I can't wait to hear about your results with the 700R4.  I hope you'll take the time to tell us about anything you had to do to get the different transmission mounted.  Also, are you running a controller for the transmission or can you make it lock up manually some how?

Got the adapter plate from Bendtsen's in Ham Lake Mn. 763-767-4480 bob@transmissionadapters.com ($415)This is for the 429 no mods necessary. Use your flywheel and starter. Now remember guys I have a 65 Hearse it had the TH400 so I'm just going to assume your mount system is the same as mine. The 700R4 is a little wider then the 400 so you might have to notch the floor on the side of the fuel pedal only about 2in X 2in. I remade my crossmember just using 3 in channel iron instead of the original trans mount. The channel get mounted under the frame not on top, I welded 2in angle on the side frame and drilled more holes so there is 4 bolts on each side holding up the new crossmember welded a 1/4 in kick plate off the front of the channel for the transmission mount, transmission mount is from an 81 Corvette. I have a split driveshaft, had a new one made to fit ($185) The torque converter is a lock-up you can hook it up a few different ways, mine is hooked up so when you  put the brakes on it unlocks or you can put in a separate switch and manually do it. Your exhaust will have to be re-routed, whatever carb your running make sure you have all the adapters for the de-tent cable to be aligned properly as this controls shifting. Will all this be worth it. I assume the fuel milage will increase but to run down the highway at 70 and only turning 2200 RPM will sure help the engine. Well have to go back to work now putting a 25 gal gas tank for an 85 Balzer in it now. I kept everything and can convert back but I doubt I will.

Awesome Brother.  Thanks for the information.  Sounds like a great way to go.  I'm going to have to see if I can find a 700R4.  I think the extra low 1st gear will also help in getting the 5000 lb. sled moving.  I'm not really worried about the trans crossmember nearly as much as I am the wiring for the kick down for the converter.  Sounds like you're using a stock converter?  If you get time some pics of the installation would be great!!!  Thanks again.

One side bar when looking for a 700r4 get a 30 spline converter type the later model not the early 27 spline.   Jerry

No it's not a stock converter, wiring in the trans is where a lot of it is but they make kits for this Mine is a 92 trans you have to get anything later then a 85 for the good trans. I had mine completely rebuilt all heavy duty with shift kit and lock up kit

Took the Deadsled out yesterday with the 700R4 what a difference seems like a different car any one not wanting to keep a factory correct car, I would recommend this to you. When weather gets nicer and I start driving more will give you  updates on mileage.
