Mallory Dual Point Dizzy.......Use it or re-sell it?

Putting together a SBC for a flatty that MIGHT end up in SE class. Mouzer had this thing sitting so I bought it without opening the cap. Model # is YS624MV2. Use it or loose it?

Dunno about the class spec, I'll look into that part. The second question is that I'm a cheap-ass! I was picking up a cheap-cheap Casale and saw it on the bench, complete with cap and wires for $40 bucks, is it not worth the time and $ to make it work?

A possible sugestion-convert the dizzy over to a Pertronics Ignitor III . It has an adjustable rev-limiter and it all fits under the cap. Less to get wet when you get hosed down! I believe the HEI is inductive and so is the Pertronics? Correct me if I'm incorrect..........

The rules for the SE class are stock GM points or HEI ignition. You can have a aftermarket module, and coil in the HEI, but it has to look stock. Basically the same rule as the SS.

I had too many Mallory dual points come apart to ever use another one.

Carl, I have a couple of GM point type distributors if you need one.. I also have a remote coil HEI..(small cap)... I seem to remember there were GM dual point distributors back in the 60s..Wonder if there are any of them still around.....

Yeah Ray, GM sold a few MILLION cars with dual points dizzys. There are FEW around Probably because nobody but a restorer wants one.

As far as "reliability"...12 years my Mallory Dual Point NEVER let me down...EVER!
Set it once a year and it was good to go.

Two years ago I installed a MSD RTR dizzy, but the Mallory is on my boat ready to drop in > when the MSD fails.
My MSD has a looooog way to go before it earns the reliability my Mallory has.

When properly set-up > and there is a 'proper' way to set them up they work just fine.

My $$$ MSD really added NOTHING performance wise, vs the Mallory Dual Point it replaced. Idles the same, plugs are no cleaner. The dual point makes for a little longer duration spark. I believe the MSD-RTR makes multiple sparks before a certain rpm.

Note > not all Mallory Dual points can use a drop-in module > my Mallory YL couldn't.

carl, I have a good factory electronic ignition that came off a boat I recently purchased. It has the external coil deal. It's what they used after the big cap HEI. And guess what? It's free !!!!!!!!!!!!!!!!!!!!!!!
