The LSX454R features a high-compression (13.1:1), solid-roller combination that uses new LSX DR 11-degree cylinder heads (part number 19166979). The heads represent the full-race LSX head from Chevrolet Performance and are designed for the high-rpm, full-throttle use of racing. Their cavernous, 316-cfm rectangular intake runners flow 430 cfm at 0.800-inch lift (with 28 inches of water restriction), providing even greater volume than the already-large LS7 intake ports. Large 2.25-inch intake valves and 1.625-inch exhaust valves contribute to their tremendous airflow.

The LSX DR heads boast the LSX family’s signature six-bolt-per-cylinder head bolt design, which provides exceptional clamping strength, and they are matched on the engine with an exclusive, all-new high-rise open-plenum intake manifold and a Holley 1,150-cfm Dominator carburetor. The intake is designed expressly for high-rpm, large-displacement racing engines and incorporates two rows of cast-in injector/nitrous bosses.

Additional specifications and features of the LSX454R include:

Mechanical roller camshaft with .738/.738-inch lift (intake and exhaust) and 250/270-degree duration (intake and exhaust)
Shaft-mounted, 1.9-ratio rocker arms with needle bearing fulcrums and tips
7,100-rpm maximum engine speed
58X ignition wheel
LSX eight-bolt crankshaft flange
Requires LSX ignition controller part number 19171130
Racing gas of at least 110 octane is recommended for the LSX454.
