Technical Aluminium rearend center

I has a 201 QC but I begin to see a cool factor in the style I build as late 40's racer in a 32 coupe to use a std Ford center.
I like ex a chromed frontaxle even if style might say most black painted parts but I'm not into polished Halibrands at rear. ( Shore it's nice but maybe not in this car.
-A question, was it speedparts back then to cast the std units in magnesium or aluminium ?

Did any guys used spools back then ?

 

Hank, this is a N.O.S. Halibrand magnesium "no change" banjo housing.

Yepp, that is the way to go !
Would fit perfect at rear in my std 32 frame, Ardun head FH, Aburn light weight clutch, L Zephyr box, 34 TQ and 36 axle/bones.

 

Always thought the "no-change" housing were for weight savings in a car dedicated to racing in one kinda place; while a quick change was useful for a car that needed a gear change to suit racing at the strip, dry lakes, or the salt flats. maybe even for the road trip there.

 

From the first time I saw one of those "no change" housings in a magazine article I've thought they were very cool.

 

I think they were made for the drag race guys, I don't think you can break them.

My coupe is the concept ’street racing’ as NHRA was not really ongoing.
Me as Hemi guy and racer I do enjoy Ardun heads and race stuff.
This cars is for ’look/style’ but I will use it but no longer trips.

 

The original style center is cool, but not as cool as the quick change. Plus, if you actually drive your car, they are functional.

-Abone.

 

I ran a V8 Halibrand Quickie in my red '32 5 window Hiboy, but it was loaned to me by an elder on the racing team.
(I was 16 then, an 'honorary member')
He saw my car going together, and said "If I loan you my Q.C., you have to use it! Oh, and get a Model A crossmember and spring, too."
Mine was too high with Model A spring, so another friend gave me a '26 T rear spring. I used 5 leaves, and a block on top. Wish I had a pic. (304 flathead, '39 box)

 

Shore the QC is always nice, but a its also ’factor’ to not use one and a magnesium center in a racer feels way cool.
I guess the 7.50 tires is 30” tall and I will use a LZ box ( dont know gears ) but 26 tooth on first gear.
If 4.44 in rear thats 3.000 RPM at 60 MPH and 6.000 at 120.....

 

As originally advertised and used in a slingshot dragster:

 

When was this, 50’s or later or the 40’s ( magnesium )

I has a VW dragster buddy and got this in the ch***ie he once bought.
Look as magnesium but must be 70’s tech.

 

Hank,
I would say you're right. Late 60s - 70s. The coupler for the lower shaft is later tech. The dragster unit is a live axle. The exposed 3" tubes turn with the wheels. That looks to be the larger Champ center. The two ribs close together are a bit unusual.
I'd like to see the article on the 2 speed in a readable form.
