Component Information:
350 RJ Intake Manifold:
This kit comes with a Chevrolet Performance Parts port fuel injection intake manifold designed especially for the RamJet
350 engine. This cast aluminum intake manifold comes with two holes in the rear of the plenum. The hole in the rear face
of the plenum is tapped for a 3/8" NPT fitting and should be used for a vacuum port to operate the brake booster. It is in
close proximity to the distributor so it may be beneficial to install this fitting after the engine oil is primed and the distributor
is installed. The second hole is in the right side of the plenum and is tapped for 1/4" NPT. This hole is used for the vacuum
port that supplies vacuum to the fuel pressure regulator. The fuel pressure regulator is mounted on the left rear fuel rail
and uses a male -6 AN nipple on the bottom. This is the fuel return line that will be necessary to adapt to your application.
The right fuel rail has a 3/8" NPT hole that is used for the fuel inlet. You will need to determine what will be needed to
adapt the inlet fitting to your application.
Note: If your are installing this package in a vehicle that was originally equipped with a carburetor or TBI system, the fuel
lines will need to be upgraded. The fuel lines must be able to handle the increased pressure required by the fuel injection
system. Do not use any barbed fittings or worm clamps to secure the pressurized fuel lines in your fuel system. Also,
ensure rubber lines are replaced with flexible hose of sufficient strength (i.e. stainless overbraid and AN style fittings for
example). Finally, use caution in routing fuel lines to ensure that the lines are not located too close to the exhaust system
and are protected from road debris or obstructions.
Water Pump:
The RAMJET 350 engine includes a standard rotation water pump. This is a cast iron, long leg water pump.
Any small block engine, regardless of year, that uses Vortec heads, will require an external coolant bypass line from the
intake manifold to the 5/8" hose nipple on the water pump (passenger's side). Suggested routing is from the 3/8 NPSF
boss on intake manifold to the water pump.
Ignition System:
This kit includes a distributor ignition system that is connected to the ECM. The ECM monitors the inputs from various
engine sensors, computes the desired spark timing, and signals the Ignition Control module in the distributor to adjust
timing.
The spark plugs recommended for the RAMJET 350 engine are AC Delco part number MR43LTS
