I have a 98 GTP S/C. I wanted to work on an engine but driving car to wotk monday thru friday. I bought a 2000 monte carlo for the engine and tranny. for just in case. I have a book you buy at autozone for specs and torques and etc. read on there that the engine is like no other 3.8 L. 3800 Series II. That the supercharger is only an added power booster but that everything else is the same is this true.
