[QUOTE="Morgan@Midwest Diesel & Auto, post: 1077876, member: 8143"] We did a 12v head here that flows right at 300cfm at 600ish lift..... 200 cfm is no better than a 6.4 head and it is feeding a lot less cubes.. remember on a turbo limited, fuel only class, feeding big displacement is not an advantage... Been proven time and time again in 2.6 that big displacement cummins and stroker duramax's do not make hardly anymore power than their smaller displacement original versions. Without larger turbos and more air, your just wasting efficiency and money. A big bore de-stroked 7.3 with 300 cfm heads @ about 6.0-6.5 liters displacement would be an animal. But then your right back at just using a 6.4 to begin with being cheaper and easier. The whole "no-replacement for displacement" is a foolish thing to say when your running a turbo. Especially in an inducer limited fuel only class. It's all about efficiency of the engine for the size/flow of the turbo your allowed to run. [/QUOTE]
