I'm putting an io-390 in an RV-7A. I am trying to avoid complications concerning the fitting of the snorkle, and clearance with the bottom of the cowl. I understand that the FM-150 pushes the snorkle forward about 7/16" because of the spacer required and therefore requires a little modification. It is my understanding that the Precision doesn't do this. Has anybody run an FM-150 in an RV-7 or 7A with an angle valve engine? (Apparently the physical dimensions are the same between the angle valve io-360 and io-390. My second question is: were there any clearance issues on the bottom of the RV-7 cowl because the fm-150 required different cable routing?
Thanks
