Ok I wasn't sure where to place this since we do not have a racing forum here....

But anyway I just got my Cobalt SS...When will it be ok to run the 1/4 mile??? After 1500 miles?? At 1500 miles I plan on changing the oil and putting some of GM's Assembly Lubricant in the motor as well....Any input is appreciated!

 

as soon as you break it in, so 500 miles or so if you do it right

although, i wouldnt launch hard til later
