M1 Single Plane Question

Hey 69Chrgr,
I had the same issue with my M1 intake and I replaced it with an Edelbrock Super Victor. My engine builder really showed me and explained to me that with the M1 I was not getting good fuel distribution at all and was losing HP. He was going to send out the intake to get it setup for a Holly DP but then we found the Super Victor and went with that.
