Our Level 2 installation kit provides all the little, often over-looked items plus many critical components you'll need to install your new replacement engine. Now is the perfect time to replace those old gaskets, plugs, wires and thermostat, etc. You wouldn't want an old water pump to jeopardize your new engine or have an old starter leave you stranded after all the work yo've done. All parts are new items direct from our Chevrolet Dealership! (Please make note of your water pump length in the "additional comments" area during checkout.)

For a more complete setup, we also offer this engine with a nearly turn-key Level 3 Install Kit.

This engine is new from the oil pan to the valve covers, including the four-bolt main engine block. The nodular iron crankshaft features enlarged journal fillets for increased durability. The camshaft is patterned after the famed 327cid/300hp profile from the 1960s; coupled with the larger displacement, provides good low-end torque and plenty of passing power. Cylinder heads are 76cc cast-iron with 1.94 in. intake and 1.50 in. exhaust valves.
