ghaskett Posted September 13, 2018 Share Posted September 13, 2018 Russ, at Centerville, out in California has a adaptor set up for a 200R4 to a 364-401 or 425. His set up basically replaces the original bellhousing, which is milled off. Has anyone used this set up? Thanks. Link to comment Share on other sites More sharing options...
Beemon Posted September 13, 2018 Share Posted September 13, 2018 (edited) You're best checking out the HAMB for that one. Check modified for a 57 restomod. They used a 700R4 but it's the same concept. Edited September 19, 2018 by Beemon (see edit history) 2 Link to comment Share on other sites More sharing options...
NTX5467 Posted September 14, 2018 Share Posted September 14, 2018 Check out the Riviera Forum for information on swapping a THM200-4R into '60s Rivieras. I believe there are several threads on that from several years ago. NTX5467 1 Link to comment Share on other sites More sharing options...
s_hilmoe Posted September 14, 2018 Share Posted September 14, 2018 I'm in the process of using his bellhousings to mate a 4L60E to a 401. Link to comment Share on other sites More sharing options...
RivNut Posted September 15, 2018 Share Posted September 15, 2018 (edited) You need to use the later 460LE transmission with Russ`s bellhousing. Earlier ones and the 200-4R do not have the separate bellhousing. Bendsten's makes the adapters for the nailhead- as well as the Buick straight eight and many other engines. These adapters come with a torque plate and a hub. The hub bolts to the flex plate, the the torque plate bolts to the hub. The torque converter bolts to the torque plate. The adapter is designed for the Chevy bellhousing, NOT the BOP bellhousing. The 200-4R has a dual bolt pattern (Chevy and BOP) so it will work with the nailhead adapter. I'll post some pictures when I can get to my computer. Ed Edited September 15, 2018 by RivNut (see edit history) 2 Link to comment Share on other sites More sharing options...
RivNut Posted September 15, 2018 Share Posted September 15, 2018 (edited) Hub adapter in place on the back of the crank - not shown is the flex plate which would be between the crank and the hub adapter. You need the stock flex plate in place for the starter ring gear. Adapter bolted on to the bellhousing - this is an Eelco adapter. torque plate bolted to the hub adapter Torque converter bolted to the torque plate. Transmission in place in a 1965 Riviera cruciform frame Before getting into this too deeply, find out the differences between the Chevrolet converer and the BOP converter. There is a difference in the mounting pads. The mounting pads on the Chevy converter are on the original flex platen- which you do not use. The mounting tabs on the BOP converter are on the converter itself. Having the tabs on the converter makes it much simpler to bolt to the torque plate. The best 200-4R transmissions are from the Buick Grand National, followed by the Chevy SS Monte Carlo and the high performance Oldsmobile Cutlass. There are quite a number of shops which can modify the 200-4R to handle 800 - 1,000 lb. ft. of torque. Talk to one of them before buying a transmission. You might just want to buy one of theirs that's already modified. You will also need to read up on the use of a TVC or throttle valve cable system which is a cable that runs from your carburetor to the transmission. Without one in place, you'll burn up the transmission driving it 50 feet. The 700-R4 and the TH200-4R transmissions ARE NOT computer controlled as are the newer L460-E units (the kind that Russ Martin sells the bell housing for.) The 700-R4 has a .70 overdrive, where as the 200-4R has a .67 overdrive. The 200-4R is smaller physically than the 700R4 if you're concerned with space around the floor tunnel or if you have a cruciform frame to deal with. Hope this helps some.

psychostang Posted February 18, 2020 Share Posted February 18, 2020 Ed, I just came across this post. I just purchased a built 200R4, and i'm acquiring parts. Your pics don't show up, do you still have them? Link to comment Share on other sites More sharing options...
RivNut Posted February 18, 2020 Share Posted February 18, 2020 Those pictures can be found if you'll Google Dave Gee's 1965 Buick Riviera Facebook. For some reason, the text accompanying the pictures has disappeared but you can get the idea. Once you find the page, click on the photos link Link to comment Share on other sites More sharing options...
psychostang Posted February 19, 2020 Share Posted February 19, 2020 Thanks Ed. I found them. I ran across this guy last year. I've seen these pics. That Eelco adapter is no longer available. Link to comment Share on other sites More sharing options...

psychostang Posted February 24, 2020 Share Posted February 24, 2020 No worries, I'm going with Russ' bellhousing. I'm just waiting for him to get back to me about the mounting plate. He sold the last one he had a couple of weeks ago. The guy he gets them from, sold the last three that he was supposed to be saving for Russ. The customer is sending it back to Russ, so he can send it to his machinist. I'm hoping he can make more. Hopefully cheaper too! 🙂 Link to comment Share on other sites More sharing options...
RivNut Posted February 24, 2020 Share Posted February 24, 2020 I thought Russ' bellhousing would only work with a late 460LE, the kind with the two piece bellhousing/transmission. To mount a one piece 200-4R, you need a plate, not a bellhousing. Bendstends has the plates. Link to comment Share on other sites More sharing options...
psychostang Posted February 25, 2020 Share Posted February 25, 2020 He has 2 options for the 200R4. One is the adapter plate system, the other is an actual bellhousing which mounts to the a plate, which bolts to the pump housing. This is after you cut off the original bell housing. It requires a specific torque converter from hughes, which costs $540. I was able to purchasae an already built 200R4 for $450. I'm just getting all of the pieces together.

RivNut Posted February 26, 2020 Share Posted February 26, 2020 Does the converter from Hughes have the lock-up feature. I feel that is as important as the overdrive. Link to comment Share on other sites More sharing options...
psychostang Posted February 26, 2020 Share Posted February 26, 2020 Yes. The part number for the converter is a Hughes number. It's based on their 9" converter which is made a little longer, and stalled at 2k rpm. Link to comment Share on other sites More sharing options...
cooterbfd Posted April 14, 2020 Share Posted April 14, 2020 Interesting Thread......I was discussing this with my son the other day about the transmissions. My question would be how do you get the 4L60 or 80E to shift? Thanks, John Link to comment Share on other sites More sharing options...
GS66 Posted January 20, 2023 Share Posted January 20, 2023 (edited) Does anyone have the printed instructions that come with Russ’s 200-4R adapter kit? I need a set. My adapter is an Eelco. Thanks!
