Has any one run a D.U.I Distribuor for the 3.9. If so is it worth the price does it work and perform as well as advertised.
D.U.I. distributor
- Thread starter T&M Rover
- Start date
(Driving Under Influence Distributor)
Davis Unified Ignition.
Atlantic British stopped selling them within about 6 months of getting them in. They now recommend the Mallory over the DUI unit. I forget the reason why.

Won't fit without butchering the intake and ancillary mounts. I spoke with the guys at Davis some time back, they assured me it would fit, until I started asking detailed questions and the backpedaled. They were not open to working with me to develop one that would work as a drop-in, hence my exhaustive work to try to make one work.
I have made a Chevy fit, but it was not without its difficulties. I now have an Accel that I'm trying to make work. We'll see how it goes as the summer progresses and I have some time to spend in front of the lathe.

i saw one that Bill at TLR had been doing. LOTS of work. LOTS of grinding. If you ask him, no... not worth it.
I bought one years ago (early 2005). They told me they had installed "thousands" in Rover engines. i swear that is what they said. There was no way in the world I was going to hack away at my rare (carburetted Land Rover) intake to try and get it to fit. Davis as of no help whatsoever. It left a very bitter taste in my mouth.
I went with the Mallory and it performed beautifully. I have not tried the MSD but I know others have had good success with that alternative.

Those who have installed them successfully seem to think it is well worth the work.
Non-serpentine engines require grinding down the corner of the intake and using a cut-down socket head cap screw (at least this is what I found worked OK). Serpentine engines require butchery of the power steering bracket, in addition to grinding the intake.
Many claim all manner of benefits, my interest is limited to reducing impact of water spray on the ignition system. Those who have done it successfully claim they run with water being sprayed directly onto the top of the distributor, but I have no first-hand experience, other than trying to fit various Buick HEI distributors into Rover engines.
what is a( cut-down socket head cap screw) and what does it go to. if posible do you have a pic of how much is ground away and what else is needed to be changed.

Cut-down socket head cap screw-a socket head cap screw that is cut down to lower its profile.
The left-front corner of the intake manifold must be ground down to provide clearance. The power steering pump mount has to have a semi-circle cut out of it to provide clearance.
I installed the Mallory on my RR and it's a very easy swap. The PO had a DUI unit and never installed it because of the interfence issues.

Just curious if it would work with a 4bbl manifold. My hybrids going to run a low profile Offy manifold (the super low one they use on MG V8 conversions). Ive been thinking this might worth doing since we wheel mostly swamps anyway. Gordo.

That link you have goes to a company called Red Rhino and their phone number goes to an old lady in Jacksonville FL that sounded like she had answered a few wrong number calls. Any other source for these? DnD

Guys, I think we are almost certainly barking up the wrong tree with distributors. I can't believe I'm saying this, but I am preparing to go over to the darkside of distributorless ignition.
I have just inquired about having 36-1 trigger wheels shipped from UK for use with Megajolt Lite-Jr systems. I'm about ready to pull the trigger and order the circuit board and parts.
The Megajolt system uses Ford EDIS coils and controllers. In conversations with folks using them in the UK, I'm told this system provides near diesel-like wet weather performance. I've seen pics and video of petrol Rovers in water over the bonnet running like a diesel.
I'm hoping that I can build an entire system pretty cheaply. If it works, it might just be something I can offer to others. It will certainly be less intensive than trying to adapt Chevy HEI units to the Rover.

How complicated is the system?
I looked at the dizzy system seemed to involved (For Me).
HEI is the only thing I have run in the past so I know It works for the trails I run and best of all simple and easy(I mean 3 wire hook up easy) to fix on the trail.
Where can I go to read on this System or any other system that can handle water and mud because that is a MUST for the trails I run.
I think the word circuit board scares me.......HAHA
