Can anyone tell me how much of the transmission tunnel / Torsion bar support needs cut to go into a b body? I very much like the idea of this transmission for a relatively high power build, and the electronic control options.

Thanks for any advice.

Blasphemy, of course, but I can certainly see the point. The only Mopar option is to use a 727 with a Gear Vendors OD or a 518 with an adapter and the OD unit on them is weak. But if you were to go with a 5.7 Hemi you could use one of the 8 speed truck automatics which are better than any of the GM offerings.

Back to the question...cut as much as you need to cut and as long as you are at it ditch the torsion bars for a modern suspension...there that ought to stir the wrath of the righteous faithful.

I can't tell you how much has to go, but the electronic control it offers is, as you say, very attractive. Will be interesting to see eventual info received.

I had one in a 65 Belvedere that needed the support cut out in the trans tunnel, trans mount modified and the collector on the TTI headers moved. I love it behind the a 500" motor. It was a Phoenix trans and computer and adapter. I sold the car but still have the trans set up and 500" that will be going in another 65 Coronet. The best part about it is you can set the shift points and the trans would shift itself bracket racing. It was considered No E because all the new cars use the same computer.

I would love to run the NAG1 but it doesn't look like there are controllers to make the swap worth it. THe 4l80E has the controller.

friend of mine has one behind a bb cheby, its been in the 8's and is street driven all the time. never had one issue with it. I think it was a art carr build. easy 500 passes on it. they are tough

Run it, its a TH400 with OD, very stout.

NAG1 controllers are available but the trans aren't nearly as popular in junkyards around my area. They seem to be smaller and lighter.

I've got a 4l80e and wilcap sb adapter that will be going in my Duster with a megasquirt based trans controller.

Have you figured how much cutting you will need to do to put it in your duster?

I love it!!! Another pioneer not afraid to think outside the "Mopar or No Good" Box

I have no experiance with shoe horning any of these trannys into a Mopar, but I can tell you a 4l60 is smaller, lighter, has a ton of aftermarket support, and the bellhousing unbolts from the case. There are a couple of manufacturers that have Mopar bolt pattern ones out there, big and smallblock. Mike

Yeah, Im pretty messed up. I also run 9" stuff in 4 of my cars and enjoy the ease of swapping the different 3rd members. When mopar guys start hassling me about a ford rear end I ask them to find a ford part on it. The only Ford part is the bolt pattern.
