The Holley GM LS7 Modular
HiâRam Intake Manifold is
introduced as a cost effective
alternative to fabricated
sheetâmetal for
highâperformance
applications where induction
system height is not limited.
Coupling this HiâRam intake
with the high flowing LS7
style cylinder heads has
outstanding potential for N/A
and forced induction
applications at a
budgetâminded cost.
Aggressive, bold, raceâbred
styling will make bad
intentions clear for drag
race, muscle car, marine,
offâroad, sandrails, pulling
trucks, track, streetârod
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
crossâsection designed to
perform well for a wide range
of engine
configurations
- EFI
fuel rails are machined for
â8AN Oâring Fittings with
passages large enough to
accommodate high fuel flows
and dampen pressure pulsations
in the fuel system and come
standard with EFI HiâRam
kits.
- Cast aluminium
construction.
- Intended
for use on N/A or forced
induction engines in the 6.0
to 7.0+ liter range, max power
at
7000â8000+RPM.
