Re: A833 OD questions

[Dave Casey <dcasey@xxxxxxxxxxxxx>]

I've been out of town, otherwise I'd have chimed in sooner.
I have an 833 OD in my '65 Polara (C-body, but uses the same trans as 
B-bodies).
I used the truck/van version of the OD.
Fourth gear is something like 0.74:1.
I solved the bearing retainer problem pretty easily.
I removed the retainer from the trans and chucked it up on a brake lathe. I 
then turned down the outside diameter until it fit my bellhousing. There's 
plenty of meat on the retainer so have no fear (but at least look at what 
you're doing, because you might have a smaller bellhousing than I).
I pieced together the shifter linkage and had to make some adjustments to my 
handle because I had the wrong shifter mounting pad, but it works great now.
I've had it behind my 413 for three years now with no problems. It has seen 
plenty of highway cruising in overdrive in that time. It has also held up to 
being driven hard in a 5000 lb car, but I don't dare powershift it.
I'm running a 3.23 in the back with 255/60R15 tires. First gear is pretty 
low, so you'll probably prefer to take off in 2nd with your 3.91.
Also, the gap between 1st and 2nd is pretty wide, so the shifting isn't as 
fast as you'd like it to be since you have to wait for the input to spin 
down or double clutch. Shifting 2-3-4, or even 2-4 can be done pretty fast. 
Second gear is my favorite because my engine raps out at about 70mph in 
second (cast pistons, don't turn it past 5000). If you're spinning to 6k, 
then first gear might be a little more useful and second will be a blast.
