Add MSD box?
I have a MSD 6A box that I havn't tried to put on my truck yet. I have an msd coil on there already. I'm looking through the directions and now I'm wondering if it's more work than it's worth. Has anyone done this on thier truck before? Mainly, I'm worried about the tach still working. Thanks.

I know, I still have to get one yet.
Now, does anyone know a good place to tap into a switched power supply, and a good place to ground to? Hopefully without splicing into wires. I'll probably mount it near the washer bottle. It says go right to the battery, but obviously that isn't switched 12v, it's constant. And I don't really want to run the ground wire right to it.

why? the tfi was one of the best ignitions made. it has the correct voltage and current required to run that 5.0. i doubt you will see an improvement over the factory set up. plus why do you want to install a 30+ year analog design over the factory digital unit? if you are looking for power increase's the factory tfi is a bad place to start..

Thanks for the input.
I havn't really decided if I'm even going to put it on yet. Is the msd really an analog design? I don't think it would hurt the performance of the tfi any.
The truck always cranks a few times before it starts, I'm thinking a stronger ignition may make it start easier and maybe even get some better gas milage.
What do you think of Holley's HO/performance TFI ignition modules?

a whole lot better than any msd. the msd is a cd unit. it has not changed since its introduction in 1969. it was state of the art then, but like a 486 now. holley brags(aka crane ign) the big difference in analog and digital. the best aftermarket ign system i have used is the jacobs, but still on an tfi unit, i doubt you will find much of an improvement. i would take a closer look at condition of tune...

msd means multiple spark discharge. it sparks more than once giving you a better conbustion. if msd was not working then why do you think they are still sticking with the same old idea. because it works.

why? does it confuse you. this is for facts and not opinions. go to the pigpen to leave opinions. the tfi far suceeded the dura-fart units. they where clumpy large, and failure prone when fords less than perfect voltage regulators failed. the system was prone to connector failure, as well as corrosion.

why not convert to a digital multi spark unit? mallory did, crane-holley did, jacobs did. because they make about a 300% profit on the 6a unit. i had a friend that worked for them for 10 years in R&D. all he did was design plugs. that was the only change they made. besides jelly filling them, and calling them marine or nascar units..

you have the tfi mixed up they are the ones going out sice the modules are right on the distributor where heat ruins them. it was a bad design to start with. i have seen and experienced many a tfi failures. what does it matter how big the systems are if it works go with it.

first people need to stop blaming the modules. if you buy auto zone or checker, or even napa units, you are buying JUNK. go to ford. the factory units last well in excess of 150k. that is over the average life of a small car now adays. ford converted because they realized the dura spark was out dated, and unsuited to do what they wanted to do next. everyone in the auto electonic industry has converted to digital reference. msd is slowly falling down hill. the race industry has realized that they are 25 years behind, and you will see more cars on the track running jacobs, or crane-holley than msds on any given friday night. read dr jacobs book "a doctors guide to electronic ignition" and you will realize the fall of dura spark and msd systems. why go back a step when you can take two leaps forward? its like building a computer with a p4 and sticking 64k of memory in it. where is it going to get you? no where..
