    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!!

    1. I believe the "Lube Scoop" is different for each size sprocket.

    From the transtar catalog:
    702B Scoop, Chain Scavenging (2nd Design) (For 33T Sprocket)................................... 1 91-Up 84702B 24201870
    702B Scoop, Chain Scavenging (2nd Design) (For 35T Sprocket)................................... 1 91-Up 84702C 24201869

    2. The catalog only shows ONE option for a 4T65e chain.

    From the Transtar catalog:
    700F Chain (4T60E) (Round Pin 7/8’ Wide)............................................. ......................... 1 91-93 84700A 8660099
    700F Chain (4T60E) (Exc Round Pins) (Replaces Rocker Joint Pins & D Pins) .............. 1 93-99 14700B 24202447
    700F Chain (4T65E) (w/ Mouse Ear Link & D Pins) (.500” Wide) (Dual Chains).............. 1 97-Up 84700G 24206434 ← This is the ONE 4T65e option

    3. No personal experience, but Ive seen others say a dual chain is better than the 7/8" chain overall.
