Need Proper Break-in Procedure for new APE Motor I'm getting conflicting ideas . . . old school says to break it in fairly easy for 500 miles . . . new school says idle it for 20 minutes, change out the oil, and go beat on it.
What do you say?

okey dockey 
If you are going to tune it run it on the dyno and different RPMs and let the rings seat. Your going to be at WOT after that. She'll be broken by then.
If you put install it and break it in on the street for 500+ miles I believe you run a greater risk of washing down the rings and hurting the motor if it's rich or even worse. At least on a dyno you can control the proceedure much better.
I can hardly wait to hear how it all works out for you Dug

OK . . . so the car is at my house now . . . it will obviously be fired up from there. The dyno is a half-hour drive from my place. My tuner has suggested that after the initial 20 minutes and oil change, that we just hit the streets and start tuning right there, at least to get the A/F down to a reasonable level. Would that protect it from washing down until I strap it on the dyno?
I'm getting excited too . . . my limitation however will be the 42lb injectors. I'm hesitant to run the alky injection on the new setup, so I'm trying to sell both to get 60lb Mototrons.

Chris told me to fire mine up and let it run....... he said within 10 min the rings will have seated......... He told me to get 100 miles on it before i put a little boost on it... and i put 700 miles and a oil change befor eit hit the track.....
370ci right Dug???

Pm me.... ill answer all the questions you asked me before...........

100 miles before he puts boost to it? How will he break in that Camaro race car then? 
I would make sure you have a halfway decent tune on the fuel/injectors and then do the 10 minute thing. Rings don't need 500 miles to seat.

Can someone explain why the old school thought of 500 mile break-in with no more than 3000 rpm does not apply here? What makes the LS1 different from any other engine? Why is it that we can beat on this almost right away and you can't in any other situation?

Doug,
Pull the fuel pump fuse and unplug the coil pack's. Crank the engine over till you get some oil pressure. Plug back in the coils and fuel fuse. Fire engine, let it warm up to open the t-stat, top off anti freeze. Shut car off, check all fluids, start car up and go for ride. When first starting car try not rev it up to much, just get it to idle. For the first 100 miles or so just vary your driving, no constant rpm. After that go have fun. Also make sure that your tune is good.....you don't want to flood your engine with excess fuel. Take it to the dyno and tune it. Call me if you need any help.
Thanks

Doug,
BTW, old school thinking generally had to do with flat tappet cams. They needed a good break in before you abused them. Also older technology for rings took longer for them to break in.
Prostock, my Camaro will be a little shy of the 100 mile before boost break in by about 99 3/4 miles.

you shouldn't be worried about it being rich, if you still have the 347 tune the car should be a bit on the lean side and cylinder washout shouldn't be an issue. and you won't be hurting it by running lean since you won't be into boost and the pcm will compensate accordingly.
