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!

Hey thanks I am planing a good build for it and I think I will get a bigblock stall as long as I can get the starter to line up.

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.
