ENGINE OIL: The engine is supplied with Edelbrock Break-In Oil in the crate. Before starting the engine, you will need to prime the oil system. Do not turn the engine over with starter motor for priming. Mark the distributor, as it comes preset on #1 cylinder. Then, remove and use a priming tool to turn the pump shaft.
Change the engine oil no more than 300 miles after break-in. Use of oil with zinc or a zinc additive for the life of your engine is recommended.
