What rear & trany did they put in the HEMI A bodies. 4spds, automatics, rear housings, center sections. Also- what did they run in the 1/4 right out of the box. These questions have probably been asked & answered & I should know this stuff. So send me back to school so I can answer that question I was asked this past weekend. Sorry my bad, I am talking about the Hurst Hemi A bodies Barracuda & Darts

My dad had a wO23 67 street hemi. I believe it ran 13.0 on the original street tires it came with after driving it 17 miles to the track.
 
It came with reverse valve body automatic. Gears no idea.
 
i believe they all had 8 3/4 rears not sure about the hurst
hemi cars
 
Super Stock Hemi Darts and Cudas had 8 3/4" axles if equipped with automatic, and Dana if 4 speeds...

They ran about 10.3 right off the trailer from the factory...

That is very interesting ! I have a friend w/ a 68 dart 440 running in the 10.70 area. He is running a 8 3/4 rear. Everyone is telling him that 8 3/4 will never hold up.

Bullet proof to about 600 hp.
 
The Dana 60/4-spd cars had the A-833 4-speed (2:66/1st gear, 1:91/2nd gear q:39/3rd gear, 1:00/4th gear) and was "slick shifted" from the factory. Rear gear for them was 4:88
The automatic cars used a 727 modified quite a bit , the most notable being the reverse-pattern valvebody & a 2800 stall converter. The used a 4:86 gear in the rearend.

Automatic cars used 8 3/4 rears ?
 
Yup! Apparently Tarozzi, et al thought the auto would absorb some of the driveline shock so they went with that. Keep in mind this was shortly before trans-brakes so all they had was high-stall convertors.
 
Does any one know what they ran in the 1/4 before some of the race teams got there hands on them ?
 
This is a copy of a post 69Cuda440 posted on a forum some time ago.
I hope it is all wright to do like this. Otherwise correct me, and I apologize

What Did The 1968 Race Hemi B029 Barracuda or LO23 Dart Run 'out of the box'.

clip_image001.gif


1968

Just what did the 1968 BO29 Barracuda and/or LO23 Dart
426 Race Hemi's run.

'Out-of-the-Box' and with no modifications, and with 10.5" Slicks
on 15" x 8" Rims.

11.40's @ 120 MPH

Remember, these 'A-Body Bombs' were delivered with 'stock'
426 Street Hemi 'mechanical' Camshafts.

The NHRA 're-factored' these engines to 525 Horsepower, and classed
them into SS/B and-or SS/BA {6.00 to 6.99 Wt/Hp} for 1968

I had a 64 B-Body NSSA car that ran 10.0s with a 500 inch Max Wedge. I folded up an un-braced 8 .75 like a cheap set of monkey bars. I went Dana 60 and never had a problem after that. IMHO 8.75s are for street cars.
