What is the "Bailey treatment"?

What Bob said.

Having your ring & pinion "FINISHED" will not only make it live longer, but I've found that it's worth a couple hundredths, too!

REM Isotropic Superfinishing plus Cryogenic treatment. There's some info on his site, finishedracing.com

yea Richmond has a part number but they stopped making them, told us we need an order of $10k to get a set, oh well Jim Baileys stuff has held up better then anything i have ever bought from Richmond. Also the 8.75 rear is great if its set up correctly i've been 10.7's @ 3200+ lbs and no prob with the rear just the richmond street gears.

Bob, No I am not going to use the 8 1/4 behind the hemi. This question is for the slant six wagon. I have a garage full of spare parts for any rear axle I use I'm just wondering if I will gain any ET by putting a 8 3/4 under the wagon, The strengh is not in question.


So is a 8 3/4 faster than a 8 1/4? anybody have a real answer?

Re: Mopar 8 3/4 VS 8 1/4
 

With the limited choices of ratios for the 8.25 if the optimum gearing for your combo turns out to be between those ratios and it is available for the 8 3/4 then the latter would be the rear assembly to use....I think that any small benefit (if there is one) in performance with the same ratios in each would be overcome by the flexibilty of the 8 3/4.....
