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 RPM's, with no-load on the engine for the first 30 minutes. This is critical to break 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 coolant level, top off if necessary. Drive the next 500 miles normally, without high RPM's (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.

Specifications:
Will this fit a 1967 corvette stingray 4 speed manual? Mine had the 427/435 tripower but is gone now. Have the original side exhaust still.
Will it fit in a 65 impala SS
Will this engine fit a 1965 Corvette? Currently a 327 cu. In. Understand that suspension components, cooling and driveline will require upgrade. I assume that the mentioned oil pan (and components) will require kit.
In one of the questions the buyer of this engine mentioned that he had to change out the oil pan because it was to deep. Would I have to change out the oil pan for it to drop into a 1970 chevelle/ It currently has a big block 396 with a 5 quart oil pan.
Will this Engine Replace or Fit a 454 EFI Chevy Engine on a 1997 P30 31 ft Lg Motorhome IF not do you have one of these Available in that Size Category a 454 7pt4L And do both Size Engines weigh the same too
Will this fit in a 72 Chevy C20?
Looks like it would be a perfect fit for a 1970 chevelle SS?
Will the zz427/480 fit my 1957 Chevy Belair. I've been told that the oil pan may hit and the valve covers will hit the fire wall. Any thoughts?
