Hey all!

I just realized I have a PERFECT 1956+ 235 st a family members. PERFECT. I wouldn’t mind it behind the BOP 200-4t my buddy is selling me on cheap. But I’m assuming such an adapter, if it exists, is absurdly expensive?


I looked at a 292 yesterday that was no good. May have a 230 lined up but it’s 6 hours away… not sure exactly what I’ll end up with but I know it’s a six and I know it’s an overdrive automatic. And I pray it’s not $$$$$$$. I can’t wait to drive my car again

I purchased an adapter from Langdons for my 200-4r

You should be able to find a BOP adapter to Chevy 235 engine for around $50. It's just a plate.

Really!? Everybody says, not just here but all over the Internet as I Google, that it is absurdly expensive to put a turbo 350 Chevy transmission behind one of these 235s, I assumed it would be even more expensive to put a BOP 200 4r


I watched some YouTube videos last night about guys making their own adapter plates for Crazy applications, like putting LS with Toyota transmission, one guy put the 2.6 L turbo Nissan skyline engine with that new six speed Toyota in that little car that’s a joint venture with Subaru… They made them with basic tools. Precision came from finding center punches the exact same diameter as the dowel holes…

That said, I thought that was my worst case scenario. I can’t even find BOP-235. I guess I’ll see if Langdon has one… Thanks. Feel free, anybody, to post one if you know where one exists. Appreciate you all

Langdons kit cam with a new starter, flywheel, plate and the hardware. I'm sure there are others out there.

Make sure to grab a 2004r with both BOP and Chevy mounting options. That's what I did... Although I might go with a 700-r4 now.

By the way, the reason I am bouncing around a little bit I should share:

I want a 292 and an automatic overdrive. But the 292 is just for the cool factor. I don’t need the power. A 250 or a 230 will work

I have a pretty much brand new 1956 235, and I’m trying to get a guy to sell me a three speed Borg Warner overdrive for a realistic price (all of these parts I am talking about are a very little value, but Facebook marketplace has ruined this hobby)

The missing piece of the puzzle? I also have a 1954 Chevy truck that I am going to put together. So if I found a really good deal even on three or 46 cylinders and a couple extra transmissions, between those two cars, building them, and keeping them going for the rest of my life and hopefully my sons, I would jump on anything that kind of makes sense lol

What I’ve got so far other than a major bug up my butt to drive my car this spring, is that 235 and a metric 200 Oldsmobile transmission… I’m not opposed at all to using them together, if that’s what it comes down to.

I think using that 235 gently, and maintaining it with good oil etc., it should give 100,000 miles like anything else. Yes the 230 and 250 and 292 are much better motors, but that doesn’t help if I can’t find one ha ha

The metric 200 had a lot of failures. When I worked for GM, the reverse planetary shell was a common failure, putting car in reverse, cold at high idle caused most of the problems. Stripped the splines or the lugs in the housing.

Steve at Buffalo Enterprises makes a very reasonably priced adapter to put a 200R4 behind a 235 or 261. I used one of his kits, which I think also came with a modified flexplate as well, when I put a blown 261 in my 54, 210 two door.
Worked very well and Steve's parts are right on.

Thank you! At least that gets me down the road if I don’t end up finding the newer six cylinder that I want.

The 50 sedan will definitely be getting some big miles put on it, so I hope to find a 230 or a 250. The old truck is more just for Going to the garden store or Lowe’s or whatever. My wife stole my tundra

Overall it was under engineered, not well designed in gas applications for engines with moderate torque potential.

Shepherd which that truck. You can tell it was engineered by the same guy who made the Camry so smooth and reliable but it is a monster with towing, and it doesn’t mind going off the pavement.

I’m not exactly sure how the dust is going to settle with this one. I think she is going to end up in a 1 ton GM or Ford, crew cab six passenger with the medium size box. or a sequoia. She’ll realize real quick my “Double cab“ is a little bit tight with all six of us

Boy this is quite the adventure trying to lineup all of these parts. 10 years ago, when I built this car, these six cylinders were everywhere for just about free because nobody wanted them, and the transmissions weren’t hard to find between two and $400. Seems Facebook marketplace, as well as just all around deterioration of human communication has ruined the hobby a little bit

Oh yes! The longest time I was trying to avoid them and the 700 thinking I would just do 4L 60 E and get a computer and throttle position sensor, but it’s pretty darn cost prohibitive, and even if it wasn’t, I want to go back to Simple. I will definitely look up how to adjust those cables. This spring I have to do it on a vintage Toyota, that’ll be my practice

Drew,
I thought you had a small block and auto trans in your car now ?

