I am working on a 292.The thread is"Help needed to change 4 piles into 1". We did a demo at Bonneville and put one on my 270 GMC for a few minutes. That thread is "Bonneville.... TBI conversion - installation demo". It is really pretty simple,well not simple but easy. When done I'll only have about $600 in it including the laptop to tune it! Here are links to forums by guys who run MS systems.
