I have a 400 sb chevy that just been rebuilt and i was wondering the correct break in procedure before i can boost this engine.
the engine has 8.5 compression,J&E pistons afr 210 heads,totalseal stainless steel rings,the old fast fuel injection,oliver billet rods,callies crankand twin 67mm turbos.

I'm of the newer school of thought that the engine is broke in by the time you drive it. If the rings don't seat after getting on it a time or two (don't beat the **** out of it, but do pull it through the band) Then they are not going to.
Old school is x rpm for so long, another for so long, then drive it easy for 5 billion miles... blah blah.
I start mine, let them idle (adjust the valves if you have to), go through a heat cycle or two while sitting still. Makes sure everything is hooked up, plenty of coolant etc.
-Change the oil
Go drive it like you normally would.
-Change the oil (now put your normal stuff in if you run something expensive)
done
Mine saw boost with something like 10 miles on it, and only waited that long because I had just switched to a standalone, new turbo kit, and a new motor all at once.

Lol... "Then drive it easy for 5 billiion miles.."
That's too funny.
Your method does seem to be the rule nowadays. Thanks for the post.

MY last rebuild before boost was redlined on the first trip outa the garage and has asked for more ever since. This whole "break in" crap is for the birds.... do you think the guys that race 24hr races that just had to replace there engine the night before take it easy the first couple laps?! NO they beat the hell out of it! if its going to break its going to break, no amount of babying it going to make it better.....
