What will happen if I were to place a Model B distributor, or any other centrifugal advancing distributor atop a NuRex centrifugal advance unit?

by GreynomadI am soon assembling another engine for myself. It will have 6:1 CR, slight cam, down draught carburettor and B distributor. I will be fitting a B timing cover. With that CR, I think I should be aiming at 23° advance. So, where do I set the timing? ie, how many degrees does the B distributor advance and how much advance does the B timing cover give over an A one? Once I know these things, I figure...

by Poor BoyGood morning. I came across a Nu-Rex automatic timing advance . Does anyone have any experience or comments on using these? I printed off the instructions and they appear to be fairly straight forward. It states that there is ten degrees of advance for every thousand rpm, or thirty degrees at twenty eight hundred rpm. I was thinking of trying it on one of my engines, probably the B. How does...

by DaWizardOk, a bit of background first.
As some of you know I have been an advocate for the NuRex centrifugal advance and have been using one for 2 years without issue. Well, after reading the threads here about the advance and needs of the HC heads, I decided I would search for an alternate centrifugal advance distributor.
See, the stock engine with the 4.2:1 compression heads are...-

by alexiskaiI've been doing research for a video on ignition timing, and I realized the Model B's initial advance setting of 19° is actually really high. The Model A's initial timing is 0°, and if you look at the distributor settings for later V8 Fords, their initial advance is in the 2-4° range. Even on modern engines, standard initial timing is usually 10-12°. Why 19°?
The best theory I have...-

by vonheineIn the late 1970s, my friends and I used to hotrod V8 engines. We used to modify the distributor power curves by changing the weights and springs so that the mechanical advance would meet our specifications. We had access to a distributor machine at the trade school from which we all graduated from to confirm the modified power curve. I want to build a simple mechanical advance mechanism for a standard...

by CaptndanWhich way is best, Original with Nurex, Model B, Mallory, or electronic. And there seems to me more than one model of Nurex. Automatic advance is the goal.

I can see from photos and some discussions there are various distributors being used on the Burtz. Can some of you with running burtz make comments on your experience. I am running a burtz with 6 to 1 head and stromberg and a stock A distributor. I think there may be a tendency for the centrifugal advance distributors to over advance? Comments on initial and total advance and idle quality is what...

Now, I know this has been discussed in reference to the FSI distributors and high compression heads, but I need to get just a bit more info on the stock distributor.
I now have in my possession a Snyders 6:1 high compression head and I think since I can't afford a Mitchell OD it will be the next step in the ever changing "Touring Tudor" named Wheezer.
As...-

by slamminGentlemen, as I compile the "wish list" for my new 29 Tudor, the Nurex system is one thing I am considering. I know the purists feel this is an affront to Henry's creation, but I'm not building a fine points winner. I plan to drive the car for a while to get the feel of the Model A as it was designed. I would like feedback from those of you that have first hand experience with the Nurex...

by GreynomadI am currently putting together yet another engine, this time with a 6:1 head. I'm told the maximum advance I should have for that is 22°. I figured if I use a B distributor (I have 3) and set it about 5° advanced, the 17° or so centrifugal advance from the distributor should be pretty right. So much for the theory, now for what actually happened. With timing light and tacho connected, I found...
