Product Details

Fits:

  • 1967-1991 Jeeps with 343, 360, 390 or 401 Engines

Description:

This Edelbrock Cylinder Head is designed as a bolt-on performance upgrade for any 1967-1991 Jeep with a 343, 360, 390 or 401 AMC V8 engine.

They include adjustable rocker studs and guide plates set-up for use with small-block Ford style adjustable 1.6:1 ratio rockers. The intake flange is dual-drilled to accommodate early and late model intake bolt patterns, covering 1967-1991. Complete heads include larger than stock valve springs to handle most high lift cams. They feature stock location ports for compatibility with standard manifolds and headers. A direct bolt-on for 1970 and later engines with 1/2" head bolts, these heads include step-dowel pins for pre-1970 engines. Their dual-quench combustion chambers produce approximately 9.5:1 compression in 401 V8 engines. The 45 intake seat angle offers improved mid- to high-lift flow over the stock 30 angle.
