VICTOR E-TEC EFI (2500-8000 RPM) The 29145 is a Vortec/E-Tec version of our popular Victor E 23° EFI manifold and is intended for EFI applications like our Pro-Flo 3 EFI system. This manifold features a similar deep plenum and tapered cross-sections like the Victor E 23° and is compatible with standard, square-bore, throttle bodies. This manifold is one inch shorter than the existing Super Victor E-Tec EFI #29135. It also has provisions for water bypass so it can be used on Vortec engine blocks and accepts OEM alternator brackets. 45 psi Maximum Pressure Paper Element Steel Housing Material Hose Barb Attachment Sold Individually
