8 3/4 Center Section

[Rod Greene]

If you go with the S60 center section for your dana, it is very easy to have extra gear sets set up and ready to go. They can be changed almost as fast as 9" or 8 3/4. Molly tubes and 40 spline rifle drilled axles make the dana even lighter and totally bullet proof.

Can anyone tell me how the Mopar 8.25" unit stacks up against the drop-out 8.75" in terms of efficencty and weight? I know that a lot of small-bloch Dodge anbd Plymouth racers have replaced the 8.75" rears with these lighter Chrysler Spicer types in the past, but I am wondering about total weight, aftermarket axle availability and strength.

This would be for my 2,700-pound, turbocharged slant-six powered, 904 equipped, bracket car.

Any information would be much appreciated. Thanks in advance...

Can't help on the 8 1/4 but the DANA 44 is supposedly as efficient as the Dana 60. Moser makes aftermarket axles, spools and gears are available. 4 89 5.13 5.38 5.89 that I know of. I have a Summ ers Bros spool available.

Hey Bill, we have a brand new 8 1/4 Strange spool and 5.38 gears. Would let them go cheap.

Bill: The 8 1/4 lasted several years in our 11/12 Second stockers in the
70s. They are lighter and a bit faster. Gear supplies dried up in the
80's with the deepest gear available 4.50. and no 4.80 to be found anywhere.

The slant 6 should be fine unless you re using transbrake and 7 inch convertor.

Last time I ran one was early 1980's. Only gears then were from Mopar
Perf. that I could find. My 1980 Dodge Mirada O/SA is still running a
8 1/4 to this day in stock competitively on East Coast.

I do not know of anyone else in stock although there may be others. The Mirida runs mid 12s at 3620 lbs. and has the same ring and pinion for at least 30 years and three owners.

Larry Shephard told me back when these cars were new when Chrysler changed
from 8 3/4 to 8 1/4....they saved about a dollar a unit!

I am one of many that has swapped a 8 3/4 for a Dana, not done anything else and not slowed down a bit.

Same here in 2 different cars. Dana 60 is one less thing to worry about.
