I have a pair of good Weber 44 IDF carbs but thinking they may be too small for the 2.7l Type4 being rebuilt. Anyone have some coaching on carb sizing?
Edit - maybe up to a 2256? Thanks! |

I ran dual 44s on a 2056 and they were necked down as far as I could get them and they were still too big. All my power was from 4k-6K rpm. For a 2270 44s would be about perfect.
That said - Get fuel injection. Zach |

Similar experience here. I ran 44's on a modified 2.0L with headers. The carbs were too big and powerband was similar to what is mentioned above. |
