I have just completed 1000 miles running in period and had the oil/filter changed on my car which had an entire new short block put in. I asked the dealer as to how I should now progress :

1. Can I rag it now ?
2. Do I now need to keep it below 3500rpm?
3. Or what?

No definitive answer given.....any suggestions greatly appreciated as I wish to keep this engine for a while.

slightly rag it for the next 1000 and then go for it IMO.
Just make sure you let the oil get warm before you do.

LOL.......Thanks, what sort of rpm do you suggest? I have no idea about any of this and am petrified of damaging the engine. So far since the oil change I have not gone above 3000rpm. Can I give it more wellie?

A common approach is to build up peak revs slowly. Say limit it to 4500rpm, then after a few hundred miles, go to 5000, and so on. If you've warmed it through, and it's done 1000 miles, IMHO you'd be OK with occassional quick visits to higher revs (say 6000) in a lower gear, just don't leave it floored in top for ages! When my car was 1000 miles old, I tended to just use enough to keep the turbo spinning in all gears when I wanted to go - change up at ~4500rpm, still plenty of performance, not really stressing the engine.

hades has put into words what I tried to!
