The Holley GM LS3/L92
Modular Hi-Ram Intake Manifold
is introduced as a cost
effective alternative to
fabricated sheet-metal for
high-performance applications
where induction system height
is not limited. Coupling this
Hi-Ram intake with the high
flowing LS3/L92 style cylinder
heads has outstanding
potential for N/A and forced
induction applications at a
budget-minded cost.
Aggressive, bold, race-bred
styling will make bad
intentions clear for drag
race, muscle car, marine,
off-road, sandrails, pulling
trucks, track, street-rod
applications and
more!
- The base is
designed to be modular in
configuration to accept a wide
range of carburetted and EFI
tops and to be attractive to
builders and fabricators as
the foundation for custom
induction
systems.
- Runner length
and the tapered cross-section
designed to perform well for a
wide range of engine
configurations
- Cast
aluminum
construction.
- Intended
for use on N/A or forced
induction engines in the 6.0
to 7.0+ liter range, max power
at 7000-8000+RPM.
