That sounds pretty sweet,I dont know about the octane of 130 though. I'm going to try it on a '89 350 this time and see how far I can push it. I'm going to do every thing the same as last time, except im going to add two propane bottle's, and take it too a dyno and tune it. Supposedly more propane can be used than gas for a richer mixture without sacrificing power.I hope to get this project wrapped up by the end of next month.Safe nitrous
