Hello to all my W-body brothers. Thank you for helping to keep Pontiac ALIVE!! This is my first post! I'm in the process of ordering all the parts for my Performance 4t65e build and have 1 question. I pulled the 35/35 sprockets from a NA GP at local boneyard. Should I have pulled anything else along with the sprockets or is everything compatible in my stock trans to achieve a true 3.29 ratio? When ordering my Gemini chain from TEP, is it a different size one than the OEM 4t65e from my '03 GTP. Also, should I go single or dual chain? My goal is 350-375WHP. Ok, that was 3 questions. Thank you all in advance for a little more 4t65e knowledge!!
