This kit allows you to switch back and forth between gasoline and propane from the driver's seat. They install in a couple of hours and don't interfere with the stock vacuum/ emissions systems. The purpose of this kit is to be able to drive on either fuel of choice without running out of fuel. This kit is excellent for daily drivers that want the benefits of propane while still bieng able to drive several hours to and from your destinations. As long as it's a standard 5 1/8 inch air filter mount (all holley 2 and 4 barrell, qjet, edelbrock, etc...) it's a direct bolt on. This kit is easily adapted to other engines as well. It is fully tuneable and the performance is much better than I had originally expected. We installed one on a 454 chevy and it flat out romps:smokin:

For the record, this is the kit that Ian featured on Extreme 4x4. We have had these out for about a year and a half to two years now and the customer feedback, as well as my own personal experiences, have been excellent! Several people have commented that it runs better on propane than gasoline. The kit is stupid easy to put on and tune. Feel free to ask any questions you may have about this.

This is the answer to not worrying about fuel capacity in a daily driver/ driven on the street to the trail vehicle.

How much for a kit shipped to 76053? What is the HP rating? It will be goin on a 258 at first, then on a mildly built 454 when I get around to putting it in.

The complete kit costs $895 and shipping w/insurance is usually between $37 and $50. I have several customers running these on stock to mild big blocks with excellent feedback.
