Product Description

Holley EFI Fuel Rail Kit

for Holley 300-137 LS1 LS2 LS6 Intake Manifold

Holley is an industry leader when it comes to GM Gen III and IV LS engine performance parts. Their LS Single Plane Mid-Rise Intake Manifolds are now available for both carbureted and EFI applications. They are ideal for higher horsepower engines as well as those that are incorporating power adders such as forced induction or nitrous oxide.

Thanks to Holley's advanced casting technology, these intakes weigh in at only 11.5 lbs. The runner design of the intake manifold features a constant cross sectional area and is ideal for a broad power band from 2,500-7,000 RPM. They feature consistent wall thickness throughout for balanced performance and sealing strength. This excellent design also features the lowest carb mounting flange height possible without sacrificing any power.
