The tunnel ram with two carbs will put drive, out run and generally out perform ANY single 4 intake every time. Anyone who claims otherwise is doing something wrong. Your best money will be spent on carbs from a custom builder. In no particular order is Thumpr carbs (Dom) Lighting Carbs (Mark Whitener) and Baldwin Performance (William). Any one of those three will hook you up. Then you’ll wonder why you weren’t running a TR on the street years ago.
