Hi Im from Ma. I've been a GM tech for 12 years now. I just bought a 2004 GTP with 300K! The car was a company vehicle and all highway miles and is in very nice shape. Original motor and trans, I was surprised the motor still pulls strong but first thing im going to do is dissassemble the motor and transmission and overhaul everything. Im sure the componets are beat inside both. My plans are to modify both engine and trans while im in there and hopefully put up some good numbers. Im sure I can find all the info I need for modifications here and if I can help at all on the GM side just let me know.
