I'm looking to get a MSD igniton for my 2001 1500 Ram, I need to know if the truck is even or odd fire. Thanks

You have to tell us what engine you have first.
Make sure the Mod you are looking at is actually compatible with the Engine Controller and not just something that will fit on your engine. You will have a CEL in no time if the part isn't made specificaly to be used with the factory ECU.

Oh my bad thought i had put that in, its a 5.9L, I was looking to get the MSD 6A ignittion, i'm pretty sure it works with any thin as long as its wired up right.

There's a 5.9 gas and 5.9 diesel eh.

Its gas

The 5.9l gas is even fire. Most engines are even fire. Some V6's are odd fire. They are called "odd fire" because the ignition cyles are not evenly spaced.
A even fire v6 would have an igniton every 120 degrees. An odd fire v6 would possible fire alternating 90,150,90,150 etc. . Depending on the deisgn the split may not be that pronounced but I'm sure you understand the point.
For the most part, a v6 with the "V" of 90 degrees is usually odd fire. A v6 with a "V" of 60 degrees is even. I think that the Dodge V10 is actually an odd fire engine. Anyone with a yes or no on that one? To be even fire (without splitting the crank) a V10 would need a "V" of 72 degrees, not the 90 that the Dodge has.
