i just currently bought a 2003 gt. it is my baby. i previously owned a 2001 v6 and added a few parts and made it a beast compared to my friends v6. im wanting to put a kenne bell 9 psi supercharger on it and i have an auto transmission. i was told it should hold the power. im also thinking about the accufab tb 75mm and k&n fipk cold air intake. eventually port and polish heads and bore block and maybe some cams. what gears should i use? what injectors? shorty or lt headers? can anyone give me some helpful advice?
