'76 Dart Lite -- Budget Boost Build

The good thing is the inside is NOT welded. This will allow me to tack the portion closest to the intake tube, then pie cut and bring down the diameter that is right under the carb. The tubing is 2.5 inches, the carb is 1.5 on the butterfly / venturi. I will trim some and squeeze it down, then weld a flange that will allow the carb to bolt to the transition. I still have 3/4 of the do-nut, so I can do this again down the road, if I need to move up to a 2 barrel. Since it is unwelded, I can open one end, and add some material in the middle, if needed.
