Btw with back to back (expensive) pulls my chevy V8 went form 355ish hp on propane to 366+ but .5 degree cam advance. Prior we tried 2-3 degree creep ups and builder thought that was it and he won our bet on my weird combo not making more power than the propane carb rated to feed. Built as pure torque monster never need more than upper 4000 or tires roll off rims and aero dynamics taking flight. Have dyno in a semi trailer set up which was ventalated ok but more like operating a steam locomotive with all the pipes and valves and big clock face guages and extra loud being that close enclosed.
