200-4r questions for 1950

Thanks for the info Rippinron.
I've seen Bowties' site before.
Should be an alternative to the $100.00 + linkage setup.
TCI has a setup for about $100.00.
Anyone have any other alternatives?
Any help will be appreciated.

RippinRon You will need the appropriate linkage for the edelbrock carb as well. http://bowtieoverdrives.com/catalog/...php?ITEMID=213

200-4r questions for 1950 chevy

Thanks for the info 66 sedanman.
I've been to both sites before.
My reason for asking was that on another forum another fellow rodder said he reused his kickdown cable on the same switchover. I know on a 350, the kickdown cable is to drop it into second gear, for passing, and on the overdrives the TV cable regulates pressure.
I've got three local shops available to build me a transmission, just hoping someone had made a similar switch.
Any further help will be appreciated.

66sedanman Also they make a universal dipstick , and also sell the tv cable wich is the same for the 200-4r and 700r4 here:

COOL

I always have a 28.5 or larger tire and way more camshaft, so my RPMS would be too low with a combination of your rear and a 200R4 ... But yours looks about right

66sedanman Chevy Dan,
The 200-4r doesnt use a "kickdown cable" it uses a TV cable wich is very important to set up properly because it controls hydraulic pressure in the trans.

Heres a site thats has some good info and parts for the 200-4r:

200-4r questions for 1950 chevy

Thanks for the info Deuce.
Did the computation for my car. Being I'm running a 24" tall tire (P205-75R14),
I'll be doing 1,969 RPM at 65 MPH. I think that's where my small block should be at, (350, RV Cam, 600 Edelbrock, Headers, HEI), with the 200-4R.
Looked better at my RB'S transmount. I might be able to rotate it to the back, and modify somewhat to make it work.
Flywheel, shifter, dipstick tube?
Any help will be appreciated.

Deuce I, myself would not go to a 200R4 ... because the Overdrive in it is 33 per cent. With your rear end ratio of 3.23, the ratio in OD will be almost 2.10

With a final drive ratio of 2.10 ... Your RPMS could be very low and lugging the engine. MPG very well could be worse ... a 3.70 rear ratio would be way more acceptable.

200-4r questions for 1950 chevy

Thanks redlightning, looking forward to overdrive.
My brake master cylinder bolts to my K-member, reluctant to move that.
I understand my 350 flywheel will work, not sure. How about the 350 kickdown cable? Still looking for a proper mount setup for the tailshaft on the 200-4r. Any help will be appreciated.
03-09-2008 07:20 PM
redlightning I put a 200-r4 in an 80 camaro that had a th350 with the short tail shaft.I just moved the th350 cross member back and used a hole saw to drill four more holes in the subframe.(This is not a show car)
I have heard of people moving the tab on the other side also.
The driveshaft was fine.I reused the lines but did have to bend them.The car came with an aftermarket b&m shifter that I reused also.
It was really nice having the overdrive.

200-4r questions for 1950 Chevy

I have a 1950 Chevy Fleetline, with a 350 engine, and a 350 transmission with a 6 inch tailshaft. It has a 10 bolt 7.5 inch rearend with 3.23 gears.
I'm wanting to put in a 200-4 R transmission. I have the original K-member in the car, with an RB'S 350 Transmount. I want to know if anyone makes a
transmount for the 200-4R. ( I know the mount needs to go rearward), or if anyone has an idea on fabricating a mount.
Also is the flexplate an issue,cooling lines? I have a hurst Pro-Matic shifter in the car, could it be modified to work with the 200-4R? Any help will be appreciated.
