Product Details

The Manley 11719-8 is a high-performance Race Master intake valve designed specifically for Big Block Chevy (BBC) racing applications. This oversized valve features a 1.880-inch head diameter with a +.100-inch extended stem length, providing precise valve geometry for modified cylinder heads and custom valve train configurations.

Key Features:

  • 1.880-inch valve head diameter for improved airflow
  • +.100-inch extended stem length for deck clearance and rocker geometry optimization
  • Race Master series construction with premium materials for high-RPM durability
  • Precision-manufactured to tight tolerances for consistent performance
  • Designed for Big Block Chevy racing engines
  • Single valve (sold individually)

Manley Race Master valves are engineered for serious racing applications where reliability and performance are critical. The extended stem length allows builders to compensate for deck height modifications and achieve proper valve train geometry in competition engines.

Great

Ordered a set of 5 steel wheels, distributor messed up and only sent me 4. 5th wheel is taking a good couple weeks to arrive due to the distributor messing up the shipment. Autoplicity did make things right and I can honestly say now I would recommend them.

- Updated review -<br>Autoplicity.com contacted me after my original review and admitted to making a mistake with my order. They have refunded my shipping and I am happy now.<br><br>- Original review -<br>After 18 days the part finally arrived. The filter appears to have been sent directly from K&N, but I ordered on the 20th of June, yet the packing date that K&N Engineering Inc. shows is July 3rd.

Very pleased with Autoplicity's fast and efficient service. The part I ordered fit and looked great. Will definitely consider Autoplicity for future orders. Thanks.
