I plan to finalize my plan to build a double gassifier system for my 1975 Chevy Silverado 1/2 ton. It has a 350 cid w/2 barel carb, turbo 350 auto trans at this time. I do have another motor that will be built with four barrel carb, higher compression pistons and cam with more lift and duration. This will give me much more power and help with the higher octane rating of wood gas. Still working out the way I will equilize between the two gassifiers but that isn't going to be much problem. Just going to have to spend time tinkering that through.
