Dude, I got triple 48mm Dellortos on me Charger, the key is not the carb, its havin a really good analogue vacuum gauge to balance them. I pull nearly 1200 cfm at full welly boot and it eats Skylines for lunch. Port match yer head to exhaust and inlet then bench flow it, then choose the carbs. You will have the ugliest but coolest Wagon in the world. Any Reconnditioner or head specialist can do this for not much, love the idea.
