Engine Break-In Procedure
Use or break-in oil or conventional (non-synthetic) 10w30 oil with zinc additive for the first 500 miles of operation. Do not drive for long periods at any single speed, always vary your speed. Do not tow a trailer or put other heavy loads on the vehicle. It is best to avoid long periods of idling during this period. Check the engine oil and coolant levels daily.
At 500 Miles change the engine oil and filter using conventional (non-synthetic) oil with a zinc additive. Check fuel and ignition settings, adjust valves (where applicable). Drive the next 500 miles normally, without high RPM's (below 5000 RPM), hard use, or extended periods of high loading or long periods of idling.
Change the oil and oil filter again at 1,000 miles. Continue using conventional (non-synthetic) oils and zinc additive, until about 4,000 miles. At that point, you may run a quality 10w30 synthetic oil if you choose. The use of oil with zinc or a zinc additive for the life of your engine is recommended.

Specifications:
Given that this is based off a “magnum” block, would this be able to drop into a 1994-2001 Ram 1500? Could I swap in Hughes Fuel Rails on an Edlebrock EFI Air Gap intake and run on factory electronics? If not, what are my options for a crate engine here?
I have a 1972 Challenger Rallye, with the original 318 engine with only 60k,,,would like to find a small block replacement with good HP. also I would need to know what would be a compatible transmission and rear end.....any suggestions?
What size headers are recommended with this motor? Can you jet this motor for between 5000-7000 ft. (Colorado) Do you have an option for the black Mopar Magnum valve covers?
