Are there any trans swaps that would allow me to retain a functional factory slap stick? what are my options? Thanks.

A 518 from a Dodge van or truck would allow you to use your Slap Stick shifter. You will have to fab a bracket to hold the bottom of the torque shaft that goes thru the floorpan though. There is no provision to mount the stock bracket that bolts to the bottom of the tailshaft of a 727. I plan on using a 518 in a Cuda that I have as a future project.

Will that unit or the A500 trans fit the tunnel?

Who was the guy that used to post here that had a B-body with a 518 and a turbo'd motor? He did a really good job of modding the crossmember. You can cut on some of the bracing on a 518 and it will fit the torsion bar x member. I honestly don't remember seeing pics of a 500 installed in a B or E body.

I've been researching the 727 to 518 swap for a few weeks now and the 518 is really probably going to be the best bet if for no other reason than the OD is electrically actuated.

With something like a superbell on a 700R4 or other off brand OD the slap stick would require an additional detent to engage all the gears.

The 518 is also a whole lot better option than a gear vendor bolted on to the transmission.

For what it’s worth to give you an idea on size here some pictures:

And Gear Vendor

Not looking to steal any thunder from this thread but I have been contemplating alternatives to a 3sp auto for my Dart project. I am pretty clueless as to what is out there and what will work, so I will ask here.

I would really like a 4sp auto for my SB, so what are my options, which are the best options? Gear Vendors sounds interesting but I am not fully versed on the pros and cons of GV either?

At one point the GV was the "hot setup" but that was simply becasue it was the only option out there that retained the 727 transmission. Floor pan modifications to get it in were pretty extensive.

The GV unit by itself usually cost more than a rebuilt 518 even without a core. Additionally depending on which version of the 518 you choose you can also get the Torque Convertor lock up feature.

Not to long back there was fellow that sold a '68-ish Valiant with an advertised 518 trans swapped in. The E-mail address with the add was (I think) Jarnos@msn.com. I thought he was possibly connected to the Vignogna (SP) family. This might be a good place to start seeking information?

Anyone have reveiws on the Keisler unit?

Mopar Action put a Keisler in a BB Road Runner and seemed to like it.

518 can be done in an e-body without cutting the floor:

Just to be clear on the option, there's no extensive floorpan mods in an E body using the Gear vendors..Only the electronic speedo convertor area may need a touch of help...

I've performed the Keisler E/B body Auto+4 swap, no floorboard mods are needed, everything is included in the kit, the slapstik is retained, and converted to cable shift, you do have to disassemble the slapstik unit to install the new detent plate, but the shifter retains it original feature, just ads the O/D into the shift, you'll need to mod the factory transmission lines to tie into the braided SS lines that are now on the passenger side,...there is an addition of a TV cable (Throttle Valve) that must be used, basically like a kickdown linkage, but cable,...there is an onboard computer module also, that can be interfaced to reprogram line pressure, shift rpm range, band apply, etc,......the price has come down from it's inception, the final O/D ratio is .70

MORE charity from DAYCLONA! I just read about the Blue Dart in Mopar Action. Nice deed. Nice job.
