I know this has been beaten up as a topic but no realy good info on the adapter plates them selfs is out there. I dont trust a bell that bolts to the pump it self. So I am just wondering if anyone has pictures of the adapter plate bolted to a big block and or how it works. I got a rough idea and I am thinking about making my own adapter plate I will be doing a build on this tranny and may ask more questions as I do It.

Yeh hey thanks for the quick reply they never gave much infor on the plate it self. So half inch hu? is it aluminum? I could quite possibly machine it my self. I build my own intake and efi with a megasquirt kit. I will probably have the ecu control the overdrive. I have a 92 a518 non lockup and 2 727 bigblock trans and another 440 block to fit everything with.

Yeh thanks I belive I have read all the posts I can find on here and other places on the net and I think the bell that bolts to the pump will cause my pump bolts to work loose as time goes on. I am making some serious power just want to have perfact gearing for the 1/4 and a overdrive to cruise in.

Noticed your looking for an adapt plate.. not the bell  I'd be interested to see how a 518 stands up for you behind real power... Think it's been tried with  results Good luck

Does anyone know if the 727 big block tranny torque converter fits a 727 small block tranny?

I think the adaptor was machined from a big sized plate, and it uses unique bolts that have about 1/4" thick head and screw in with an allen wrench.
The plate re-locates the starter position, so a notch has to be cut in the transmission bellhousing for the starter.
Let me know how the megasquirt works out, I might try that in the future...
So the bolts that thread though the plate to the origanl tranny are counter sunk? I love the megasquirt it has endless capibilitys but kinda like the overdrive conversion its not for every one its alot of work and alot of learning. But a big part of the reason I did it was to learn I have about 3000 miles on the megasquirt and still working out bugs But I built it with 4 throtle bodies staged and a staged 16 injector system as well. I just installed launch control and hooked it to the brake lights for now so when you push the breaks and push the gas it hits a soft rev then a rev limiter and you can basicly pin the gas and once the brake light shuts off you are gone! I have it running the 3 electric fans and electric water pump. set lean at light cruise and full perfact 12.7 at wide open. To much to talk about it has been about 2 years of work so far but I love it there is nothing cooler then building something fast then tring it out!

I havent herd of any coming loose, but also havent herd of much for miles on any of the bell users, and not to mention how much power do they make with there cars driving styles? I like to drive hard and put alot of miles on. I am just trying to be cautious. How hard are they launching? twisting on the pump bolts? I would have more faith if a couple guys with big power big blocks had some good runs down the 1/4 and lots of miles on the highway.

I've got the Ultrabell/440 combo. Haven't cut the bell off yet. What's your reasoning for the pump bolts coming loose? I've worked on jet engines held together with 1/4" fasteners torqued to 65in-lbs. They don't come loose. The flex plate to torque converter uses those four little bolts, and the driveshaft has those four 1/4" bolts with all the engine power going through them, and they don't come loose or break. I don't think the pump bolts have that much going through them. Isn't the Ultrabell most often used on race cars for safety reasons?
I am not trying to be a jerk just being cautious and want to see some results before I jumped into a ulta bell. But as for the drive shaft bolts they dont take the stress of the twisting force the yolk does, where as the pump bolts on a ultra bell take all the twisting between the tranny and engine and hold the engine up in the rear and the tranny up in the front.

I got an Ultra bell coming some time this week. I'm going to use mine in my tow rig behind a 446 c.i. mill.

