new engine break in

I put a reman 351M my 79 bronco. I bought it on ebay from these people.
eBay Store - AA AA AUTOMOTIVE RARE NOS OEM PARTS: classic Mustang parts, Late model Mustang parts, Carburetors

What is the typical break in procedure ?

I finished putting the motor in at the begining of last year. I got the carb tuned but it didn't have any brakes. So most of last summer I spent replacing everything in the brake system. Finally I have the brakes working and can now drive the thing. SO before I really go driving it I thought I should finish breaking the motor in.

Hold it at 2000RPM for 20 minutes.

I generally change the oil after that 20 min break in, and then again after 200 miles.

You should prime the oiling system and be sure ther's oil pressure. This not only confirms oil pressure and flow, it pre-lubes the bearings for that initial fire-up.

Oilling system primers fit into the distributor opening and onto the oil pump shaft. When you spin the oil pump (the drill needs to be running in reverse), oil should flow from the rocker arms and there should be a healthy reading at the oil pressure gauge.
