My car likes the 2 inch carb spacer, not sure about the scoop

It left with the front wheels about 3 feet off the ground and carried it out a ways after that things went south though. The engine was missing like it was either lean or way rich. I'm not sure if the scoop and no air cleaner is causing it to syphon gas out the carb vents or if it's just that lean now. It was fine during the burnout right up to 7200, and like I said it left hard.
