my new car has a gmgoodwrench crate in it. where can i find out which motor it is, and specs on the motor???

 

Look on the passenger side of the block right above the starter, you should have a plate/tag attached, it should have the numbers you need to reference what motor package you have, with that you then can get the service parts list for that motor. I have a lot of info on all the GM performance Parts, I may be able to help once you get the numbers.
