SBF 351W EFI Intake Manifold R-Series

Take the guesswork—along with meticulous work necessary for accurate port matching—out of dialing in your big cube engine build for huge power numbers with Trick Flow's R-Series 11R 227 port-matched carb-style EFI intake manifold. The A319 aluminum manifold's CNC Competition Ported runner treatment has been specially designed and machined with perfect port alignment on Twisted Wedge® 11R 227 cylinder heads. The high-flow, one-piece spider-type single plane design with raised plenum floor puts the powerband in the 3,500-7,500-plus RPM range. Custom-machined fuel injection nozzle ports accept standard Bosch and Siemens-type fuel injectors.
