I just bought an Edelbrock 1403 carb for my 289. I have a 4bbl manifold I am going to modify. It appears I can grind the manifold to match the carb. Do I need to remove the material between the primaries and secondaries? Or should I leave it in. (I have pictures of a modified manifold with that material removed, and wondered why it was done and is it necessary?)
Input appreciated!!!
