Be sure that all brake lines and fuel lines are clear of headers and/or connector pipes.
All spark plug wires, battery cables, or other electrical components should be clear of headers
and/or connector pipes.
Make sure the dipstick and dipstick tube have been installed properly.
Double-check the tightness of all bolts including brackets and accessories.
Perform these checks again after the first 1000 miles.
START THE ENGINE
Start the engine and allow it to warm up to operating temperature.
Caution! Hot parts! Wear protective clothing as needed.
Check for any unusual noises or exhaust leaks. If every thing is OK, stop the engine and

NOTE: Check the bolts periodically to make sure they have not loosened. Re-tighten after the
first 500 miles and then again at 1000 miles.
