The other problem I have is I am making somewhere in the 450 HP range at 6,000 rpm from the old 350 with the intake, heads, cam, headers, etc. I have not been able to find a set of gaseous injectors large enough to fuel the engine alone and I am afraid to piggy back something. However I have seen some conversions for higher HP engines that actually retain the gasoline system and start bringing in the gasoline injectors when the gaseous fuel injectors start to max out. However with this system it crossed my mind that the "gasoline" injectors could actually be a secondary set of gaseous injectors. I did enough research about the subject to find out I need hours more research to develop a system to work for my intended purpose.
I am with you on the Ethanol. At $8.00 a gallon for gasoline distilling your own ethanol would make sense.
I do know that if I go dedicated gaseous fuel, the engine is coming out, getting flattop pistons and the head is getting angle milled substantially. I will be increasing the static compression ratio to the 11.5-12:1 range. I have also considered a 383 to keep the power output up.
