Chevy Mark V Big Block Engine Build Up - Power-Packed Mark V

As with any engine build up, it is important to know the exact timing of the engine's camshaft. For our purposes, Shewbert set the camshaft at a 4-degree advance.

The timing chain cover from Competition Specialties was a nice final touch. One way to tell the Mark V from the Mark VI engine is that the Mark V has 10 timing chain cover bolts-the Mark VI, only six.

Our initial installation of the Milodon pan was a learning experience. The pan rails interfered with the 4.250-inch stroked rods at the main rail-every one of them. We located the right Milodon part to avoid this. Make certain you ask the right questions when ordering your parts, especially if your engine has over 4.000-inch stroke.

This Fel-Pro head gasket features a special O-ring that ensures proper sealing. They work great with the RHS Pro Action heads.

The RHS Pro Action aluminum cylinder heads were installed dry over the Fel-Pro gaskets, and ARP 12-point head bolts were used to apply the squeeze.

For this application, Shewbert used COMP Cams lash caps. White grease was used to fully lubricate the caps both on top and bottom.

COMP Cams Pro Magnum Rockers were used with this high-horsepower and torque engine. They work great on the street, as well as on the racetrack.

Although hydraulic roller lifters work great on a street application such as this, Shewbert preferred the mechanical version for this high-lift application. These new COMP Cams Endure-X roller lifters are extremely versatile.

Shewbert selected the Dart single-plane intake manifold for the 540-cid engine for its great high-horsepower capability.

A staple with many engine builders today, this Demon 850-cfm carburetor proved a worthy component for this dual-purpose application.

Shewbert prefers MSD ignition products for this engine, including the MSD billet distributor and MDS 6AL ignition box.
