brake parts had to be donated to a friend, or she'd be rolling.

open manifolds rule!

haha nice

[GPXSS]

was that a newly rebuilt engine, or just a top end swap?

[v6h.o.]

its a full on rebuild/hybrid swap. only chris is taking his sweet time getting it drivable... :P summers almost over chris! get it driving and to the track!

[Z2_4cams]

full rebuild, 3100 pistons,moly rings, .018" milled off the heads, yadda yadda yadda

Sounds good, especially for just having six cylinders. Looks like fun...can't wait to see action and dyno footage!

[GPXSS]

whoever cranked it certainly wasnt treating it like a newly rebuilt engine

[Z2_4cams]

pfft. it never went above 4500 rpm

[RidgeRunner]

But isn't the proper run-in for a new engine to run it at ~2000-2500 rpm constant speed for about 20min? To seat the lifters or something like that?

Yes. but he might have already done this?

Unless I had driven it for the 200 miles or so already, I wouldn't be revving it to 4500rpms.. probably wouldnt go much over 3500.

To each his own I guess, I've always just followed GM's recommended breakin procedures.

When I replaced *just* my cam, I did the constant 2k for 20 minutes and then never went over 3k until after I had driven it over 100 miles. Even then, I still barely got on it for almost 800 miles (had to go to the 60V6 meet in Ohio 2 days after the cam install).

I definately wouldn't be revving it very high either, there is no reason not to follow the break-in procedures. However, my dad bought his '02 GTP Brand new and it had like 60 miles on it when he got it. So he drove it home (another 15 miles) and put a CAI and 3.4" pulley on it right then. Then he beat the piss out of it. He said thats the "proper" way to break in a car. But, it runs pretty good now with 25k on it so it must not have been TOO bad on it. However, I would bet GM does their own type of break in on the engine before even letting it out of the plant, so thats kind of different.

I didn't think roller cams needed to be "broken in". The only thing to worry about should be seating the rings. But I agree, if it was my engine, I wouldn't be revving it to 4500 right after the first start up.
