We have a 96 gp se with the damn 3.1 v6. apparently the head gasket was blown and took out the middle cam bearings and snapped the cam. also had a bent push rod. why only that stuff i dunno but what i want to know is why this particular year is so hard and expensive to rebuild or replace. what is the difference from this to any other gp engine. next question. what does it consist of to swap a 96 boniville 3.8 supercharged engine into this car. cuz its prolly going to get scraped or that engine cuz the 3.1 is too expensive for what it is. would appreciate any help on this. its 'her' car and shes driving my truck because of it. im still in shock that she snapped the cam!
