previous exp. With them, and how I can or could get some more power out of it. Thanks Aaron.

You shouldn't lose that much power. The only thing you can check is the propane system itself.

Check your lock-off fuel filter.
