What are your goals?

 

Welcome.....lot of hp plus propane makes 7.3 blocks crack....easy on the fumes you should be ok with hp and performance without going overboard.

 

sorry guys i was out of town for a family thing that came up unexpectedly...my goals are to be in the area of 6-700 hp with this truck. i already have the water/methenol kit, and dont get me wrong i love the power, but i am still looking for more. my buddy has a propane kit, and he loves it, and says he has a ton of power for towing as well. maybe i am going down the wrong avenue, but i think it may be the next step in the hp line other than injectors, or a new turbo setup.

 

If you are after that kind of power consider injectors instead of propane.

At best propane will get you an extra 80 hp and it will cost as much as injectors.

 

You are not going to get anywhere near that kind of power reliably without a purpose built engine. To have a 600 horse daily driver you'll need a prepped block, billet rods, low compression pistons, big big injectors and at least one big turbo....head studs, premium headgaskets, and main stud girdle...etc, etc.

No matter what avenue you decide on your stock turbo does not flow enough air to support your goals. My advice would be to get a bigger turbo and a set of stage II injectors, than add a 100HP shot of NOS. That will put you around 450 at rear wheels and still be mild enough to not need to get into the block.