If so, a 230/250 6 cyl. would be a bolt in installation with exception to the radiator/water pump clearance.

Good memory =)

Not thinking I want to use a non-overdrive which is why I think I'll shelf the TH350. Its got 22,000 miles on it give or take so worth saving.

I think 250 and th200-4r is the way i'll go. Might just throw a 3 speed and '56 235 with open drive and a 3.08 in the 54 truck. Those 3speed overdrives are fragile I hear, and very hard to find

Drew, Both 200/700 transmissions would be ok for the type of driving you do. As I remember, you just want to cruise and occasionally goose it once in a while.

I ran a 700R4 behind my built 327 with 411 gears for 6 years. Never had a trans problem. I did have a transmission shop look it over before hand and install a manual converter lockup valve. No electrical was needed for lockup then.

If you can get your hands on either transmission, I wouldn't be afraid to run it. Just make sure the kick down cable is correctly installed to maintain the correct pressure in the trans.

With the 411 rear gears in mine, she was at 2300 to 2400 rpm's at 60 MPH in overdrive. It had all the power you needed during take off too. Something your 6 cyl. is going to need.

I should add I was running a tall tire too. 28 diameter if I remember correctly.

Thanks!

I lined up a 3.73, which will free up my 3.08 to go in my truck which is looking like it wont have overdrive. Oh what I would give for a month in a larger heated space with both vehicles and the parts to do what I want. Maybe thats my garage in Heaven. Sure aint here haha

I was going to rig up an automatic control for the lockup. I think I remember how to do it as I almost used a TH350c (350 with a lockup)

The one on the right, see how the top of the bell is a swoop like a suspension bridge? That’s the BOP pattern. I’m sure General Motors had their reasons, but from where I’m standing at this moment, an unnecessary complication of things lol. The one on the right is the standard V-8 bells housing from Chevy. Should be the same from 1955 until now-ish. At least 6l8e I think. The 63+ i6 too. 194/230/250/292

I don’t know if there is a bell housing that can adapt to your desired engine, but there is an R11 transmission on eBay right now.

that would definitely be for the truck, if anything. The truck is going to stay a manual. For durability sake, I was just going to run a regular three speed and use 3.08 gears, 3.23 or 3.55 if it doesn’t have enough get up and go. I would love to have one of these, and run 373 gears. That’s the best of both worlds, but I hear these aren’t particularly durable… And with how rare they are and how expensive they are, that might be a bad combination. I just do not want a stick coming up through the floor, or I would put a five speed in it and be done

Yeah… I’ve already ‘grenaded’ my overdrive twice now. The overdrive planet gears are not tolerant of low oil level and will overheat and deform if oil leaks aren’t addressed. On the plus side the other components were able to take the huge shock loading of the overdrive planetary gears locking up at 75 mph and automatically downshift to direct drive without shearing the driveshaft. It did put a good twist in my unhardened modified output shaft though. I’m going to have to tear down my destroyed gears and identify if the planet gears have needle bearings or a bushing of some sort. They may just be hardened steel riding directly on a steel pin.

that SUCKS. Its such a shame they are rate and weak becuase overdrive is probably more important to most than power steering or brakes - the latter two are used maneuvering around but the overdrive is the ENTIRE time you are cruising. I will LIKELY be able to report back and say how a 1956 235 and 3 speed does in a truck with 3.08:1 gears. HOPEFULLY well. I know with 27" tires, 3.08 is tollerable on the highway. But thats with a v8 that doesnt suffer in 1st gear. 3.73 and 0.7:1 OD would be delightful



nevertheless, stock up on these transmissions if its your choice - everything is getting rare and facebook marketplace mentality is destroying this hobby the way facebook mentality is destroying society

Well, for your truck I would probably think about using a 4 speed transmission with granny gear and possibly a 2.73 gear from a Nova supposedly. I assume you’re going to replace the torque tube rear axle for something more modern anyway. That gear combo should be close to the equivalent of 3:55 with overdrive. In my car the overdrive ratio is excellent for cruising at 75 mph, although the car has just a little less torque in 1st gear than when it had 4.11’s. I’m not sure if you intend to be pulling stumps with the truck, but using a granny gear 4 speed with a tall rear end should be just fine for cruising and light hauling.
