[DeTomaso] Sequential gearbox for the ADA pantera

[Ken Green]

The only "Clevor Block" I know of is the Fontana Block.  It's a mix that uses a Cleveland oil pan and a Windsor timing cover, etc.  I think the SVO block is basically a 9.2 deck Windsor with extra metal to make it strong and maybe set up for dry sump.  I think the general term "Clevor" applies to Cleveland style heads on a Windsor block.

Patrick,

	This looks like a Clevor block that uses the cast aluminum 351W front
cover.  If you use a 351C type intake manifold that doesn't have a
thermostat housing cast into it, you'll need a remote thermostat housing.
If you need a remote thermostat housing like the one I used on my Clevor,
let me know.

As some of you know, I purchased last year, the very well known ex ADA
Engineering Le Mans 1994 Pantera VIN  9628.
The car needed restoration, and was missing engine and gearbox.
Now that Candy 2862 successfully finished Le Mans Classic, thanks to Mad
Dawg's Team Pantera stickers  :>)) I now start to concentrate on the
rebuilt
of the ADA Pantera.
For those who want to look at some Le Mans Candy pics, please go to

I have found a proper solution for the ADA engine, presently being built by
John Christian, but so far, I haven't been able to locate a proper
sequential gearbox, except some brand new magnesium Hewland NLT, extremely
costly.
I consider other alternative ( and possibly cheaper) solutions by looking at
what the second hand market can offer, in other brands too ( Xtrac, Getrag,
Ricardo, and so on )
You can find details over the "good Ole'351C " block I bought for
ADA on
http://www.fordracingparts.com/parts/part_details.asp?PartKeyField=9362

Now, here is the requirements'list for the intended gearbox

1. it MUST be sequential, 5 or 6 speeds ( considering the torque, it
probably doesn't make such a huge difference on long race tracks)

2. it must fit the Pantera engine and drivetrain.

3. it must be capable of supporting the intended enormous torque and power
of the engine.

4. It must be very reliable ( the car always had gearbox problems, even with
Hewland, and even when the Hewland gearbox was finetuned by the March F1
gearbox engineers )

5. spare pinions must be easy to find, in order to adjust the
gearbox'ratios
to the racetrack.

I've been told some Porsche gearboxes could be adapted, but that the
baffles
were upside down, and so, useless ( True or not? I am uncompetent in this
field ).

Luckily, the GT90's revival organizers allowed me to race the car in its
last 1997 specs, and considering the competition and the other cars in
presence,( McLaren GTR, Ferrari F40, Porsche GT1, Mercedes CLK GTR, ... any
improvement to the ADA car, with modern technology, is not only welcome, but
important.

Many thanks for your help and suggestions.

Patrick
