Turn Key LS Engines
Golen Engine Service Turn Key LS engines are designed to drop in to your existing set-up with a minimum of hassle. All turn-key engines are fully broken in on our engine dyno which takes about a day and a half from start to finish. This includes running approximately 20 gallons of fuel through the engine, 2 oil changes and the filters are cut open and inspected. A leak down test is done to ensure the engine is sealed properly. A dyno sheet with full horsepower and torque graphs is generated and included with your engine shipment.

So even if you may already have a part or two that is included in the turn-key engine package, the added assurance that comes with a fully dynoed and broken in engine is well worth making the decision to go turn-key.
