It is mandatory that you pre-lube all engines prior to start-up. Failure to properly pre-lube can lead to bearing failure. The oil pump must be spun long enough (with a drill motor and oil pump drive shaft) to insure that oil has entered all oil passages and can be seen coming up all of the pushrods in the rocker arm area. THIS IS EXTREMELY IMPORTANT.
To break in your engine after assembly, use a 30W, non-detergent, non-synthetic oil for the first 500 miles of street driving, and then change the oil and filter. We recommend that superchargers be disconnected during the break-in period. Assembling a high performance engine should not be attempted by anyone unfamiliar with the common engine building techniques. If you are unfamiliar with any of the above mentioned terms or specifications, please consult a professional engine builder.
Before you turn the key and head for dray strip or open road, your new crate engine needs to be broken in.
