Edelbrock 4603

Edelbrock 4603 is a pair of Signature Series steel valve covers for Ford Small Block 260, 289, 302 and 351W V8 engines. The black textured covers use a tall profile, internal breather baffles and an embossed Edelbrock logo.

Application / fitment

The covers fit selected Ford Windsor cylinder heads using the traditional perimeter-bolt pattern. Confirm rocker clearance, intake-manifold height, accessory mounting and engine-bay space.
