SPECIAL NOTE:
This intake manifold is primarily intended for use with Vortec-style heads on pre-Vortec blocks. Standard engine blocks
route the thermostat bypass water from the block directly to the water pump through the passenger side water pump mounting flange. If the
manifold is used on a 1996 or later Vortec engine that does not have the in-block bypass passage, you must route a thermostat bypass hose
from the water bypass port on the top of the intake manifold water crossover to the 5/8” hose nipple on the passenger side of the Vortec
water pump. Use the 90° elbow, 3/8” NPT (pipe thread) to 5/8” hose nipple fitting, and 5/8” hose to accomplish this. If your engine block
has the thermostat bypass passage, you may plug the bypass port on the intake manifold.

PREP AND TUNING FOR POWER:
1.
Specific applications may show an increase in power by tuning the fuel mixture.
2.
Aftermarket distributor curve kits may be used with this intake manifold. HEI distributors WILL NOT fit.
3.
Use modified or high performance cylinder heads such as our E-Tec 170.
4.
Installation of aftermarket headers, camshafts or both may lean carburetor calibration. Should this condition occur, recalibrate with a
richer jet.
•
CAMSHAFT AND HEADERS:
Three-Deuce intake manifolds are compatible with aftermarket camshafts and headers. Header primary tube
diameter should be 1-5/8” to 1-3/4" depending on the specific engine combination. Edelbrock has developed two camshafts for use with
this intake manifold - Performer-Plus #2103 or Torker-Plus #5002. Please check the catalog or website for rpm and application guidelines.
INSTALLATION INSTRUCTIONS
1)
Use only recommended intake gaskets set when installing this intake manifold.
2)
Fully clean the cylinder head intake flanges and the engine block end seal surfaces.
3)
Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets,
allow to air dry, and attach the intake gaskets.
4)
Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼" high bead across each block end seal
surface, overlapping the intake gasket at the four corners. This method will eliminate end seal slippage.
5)
Apply removable thread lock, such as blue Loctite, to the intake bolt threads. Install the intake manifold bolts. Carefully
tighten the intake manifold bolts evenly until the intake manifold has lightly compressed the gasket.
6)
Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 11 ft/lbs.
7)
Install the oil fill tube by placing it into the machined provision. Place a block of wood on the top of the tube then use a
mallet to drive the tube in, until the 1.25” step of the tube is fully seated.
