Trick Flow R-Series Intake Manifold for SBC w/ Holley 4150 Pattern

Trick Flow's R Series Intake Manifold is tailored around big cubic inch small block engines producing 600+ horsepower in the 3,500-7,500+ RPM range. Engineers at Trick Flow optimized the R Series intake for their Super 23 230cc cylinder heads, but found it also performs extremely well on Trick Flow's Super 23 215cc cylinder heads as well as other brand heads with 215cc and larger ports.

The secret to the manifold's success is its CAD-optimized plenum and runner design. Trick Flow engineers incorporated a one-piece single plane, spider type design with a raised floor and a large open plenum, paying special attention to smooth airflow for equalized air and fuel distribution. The design was optimized to eliminate excess material where possible, but enough was left around the port openings so the manifold can be port matched and/or fully ported. Casting it in A319 aluminum keeps the weight low, and integral bosses cast into each runner can be drilled and tapped to accept nozzles for nitrous applications.

To back up all the engineering and great features, Trick Flow dyno tested the R Series Intake Manifold to ensure it can propel you to the front of the pack!
