MSD 6AL ignition

Don't know that one system is better than the other. I own both systems. Have an MSD in a Corvette and a DUI in my Fish Nautique. They do the same thing. Depending upon your skill level, the DUI is easier to install and maintain - install the distributor and connect one 12-volt wire. The MSD system is a multi-component system: MSD-6 box, coil, and distributor. A couple of suggestions. The DUI system may take a few days to get - not always available for immediate delivery, so order ahead. The MSD components are frequent targets of Chinese knock-offs (fake), so buy from a reputable dealer like Summit or Jeg's and order all of the wiring and connectors at the same time.   Remember when you set your initial timing for your new system that LPG has higher octane (100-110) than gasoline/petrol. The initial timing and total advance will be in the range of 2 to 6 degrees more advanced than the instructions indicate.

Travel safe and I hope you have an enjoyable trip to the US.

Love my DUI unit.

You're also going to need some high quality wires and a fresh cap, and likely a new coil.

Also, I recommend a Long-snout coil like the Blaster 3.

Situation is such...

If the rotor is inbetween nodes on the cap when you turn the key to on,
I've witnessed an exposed arc that jumps from the primary stud to the secondary on the coil. This is with no contamination and premium wires. Serious situation under the engine box.

Would have been better you got the 6AM, because it doesn't send a pulse when turning the key to ON.

The MSD6 will jump a 3 inch arc in air, so one needs to be careful.

Really doesn't matter what pickup you have on the distributer, the wiring is the same. I use a pertronix point replacement module, but because the input impedance on the mSD is so high, very little current goes through the module and it doesn't burn out.

Oh, and you can gap your plugs about .070 with that setup.

You best take the cap off the dizzy and take a look what is under there, else its too ambiguous.

Too bad i missed your earlier inquiry , my regrets, Could have saved you some hassle

Yeah, the rev limiter is only most useful when your vehicle has a clutch, or are jumping out of the water.

Some here will confirm, but i suspect whichever lead from the igniter to the - side coil is, that now goes to the MSD. Likely the green.
Then power and ground to the igniter, Cannot source 12 power from the coil anymore .
The MSD puts almost 500V onto the primary.

Math says that engine won't frag below 5500 rpm, just won't happen. Engine will live for decades at 4800.

The blaster 2 doesn't have the extended snout, i am concerned about your combination.
