Technical Stock distributor performance?

So what's the deal with the LOM distributor?
I read that it need ported vacuum, so why cain't one just drill the carburetor for ported vacuum?

 

Supposedly, even when tuned up and working "as advertised" they are pretty doggy. It's my understanding they used a kind of venturi vacuum for advance, and manifold vacuum to retard timing. Most people seem to be a happier with a post '56 dual advance distributor. It also allows for a different carburetor.

 

So, gut the vacuum advance and run a cable from the breaker plate to the throttle linkage.

 

Really???

Is that possible?

The TFI uses points as a trigger only, so there is very little current across the points. The only wear in the points would be the lobes/follower [which would be considered a moot point]

HEI modules can also be points triggered ,but there is a major difference between the two.
The HEI fires when the points close, whereas the TFI when the points open. So there is no Rotor phasing issues with the TFI.
Most electronic kits available are only "points eliminating kits" whereas the TFI gets more energy into the system.

The original idea came from the HAMB

Anything is possible. If the breaker plate moves then just figure out how else to move it. Would it take some time, sure. A cam shaped cable pull should be able to do it.

 

Yeah, manual advance was a great feature on Model "A"'s.

 

Manual ignition advance/retard from the cabin would be handy at times

 

Boden,

I think most of us have done this. That is purchasing a really neat part and finding out it does not fit our needs. On the contrary if we insist on using it, it can be detrimental to our ultimate goal.

I’m working on a ‘64 Fairlane. I have a vintage Torker intake. To use it would change the direction of the build and it’s a direction I do not want to go.

To use the LOM distributor you will need to run a single LOM compatible carburetor.

Or...

Use an old or newer Mallory.

Use the Ford pre-49 59A crab or earlier distributor. ( requires a early timing cover and camshaft) These had mechanical advance.

Use a machined distributor customized to fit the 8BA.

Use an aftermarket unit with proper advance.
