Running in an engine

I'm hoping to get the audi back on the road within the next few weeks and will be running in the engine after rebuilding it. I'm going to try and get hold of some Millers running in oil, but failing that I'm going to just put some 10/40 mineral oil in and use that. Never done this before so its all new territory for me, anyone done this? I will be changing the oil after the first 200 miles and then again at 500 miles then at 1000 miles i will go back to my usual fully synthetic oil.

Any comments or suggestions welcome

dont drive it ANY different. Just do a lot of oil changes whilst running it in. Start it as you intend to drive it! if you fanny about with it the rings will NEVER cut in everything will carbon up and you might as well have not wasted your time. Most engine builders ive spoke to and any tuners say give it death! Big hills, high gear, full throttle. Really load the engine up hard.

Yeah similar to what I've been reading up about, will probably load it up aswell put a few tractor weights in the boot, not too many hills about nearby so guess having to lug a bit of weight around will help giving it some load. Don't really want to venture too far away from home in it just yet

I built a kr headed 6a costing the thick end of £4k, on first start up I let it get warm then gave it death.
Giving it a hard time shouldn't be a problem but letting it warm up in its own time as opposed to kicking it's head in from cold is a good habit to have.
As soon as the temp gauge moves over the 2nd marker = GAME ON !!

Change the oil often, 500 miles for the first 2k then every 2k from then.
A magnetic sump bung is always a good purchase. money well spent imo.

That engine sounds interesting Guy what was the specs of it?

And yeah i always let an engine warm up before giving it any welly. Good idea on the magnetic sump bung, i need a new one anyway as its currently got the vr's old one in it. I swapped them when i changed the vr oil last year as it was half worn away by speed bumps, the audi's one was like new and that was showing no signs of moving anywhere at the time so i nabbed it
