Instead of ordering a new module for your Unilite, you should consider
swapping to Pertronix.  They make a conversion kit for the Unilite.  The
optical trigger in the Unilite won't give you any more power, but it doesn't
like voltage spikes.  I've gone through 3 Unilite modules - twice with their
surge protector.  I've run 3 Pertronix modules (different cars).  They've
all performed flawlessly.

Some people may advise to swap to another distributor, and that's a good
idea too, but there's nothing wrong with your distributor - once you get rid
of the failure prone optical module.

I also like the MSD 6AL, plus the MSD coil recommended for the 6AL.  Don't
get the Mallory HyFire VI.  I had 2 of them go out on me - along with
getting stranded - 2 different cars.  (it takes me 2 or 3 failures to learn
- I'm slow).  I've had great luck with MSD.

You may also want to consider a brand new Holley.  Yes, I know.  It's more
money - but that way you know it's in good shape.  The Pantera vendors carry
Holleys that should be about right for your car.

Do you really need Pertronix + MSD + appropriate MSD coil (you probably
already have this) + new Holley?  Maybe not, but your problems will probably
go away.

Hello Fans of the newcomer .
The saga continues. 1972 detomaso pantera
Here are the findings . 
 
after trying countless times to get her to turn over ....she did but  
...chug....chug.all plugs fouled with gas .
pulled the 4779-7 holley 750 cfm carb off engine and adjusted floats and  
rechecked everything . new power valve,cleaned jets ,new accelerator
plungers... 
 
fully cleaned fuel line and replaced fuel filter 
 
compression check average 115-125 lbs across the board . 
 
i did notice on the carb that the idle screw near accelerator cable is  
tightly closed and car cannot idle faster only slower. Is something messed
up  with 
idle screw mechanism? Could this cause the issues?
 
Found tdc by hand moving engine to tc.Rechecked rotor and found where # 1  
plug should go on cap . 1-3-7-2-6-5-4-8 counter clock wise.Is it possible
the  
firing order for this engine is actually  1-5-4-2-6-3-7-8.I don't  think so 
,just wanted to ask.  
   FRONT OF CAR 
           6       2
      5                 7
        4           3
             8  1
       ENGINE     
Replaced Mallory coil and rewired all connections. Found I had no voltage
to 
the unilite electronic distributor .
rewired all wires to the coil and ballast resister.Distributor now has full

voltage.  
 
Car was now able to start ...still chugging,,,but holding 800-900 rpm and  
smoke....Found timing mark and set timing to 16 degrees. 
 
No change to car...still chugging major hesitation  .
 
I ordered a new module for the distributor . If that does not cure things  
immediately then the carb has to go .
 
I really don't know what else to do ......This past week has me mentally  
drained .
 
Another thought .....When I replaced the radiator,water pump ,thermostat I  
did bypass the wiring harness for the meriah sucker fans and put in new
relays  
for the fans .Could that effect the engine ?  
 
Blown valve? How to check that ?
 
All I can say at this point is...WHAT THE F...?
 
I am open to any and all suggestions
