I have about 950 miles on my engine now on it's second oil change.
Brad Penn 30 Wt. break in oil.

I figure it can't hurt to keep it there till at least 2,000 miles?
Any thoughts?

Okay we did the oil change with 20W-50 VR1 and Wix filter.  This is the first oil change and I did it at 600 miles.  Original oil was cheap stuff and we added zinc.

I have not had the pedal to the floor yet but would like to give her a good push and maybe hear the tires burn once or twice. 

Is it to early at 600 miles on a rebuilt motor?

Thanks.

Most folks would say to wait until 2k miles but heck it's your motor!!!

  By now the bearings are as broken in as they can be.  So are the rings, the only question is the cam.  If you are running a roller you should be A-ok. A flat tappet I would give another 500 before romping on it too much.

Drive it like you stole it. Every engine I ever built was driven balls to the walls from the minute the cam was broken in. Never had a minutes worth of trouble. Never understood the "baby it" theory? If assembled correctly, why does 50, 100, or 1000, miles make a difference?
