Distributor Options for your SBF

I get a lot of questions about SBF distributors, so I put together this video describing three different options - points, electronic, and dual sync fuel injection trigger. There's no universal answer as to which is best because all have pros and cons. The best answer for you depends entirely on your specific application.

i run msd-8598 with 6-a box on my 347

Nice, that's what's on mine right now. I'm partial to MSD, so I'll probably use their dual-sync when I install my fuel injection system. Thanks for watching!

so am i like your channel@@billsgarage

Very thorough explanation, thanks

You're welcome, and thanks for watching!

The second distributor is not electronic, it’s a passive inductor and it is Hall effect. ( no active electronics involved) it is used to interface with an amplifier device ( MSD 6 AL or similar) ….. and on that note, be warned that MSD now has their consumer distributors made in China. Their failure rate is high.

MSD Distributors like this one are not Hall Effect, they are Variable Reluctance, as evidenced by the fact that there are only 2 wires on the sensor, as opposed to the 3 wires necessary for a Hall Effect sensor to operate. All Variable Reluctance sensors have 2 wires, and all Hall Effect sensors have 3 wires. Some of the newer MSD models do use a Hall Effect sensor, but not the one that I described. This type of distributor is an electronic one because it can't be operated without transistorized microcircuitry. You don't have to use an MSD box, you could use a Ford Duraspark, GM HEI module, or something similar in order to trigger the coil, but you can't trigger a coil directly with a Variable Reluctance sensor.

I didn't like the points, wouldn't stay set, the early HEI was a god send. Never had a problem from the early Ford units.

I ran an HEI for a while, but kept blowing modules. That's what convinced me to switch to MSD, and I've been really happy with it. Thanks for watching!

@@billsgarage Wonder why, I've never blown a module. I plan to try MSD soon.
