"RPM AIR-GAP® INTAKE MANIFOLD
FOR 1992-97 CHEVROLET LT1 AND LT4 V8
Utilizing the proven short-runner tunnel-ram design for 1992-97 LT1 and 1996 LT4 engines, these
manifolds incorporate a .250" longer-than-stock runner and our patented Air-Gap™ design that delivers a
cooler, denser air stream for maximum power from 1500 to 6500 rpm. The throttle bore inlets are cast
larger than stock to accommodate our 52mm throttle body #3809 or our 58mm throttle body #3810. The
LT1 version, #7107, is designed for use on factory LT1 heads or Edelbrock LT1 heads #61909. #7109 for
the LT4 is machined with a .250" taller port designed for use on factory LT4 heads, Edelbrock LT1 heads
#61909 and the new Edelbrock LT4 heads #61939.
