So it turns out that my 1990 350SDL is burning a lot of oil and piston noise, after tearing the engine down it turns out I have a very slightly bent rods in cylinder 1 and 2 and damaged cylinder walls. I know I can get a 603.96X engine but I really do like the 350 engine... so much so I've already got all new internals coming in, the block will get new cylinder liners and is at the machine shop right now. the head is getting machined and rebuilt and the crankshaft is getting some work done as well.

Once the engine is all assembled and ready to be started, what is the break-in procedure for this engine?

Cheers
