    Keep it at 75-100hp or you will kill it. Even then use caution. Adding fuel and retarding timing is a good thing when on the bottle.

    i ran propane in my 5.0 305 once right into the throttle body, ran pretty awesome, dangerous though without a way of turining it on and off and with a regulator, spun them all the way to 3rd gear in auto....

    ah i mean...its dangerous period

    Joe D said it well.

    Most people that have issues over revving or running lean and the BANG.

    Some guys recommend add a second fuel pump and bigger pick up and fuel line that injects gas with the spray to help the lean issue.

    You may consider a forged pistons.

    Get a turbo instead, More expensive at first but alot cheaper in the long run. Check out the remote mounted ones, http://www.ststurbo.com/home. Extra 100 horses all the time without even seeing the turbo under the hood. There nice!!
