kencombs Posted October 29, 2007 Report Share Posted October 29, 2007 I don't have a P13 or D24, but do have a Mopar flathead 6 in my '56 pickup. Like a lot of folks, I feel a need to drive faster but run the engine slower. I am working on getting the clutch housing that uses a hydraulic slave cylinder to go with the hanging pedal setup that I plan on installing. These housings have a larger trans mounting area than the stock one so I have lots of room to drill new bolt holes. The overdrive I am currently planning to install is a New Process A833 from a late 70s Mopar. They were used in pickups, vans and cars. I want to use a floor shift so the stock overdrives are pretty much eliminated because of the shifter issue. Nobody makes a floor shift for the old selector shift mechanisms that Chryco used, along with Buick, Olds and a few others. So I considered other overdrives, Saginaw electric on a full sychro trans and a T5 among others. Has anyone tried the 833? any feedback? It looks to be a fairly easy install, other than the parking brake issue. Am I missing anything? Quote Link to comment Share on other sites More sharing options...
Young Ed Posted October 29, 2007 Report Share Posted October 29, 2007 Only thing I've ever heard people having issues with is the shift linkage on the side. One of those is on my possibilities list for a tranny swap too. Quote Link to comment Share on other sites More sharing options...
James_Douglas Posted October 29, 2007 Report Share Posted October 29, 2007 If I was to do it again..I would either get a gear Vendors OD and/or put in a push button 727 with a Wilcap adaptor plate. James Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted October 29, 2007 Report Share Posted October 29, 2007 James..given the Wildcap adapter approach..if indeed you should in the future elect this unit..may I recommend a 1990's A518.....it is the basic 727 with overdrive and the overdrive is automatic and can be locked out with the push of a single button...or for your car the A500..basic 904 with OD....I have a few of these around the house and within the family..they are great...mind you if you do not use the Chrysler rated +3 oil..you will have trouble and there is NO SUCH THING as an additive to bring Mercon up to Chrysler specs..I know your 6 will not meet this but towing with my B250 van, 318 with the A500 (904) I can cruise at 70 in OD with 5000 pounds behind me....just saying you will not be hounded to death like the R700's bouncing in and out of OD...

rearview Posted October 29, 2007 Report Share Posted October 29, 2007 Tim... would you need 12v to run those? I was ready to shell out $$$ for a factory unit, but I want flexibility for a future (hemi?) motor change. Quote Link to comment Share on other sites More sharing options...
Tony_Urwin Posted October 29, 2007 Report Share Posted October 29, 2007 This A-833 link is from a previous forum post: http://hometown.aol.com/erlihemi/PwrGiant.html Quote Link to comment Share on other sites More sharing options...
James_Douglas Posted October 30, 2007 Report Share Posted October 30, 2007 I think if I ever put in another engine, I will use an early Hemi and a push button 727, with a GV overdrive. James Quote Link to comment Share on other sites More sharing options...
kencombs Posted October 30, 2007 Author Report Share Posted October 30, 2007 Only thing I've ever heard people having issues with is the shift linkage on the side. One of those is on my possibilities list for a tranny swap too. Yep, there were two different shifters used in the stock vehicles. One made by Inland and the other by Hurst. Chrysler sourced the better Hurst and they were just trouble free. I had a few of them back in the 60's-70's in Darts, Valiants and a couple of big blocks. But, the Inland is another story, get a Hurst. Quote Link to comment Share on other sites More sharing options...
jimwheeldon Posted November 1, 2007 Report Share Posted November 1, 2007 Has anyone switched to a small block Mopar(318 or 360) with a conventional 3 spd auto? It seems like it would be fairly inexpensive and readily available. I'm not ready to give up on my old flathead..just curious. Quote Link to comment Share on other sites More sharing options...
Plymouthy Adams Posted November 1, 2007 Report Share Posted November 1, 2007 I have mine fitted but not on the road yet..got a 3.9 V6 with A500 auto OD and 2.94 ratio rear gear...and the other is a 360 Police Interceptor backed by a 727 auto and 9 1/4 inch posi with 2.88 ratio..however for the record I have swapped to a late model Dodge clip..and engines MUST be remounted even with that due to offset..and of course the 41 with the 383 and 727...
