I know several people over here on C-3 have 200-4R transmissions in their cars. I am getting ready to fab up the throttle linkage for the Hilborn 8-stack EFI manifold for my project C-2. I need to add in a lnkage for the 200-4R TV system. To know what I need to fab I need an acurate measurement of the cable travel from idle to full throtle. Can someone who has the 200-4R setup running get me a measurement of the exposed cable length at idle, and at full throttle, so I can fab a cable holder and the correct travel linkage bar.

Thanks - Greg

 

Greg, try emailing Page62 he just put a TH200-4r in his 79, and should be able to tell you what you need. A few weeks back at a car show he and I had a long discussion on setting up the TV cable. His email is page_62@yahoo.com

Sorry about the delay. My engine was quite warm last night due to a great (low RPM/high speed) run in the Texas Hill Country!

The answer to your question: 1.25 inches (double-checked).

PS: This is without a doubt the BEST mod anyone can make to a C3 or earlier. There is nothing better than running 90 mph @ 2500 rpm! If I could take everyone on the forum for a ride, each and every one of you would be a believer...especially because I can demonstate 3rd (before -- 1:!) and 4th (after). Now if only I could figure out a way to get Bowtie Overdrives to give me a commission...

 

page62 , smokehouse69 - Thanks. I've been awa from the board over the weekend. That's just what I needed.

So can a 200-4r be made to hold 500 ft lbs?

I Imagine if it will hold up in Project No Flight, it will take what I can give it :lol:

 

I have a Level 2 BTO transmission. When I bought it I thought I was getting a beefier street tranny -- something that could handle a ZZ4. Turns out this thing is a shift-kitted monster! Shifts are like NOW! And downshifts are right where I want them, too. My wife asked me if all that "clunking" was normal. Yup, I said, explaining how the tranny was built for performance applications.

I think they can build these beasties up to Level 4!

 

427V8 - I've talked to several people who have said they wouldn't warrenty a trans over 450 ft-lb, 500 HP etc ... and a couple who said they can make one handle 600 ft-lb and 800 HP.

-Greg

 

Well I've just aquired a free 700-R4 so I think I will be going that route!
Just needs a little rebuild... :smash:

 

Yeah, but what all do you need and how much did it cost you to go through BowTies? I'm putting one in this winter. Nothing will stop me, it will happen. I hate turning 3200rpm at 70mph, no cruises in the country when I can watch the gas guage drop.

 

About $1600 including freight. If you're saying with a stock engine, you can save $150 and get a Level 1 unit; if you're going to upgrade to a ZZ4, go to Level 2.

No matter how you decide to acquire a tranny, do yourself a favor and buy a TV Made EZ kit from them -- it ain't cheap at 95 bucks, but I learned the hard way it's worth every penny.

Wait until you're cruising down the freeway at 85-90 mph with the tach needle staying below 2500 rpm! SWEEET... :yesnod:

 

I have a spreadsheet (excel) that calculates engine RPM for different rear end ratios, tire sizes etc.

Email me if you want it...

Basically with a 3.70 rear you drop from 3200 rpm to 2200 rpm:eek:

 

Hey 427V8, there's another thread going about TransGo shift kits. If you're gonna build that 700r4, you may want to get one of those (and NOT a B&M kit). You can buy 'em at http://www.bulkparts.com

 

$1600 is all? I might have to do this! I don't plan on staying with the stock motor, I plan on having about 425-450hp before I'm satisfied. Upgrade to a ZZ4? Isn't that a downgrade? :D (I like building my own...) I plan on getting that TV Made EZ, the old man only knows manuals inside and out, so we'll be figuring out this autos together! I'm not too worried about cruising RPM.... I just really want to see that speedo get to 140mph! Tops out at 125 right now.... Think I can get to 140mph with that OD gear?

 

Yes, you will go as fast as the engine (and your nerves) will let you.
Yes, $1600 is all for a Level 2 200-4R with all the goodies (no crossmember, yoke, or driveshaft mods needed for pre-81 C3's).

Go to the BTO website (www.700r4.com) and send an inquiry. You'll get a looooong, detail response!

This is a universal post that i have posted in several forums and e-mailed to several trans companys.
-------------------------------------------
Ok, i have a 76 vette and am thinking of changing from a 350 turbo to a 2004r. The vette has a 3.08 gear and is pushing 300 hp soon to be 350 hp. the car is a daily driver and rarely ever sees a burnout or off the line racing,,,,,i like high speed. other than a stall and a shifter conversion kit, what other items will i need for this change.... also since this car is not driven hard, will a basic rebuild be ok, instead of spending the big bucks on a high performance rebuild.......

next question(s),,
now my rpm @ 65-70 mph is 3000,,,,if i get the 2004r that will lower my rpm down to around 1500-2000(i think) while i cruise in OD,,which will create excessive trans heat if i go with a 2500 stall, correct? On the other hand i would still like to have some get and go when i need it,,,hense the 2500 stall, so can i still use a 2500 or would i have to go with the 2000? This is a highway car 30 miles to and from my office 28 of it being interstate.
thanks


also with a 3.08 and 255/60/15's, wonder what a 5900 rpm in OD with the 200-4r, would push the vett in (mph)???hmmmmmmmmm

Just an FYI if anyone is looking at the 700-R4 instead. Art Carr has their extreme duty trans and converter package "on sale" at about $900 off normal costs. Alas, I wrote to ask if they would give me the same package on the 200-4R and it was a no-go.

-Greg

 

That's why I have 4.86 gears in the new 9" rear (but I've also got 29 1/2" tall tires in back :jester ).

-Greg

 

Hey Rat, with a 3.08 gear, Bowtie will likely recommend a 700-R4. This is for 2 reasons: the 700 has an extremely low first gear to help you launch faster. Also, the OD isn't quite as tall as the 200-4r, so the rpms won't be quite so absurdly low. Quite frankly, I have trouble at 55-65 on winding roads because I need to downshift to 3rd quite a bit (don't try this with a 700-r4, you'll kill it quick!)

Finally, you won't have an low rpm OD issues because the torque converter locks up in 4th -- no slip, no stall. And don't go with a non-lockup "dummy" converter -- that negates the whole point of having one of these trannies in the first place!

Anyhow, I think you'd be happier with a 3.55 or 3.70 if you go the 200-4r route!

 

I am actually planning on building a 700, my first, Yes it will have a 'shift kit' in it, big servos and all the super tough parts since I have over 500 ft lbs of tourque available.

Titinanium Rat: you will be turning 1780 rpm at 70 with a 3.08 rear and 255/60r15 tires. Thats a bit low...see the link below. They also say that you should run a lockup converter, at least with a 700, or you'll "wear the trans due to reduced lubrication." A 200 may be different

BTW there is a driveline place called Inland Empire that does U-joints and drive shafts. They say on their web site the running the engine with a lockup converter at less that 1800 rpm will most likely cause vibration problems, follow this link and click on the Overdrive Vibrations link http://www.iedls.com/guide.html

I just bought a 2004R off of e bay for only 200 bucks, the guy claims he rebuilt it and it was going into his turbo buick regal but he sold the car.
I figure for 200 bucks, I could either rebuilt it again if needed or just use it as a core. I will find out this week when I pick it up.
