Suggestions needed for a carb and convertor

EM is Engine Masters, which means they have to perform on a dyno for "X" number of pulls and are totally optimized to run at peak performance on them. Kind of like the old qualifying motors Cup cars used to be allowed to have. They'd last about 10 laps at WOT but made more power. EM engines, especially the higher placing ones, can sometimes be rough to actually put in a car and drive without some changes. Great contest, great engines, but they are no compromise to street or longevity in many cases.
