New SHORTBLOCK. Break-in advice???

[robs97snake]

Well I plan on changing the oil Monday, and that is going to be right at 500 miles. I have been creeping into the 5k+ rpm zone a couple times but plan on changing oil before going all out.

if the car has already been ran and heat cycled multiple times the "run it like you stole it" break in argument is null. with each new motor i've ran i've always ran it long enough to check for leaks or other issues then reamed the hell out of them!

Just try not to drive in reverse much, or it'll take even longer to get those 1,000 miles.

nice,

Ive seen engines that werent anymore than a few hours off being assembled make their way to kennedale and run some 4.70's, they drove that car around the pits for about 10 mins after firing it for the first time, then made a pass... I personally wouldnt run it more than a few hundred miles with out changing the oil and that would be broke in for me....

The engine in my race car has never had an easy day in its life. Almost every time it starts it sees RPM north of 7k with a lot of WOT. In fact, I think the easiest time it had was when I first put the engine in a car and started it to check for leaks, it ran 30 seconds or so, it was shut down and taken to a dyno, and that happened in 2006, hasn't been freshened up since. Food for thought.

Edit: I've replaced the valve springs in it once, and I did the intake gaskets at the end of last season, it will get a freshen after the end of the year.

x3. was told by my engine builder to drive it at about 2k for a few minutes, then 3k, then hammer it, then take it home, and change the oil. he said that is all the break in that is needed.

THAT's an engine builder!

I'm happy that the insurance covered the $5,800 repair and I only had the $500 deductible

There have been tons of research done in this area and he has a valid ?. Unfortunatly almost all of the ring seat happens in the first heat cycle an engine goes trough. After that it doesn't matter. I alway run a fresh motor long enough to make sure there are no leaks and then I take it out and leave it in first gear, hammer on it and let off an let then engine compression brake it self this really puts load on the rings and seats them in. Do this three or four times, let it cool and change the oil. After that its fair game.

Why would it matter what we say? You already have your mind made up.

yup

[46Tbird]

Another question....should I wait until I get the first oil change to remove all the ring and cylinder bits or go crazy now and THEN get my oil changed?????

then you should follow your builders advice so you dont break it again and be out of pocket

Nope. New aluminum block but they polished my heads when they machined them.