performance does matter to me but I hate driving a 2000 mile road trip the putting the car up on stands and pulling the diff out and changing from the 2.76 gears I have to the 3.91s that are perfact for me for the 1/4 and driving for the weekend then changing back to drive home not to mention having the 3rd member roll around in the trunk and smash out my 1/4 pannels. Thoses guys might think you will loose 1 second in the 1/4 but PROVE IT! I will be going from the 3.23 gears I have now that arent that good for the 1/4 and suck on the highway reving 2800 at 60mph to 3.91 that are perfact for the 1/4 and will rev 2350 on the high way in overdrive. I took my overdrive compleatly apart last night and found the overdrive section is heavy like ~20 pounds and that is spinning weight (which on an inertia dyno will show less horsepower but wont make a difference on a steady load dyno both taking readings from the rear wheels) As for the "you should be driving in you peak tourque for best mileage" topic (this topic will probably come up soon) it is also not true simply because the engine is more powerfull then the car needs. I could understand it being true with a engine designed for the car to be delivering the best gas milage. So in conclusion if you build the whole car to use the overdrive properly it can show gains in milage and performance!

Pat has adapters at SMR transmission.
Another thing is according to Pat the 518 is very inefficient. Moving to a 518 will take about 1 second of your quarter mile time...If performance matters to you.
Show me the tests!

Fellas as this is a forum for information and I'm not the tranny expert this is how the story goes. I was just talking with Pat at SMR and we got on the subject of the 518. He is the one who said it will lose the second so if you don't take my word call the trans man himself. Maybe he can convince you. 
http://www.smrtrans.com/
What i am tring to say is the tranny they used as a three speed, was it geared the same? Did it have the same stall speed? Did they use the same rear endgears? If they used the same rear end gears then were they pulling full rpm throught the traps? If so then with those gears they will be at a pretty hi rpm on the highway at 60-70mile per hour. If I geard mine to run the best in the 1/4 I would use 3.91 rear end gears. If I used the 3.91 gears for a 1/4 mile run with a 3 speed and a 518 I would be willing to bet the 3 speed 727 would turn a quicker 1/4 time because the car would weigh less and there would be less pasasidic drag in the tranny. But With the 3.91s I would rev 3400 rpm at 60mph in 3rd with a 727 Or I can just use overdrive and cruse home or instead I could pull over to swap out to a 2.76 that still revs higher at 60 then the 518 with 3.91s and would more than likely burn more gas on the way home. Then if I was one of those people who has a instance that I wanted to have some fun on the way home I could have a faster car to do it with because I still have the low 1st 2nd and 3rd that the 3.91s give me.

I didn't get any pictures of it yet, but it did come in yesterday. I'll be cutting the old one off this weekend.

Well no, but I was tripping on it too. Really though it was too easy. I did take some pictures, but I don't have them where I can post them yet. Sorry.
I'm working right now on welding the shift linkage tab and the kick down tab on the bell housing and drilling the new holes in the frame for the OD crossmember.

I am almost done building my adapter plate. I decided to build one from steal so I can keep it thinner. I will weld the studs in for the tranny and use short head bolts to bolt the plate to the engine and machine a bit into the tranny housing for the bolt heads that thread into the engine. I figured out you have to use the 727 position for the starter. And I lucked out and got the 360 magnum tranny with the high stall. It is a 10.75" converter that just might stall out were I need which is ~2400 rpm to still be streatable. Mine is a non lockup so thats what I will have to limit my stall at for now. It should rev at 2350 with 3.91 gears my 26" tires and about 200 rpm slip at 60mph like I had with the 12" 727 converter. I will take pictures tonight. I also figured out I have to cut the welds on the starter gear and slide it back the distance of the tranny adapter plate towards the engine on the converter and I will need to space the tourque converter back the same distance from the flex plate as well. The further you can keep the tranny forward the easer it will fit in the tunnel. I have a transgo shift reprogramer kit and a super master rebuild kit coming with red eagle clutches so I can squeeze in 5 clutches instead of 4. Should be fun!

What did you wind up cutting the case with? That Ultrabell is heavy considering it's aluminum! It is very thick though.

You can buy a milling disc at a welding supply shop that will mount on your angle grinder. It comes with carbide teath on it and looks like a mini skill saw blade. It will cut through the aluminum like butter but be extreamly carefull it will take your arm off like nothing as well. Just make sure you are cutting in the right direction/angle so it doesnt kickback.
