Remember, at the track the OD will never engage. So do your 1/4 mile gearing calculations with the first 3 gears only.

Probably the best modification I have made to my 65 GTO was to put a 200/4R trans in it. 400 with 3.73 gears (13.20’s @ 106 in quarter). I got the trans for free from a friend but junkyards have a lot of these transmissions. The newer the trans. the better. http://www.bulkparts.com/ is where I picked up the rebuild kit converter. I think I had $450 in the rebuild kit, converter, and shift kit from Summit. Rebuilt it myself. Second gear is a little soft under full throttle but I just need to install a larger servo for like $120. I would recommend getting one of these from a junkyard and taking it to a local shop if you don’t want to do it yourself (Hays makes a book on rebuilding transmissions). Bolts in TH400 x-member location, TH350 yolk, and the same driveshaft. The larger the boost valve in the pump the better. My shift kit came with a .500” unit. I can’t think of the brand off the top of my head but it came from Summit and was like $110. Speedometer gears were like 40-60 bucks! I used the same from a Monte SS.
Hays Manual 13 vane pump kit Hardened stator shaft support Second gear servo Shift kit Rebuild kit Fluid and filter New trans mount 350 yolk (junkyard or someone always has one) TV cable TV cable bracket OK I’ll stop rambling not. Who ever thought pinewood derby cars would lead to this!

Not rambling at all RA462, I appreciate the info! I have the Hayes manual as well, and after reading it, came to the conclusion that Its best left to a profesional. Theres a ton of parts in one I can just see me making that one small error that causes much grief. I think that Ill go with a 3.55 and 200R4. Maybe someone will be willing to trade for the 4.11 setup.

Or maybe a 3.73... Btw, I hear the hardest part of the swap is usually getting the TV cable adjusted?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
