    With 31" tires, those 4.11's are like a 3.52, and the GV brings that down to 2.75 final drive. That's about the same as my 3.73 with 28" tires, 3.55 to 2.77. The GV is good to 1200 HP, and they can modify it to take 2000.

    Leave your trans and rear end alone and just add a 75 shot of nitrous on the engine, done.

    I haven't broke mine yet and you know how many passes I made on that 200 with a full blown 125 shot which makes the 350 put out 500 hp and about 500 ft lbs

    I had numbers over 400 for both on a rear wheel dyno back in 2007, with the 125 shot.

    Plus I have that very stiff suspension with the big sway bars and all the other crap to make the car handle like a modern car.

    I should have broke it a long time ago

    Feel like spending 500 bucks...put on a 150 shot of nitrous on that car it won't care about that 342 gear you got!

    I bet you can click off an 11.50 at Quaker I was running 13.85 there on the motor and went 12.39 on nitrous there this summer with a 75-80 shot.

    you should be able to do that 11.50 easily with a 150 shot, got nothing else to do this winter. buy all the extra jets too so you can go smaller like I did.

    yours will scream on it with that roller cam and that intake spin that baby to 6300 you got the bottom end

    cheaper than that trainee

    oh come on it wont blow up you got newer stuff than I do I hit the rev limiter at 6300 on mine when I first used it racing a Mustang with a charger, banged second and pulled a fender. didn't blow up either, that was 50 nitrous trips down the track ago, at least, and 12+ years ago

    Thats the thing Im leery about, someone to build a "strong" 2004R.
    Im sure Vince Janice could, but would he actually be the one building it, or one of his employees?
    Another thought I had was these transmissions were behind castrated tiny V8's, 140 to 180 HP Olds 307's and some Buick 4.1 V6's
    I imagine the discussion in Buick's R&D back in '87 " Ok, we built an awesome turbo V6, 245 hp, 355 ft.lb's of torque, were going to use a 3.42 gear, WTF we going to use for an overdrive trans?"
    "Well we have the 2004R, we can beef it up a bit, it should be ok"
    I've been watching Precision Transmission vids on You Tube, Pretty good stuff, Rich knows his stuff it seems.
    He commented about the T350 trans. second gear clutch is huge, but third gear is its weak spot.
    Seems its 6 of one and half dozen of another:rolleyes:
    The GV seems to be my best bet if and when:cool:

    To me for your car the only advantage to going gv, might be the very few times in life were 2ndod might benefit you. This happens in trucks towing more than cars.......especially since we don't have any big hills here in northern Ohio.

    The 2004 is just about the same case size as a 350 on the od......uses the same yoke. Uses a th400 cross member location, and can be built to more than handle the power even the average 350 can dish out easily. Even having one built and and new tq will be less than gv. And you can recoupe some money by selling your proven stuff off.

    Mark,

    If you do go with the OD trans, I can build you the exact same converter you have now, to fit the 200 trans.. Can do it with, or without the triple disc Kevlar lockup clutch. Figure $629 without the clutch, or $765 with it.

    Thanks Jim, good to know!
    Ughhhh, I gotta stop thinking about stuff:mad:
    I think I'll focus right now on engine power, my aluminum heads, and see what that nets me at the track, and go from there.
    Seems like the 2004R is the way to go, but I'll cross that bridge when I get there:D:D
