if it is GM stuff you put on your car, it does not delete your warranty (as long as it is installed by an official GM dealership; make sure to keep all papers and documents)
use non-GM-stuff you can easily have a problem
take a look at this forum or/and some others, and you will find cases, where cars had all kinds of engine probs (worst cases: engine died!)
you would never be able to proof that your non-GM-aftermarket part was not the part causing the prob, i.e. your problem will NOT be covered by warranty...
so: if you can afford buying a new engine just for fun, there is no prob going non-GM...
if you consider killing your warranty a waste of money...
