Engine Break-In Procedure

Use conventional or break-in oil (non-synthetic) for the first oil change, be sure to check the oil level in the engine and prime the oil system with an engine priming tool.

Engines with flat tappet hydraulic cams only - Run the engine between 2,000 and 2,500 RPMs, with no-load on the engine for the first 30 minutes. This is critical to breaking in the camshaft.

Drive the vehicle with varying speeds and loads on the engine for the first 30 miles. Be sure not to use a lot of throttle or high RPM. Run five or six medium-throttle accelerations to about 3000 RPM (40 to 50 MPH), then letting off in gear and coasting back down to 20 MPH. Run a couple of hard throttle accelerations up to about 5000 RPM (55 to 60 MPH), then letting off in gear and coasting back down to 20 MPH.

Let the engine cool and change the oil and filter using conventional (non-synthetic) oil and check the coolant level, top off if necessary. Drive the next 500 miles normally, without high RPMs (below 5000 RPM), hard use, or extended periods of high loading. Change the oil and oil filter again using conventional (non-synthetic) oil. Keep an eye on oil level during the first thousand or so miles.

It would be suitable to use synthetic motor oil after the second recommended oil change and mileage accumulation.

Forget the rebuild - the best crate engine value comes with classic chrome style!

The 350/290 Deluxe combines Chevrolet Performance's most popular crate engine with an aluminum intake manifold* and chrome dress-up kit to create one of the most stylish and value-driven engines on the market. The chrome dress-up parts include the valve covers (with push-in breathers and ''T-bar''-style hold-downs), timing cover, and air cleaner.

Like all of Chevrolet Performance crate engines, the 350/290 Deluxe starts with a brand-new block. And it's a strong one, with four-bolt mains. It also includes a smooth hydraulic camshaft and durable aluminum pistons that deliver an 8.0:1 compression ratio. It's a powerful, durable engine that makes a great alternative to rebuilding with your old two-bolt block.

Chevrolet Performance has all the parts you need to get your 350/290 engine running, too, from the starter and distributor to the plug wires and more. If you want even more power, our high-performance cylinder heads will take this stout Small-Block to the next level.
