Im looking for advise on installing/using Ramair Manifolds with 2 1/2 outlet for my engine rebuild. I purchased a 63 convertible Catalina with a Stock 389 4 barrel and upgrading engine to 068 Cam Kit, forged aluminum Pistons and Tri-power Carburetors built by Mike Wasson from Pontiactripower.com . Mike recommended to reach out to Paul Dellfield's Son since Paul's passing. Pauls son mentioned he has Ram Air long branch manifold but cannot guarantee I wont have any issues with clearance. Has anyone out there used the long branch Ram Air manifolds on a 63 Catalina ? If so, what did you use and or where did you get them ?
Any recommendations would be greatly appreciate it.
