Speedway Motors 9300114 Details

Many rodders are looking to install Chevy’s powerful and efficient LS1 / LS6 Small Block V8 in their street rods, customs and classic trucks. These shorty headers can make those installations easier in a variety of applications, and help produce more power as well.

An oxygen sensor bung is included with these block hugger headers, but not installed, for those who want to keep the engine’s electronic fuel injection. \

Bolts, gaskets, reducer tubes (2.5") and O2 weld bungs included.

Application

1997 and newer Chevy Gen III small block LS1 / LS6
Note: To allow maximum clearance, these headers require the use of our 916-18016 motor mount adapters. They will not fit when using the OEM LS-Series motor mounts.
