Product description

Fits for AMC and JEEP 1970-1991 304 360 390 401 5.0L 5.9L 6.6L 6.4L V8 Engine

Product Features:


	
intake manifolds are low-rise, dual-plane designs with patented runner tuning and a 180 degree firing order that you won't find with the competition. This combination boosts torque over a wide rpm range, from idle to 5,500 rpm. These manifolds also deliver improved throttle response over stock intakes and are available in both EGR and non-EGR style.
	
Notes:Will not accept Motorcraft spread bore carburetor. Will not work with '69 and earlier cylinder heads. Two center bolt holes offset. Do not use competition style intake gaskets for this street manifold. A factory metal valley tray gasket along with a composite/paper style gasket.

Please kindly refer to the below Important Installation Notes:

1. Alignment Issue: Intake Doesn't Seat Fully

Q: My new intake doesn't seat fully, and the bolt holes seem slightly misaligned. Why?

A: This may occur if your engine heads or block have been milled, resulting in a narrower valley. The intake manifold may require machining to compensate for this variance and ensure proper alignment.

2. Bolt Replacement Requirement

Q: Do I need new intake manifold bolts when switching to a JGhyperX aluminum intake? A: Yes. Since aluminum manifolds typically have thicker mounting flanges, stock bolts may be too short. Always use bolts of appropriate length to achieve a proper seal.

3. Surface Damage & Seal Integrity

Q: Will the intake still seal if the mounting surface is scratched?

A: For minor imperfections, composite gaskets can often conform under compression. However, severe damage may compromise the seal. We recommend inspecting and resurfacing the manifold if deep scratches are present.

4. Torque Specifications & Sequence

Q: What torque specification and sequence should I use?

A: Correct torque values and tightening sequences are provided in the included instructions. Strictly follow these guidelines to ensure a reliable seal.

5. Hood Clearance Consideration

Q: Will the JGhyperX intake fit under my factory hood?

A: Unfortunately due to the unlimited amount of variables that exist with each custom build or upgrade, you will need to check your available hood clearance for your application if this is a concern.

6. Carburetor Spacer Selection

Q: Should I use an open-center or four-hole carburetor spacer?

A: - Open spacers increase plenum volume. - 4-hole spacers enhance low-RPM torque and throttle response. - Wood fiber laminate spacers help reduce heat transfer.

7. End Seal Recommendations

Q: How should I seal the front and rear of the intake to the block?

A: For applications that traditionally use end seals, apply a ¼" continuous bead of RTV silicone, ensuring it overlaps the corners of the intake gaskets.
