in my van i ran the motor on cheap woolworths oil for 1000k. done an oil change and ran the motor on medium brand 30 grade oil. white driving around i let the motor work alittle when going up hills and not so much in high revs when gearing down coming down a hill.

Depends how much use it had? If its like a brand new motor, you want high quality non-synthetic oil for break-in. Run the motor for ten mins or so, varying revs up and down, but not idling, to break in the cam. Hopefully the assembly lube is still in place if the motor has just been sitting. When you start driving, avoid revs, but dont baby it, you could glaze the bores. Hills are good, load but not high revs.

If it was run for a bit, hopefully the cam was bedded, and with some good oil, you can pretty much just drive, without high revs and not babying the thing.

My motor had a 10 minute run under load on a dyno to bed the cam in, then I was told go hard and push it to the floor continuously in all gears for the next 500 ks but dont rev it over 6000. Then the oil was changed and no limits.

Yeh, Castellan, Ill go along with that.
With engine parts and oil quality the way it is these days, theres no need to go putting around running engines in.

I recommend only running for a very shory time, 1/2 hr to an hour, drain the oil and change the filter. This will hopefully get rid of any crap that was in the engine while getting built, (lint, dust etc) also if moly lube is used on a new cam it can block oil filters.
Then run a running in oil. I use Penrite, probably others around. Drive the car like normal or harder. Load it up in higher gears to make the rings bed in. Change to whatever oil you plan on running after about 500Ks.

Yrs ago when I was fulltime mechanicing, I used to fire them up in the workshop, warm them up, check for leaks, noises, etc. Drive out of town about 10ks, stop, check everything again, then drive back to town, flat in top gear. Never had a failure or an engine back.
