So many different opinions on engine break-in, but this one I believe in, although I would have let it cool down 100%, warmed back up and then raped.

Either they seat or they dont. Jeff's advice is the best just dont go rippin to 9k on it. Change the oil at 250 if your ---- 500 for normal people and you should be good to go. Self control is the key

That Motoman article was actually really good. The way he said to seat the rings is the same way we used to seat em on the vintage road course cars at my old job, and it actually does work better. Tops of the pistons were usually grayish/white, but there was never any brown color on the piston sides to indicate blow-by.

Re:Replaced piston rings, do I need to break it in?
everyone has a different way...
like someone said, decelerating with the motor coming down is a good way.
just really its hard to go wrong...
one thing NOT to do is add prolong or anyother no-smoke/engine restorers. they will not seat completely with taht ---- in there.
even if the ---- was in their before they might not seat very well. the prolong sticks to everything and you can hone the cylinders but once the oil gets around on its path it'll pick up more prolong.

Re:Replaced piston rings, do I need to break it in?
i read like 908934875 post from the net before i break mine in. and i decide to go with what the bke guys said.
i let it warmed up, then take it right out, and do the acc/dcc thing. and i think i did hit redline(ops :P)
rans fine until now, but now think i have a lot of blow by cause i`ve ran it NA for too long

Re:Replaced piston rings, do I need to break it in?
break in and hone is gonna determine how long it lasts not how hard it runs, guys that build track only cars dont even worry about break in, run a few hard pulls on the dyno, throw it in the car, do a few burnouts and check for leaks and its ready to go but those motors depending on how well it was put together and is tuned will at best last 1-2 seasons
if i wanted a motor to last as long as possible, id do a stock hone, run the suggested oil and change at suggested time periods for the suggested amount of miles and just make sure to keep the rpms low starting out and slowly start to raise the rpms the more miles that it sees until its considered to be "broken in"

Re:Replaced piston rings, do I need to break it in?
We kinda got tired of rebuilding engines every 500 miles. That's why we started taking the time to do things normally, instead of the slap together and let er rip deal. Besides, you can only listen to the boss bitch so many times about the cost of rebuilding a motor every month :P Plus those old vintage guys really don't really beat on their machines that badly.
