MSD ignition unit

[Alt-F4]

Hi,all.
I did a search here and online and didn't find any info so I will ask.

Has anyone installed a MSD ignition unit on the H2? If so did it help with low end torque? I have used them in many other trucks, and the system has always rocked. I'm not sure if it is compatible with the H2 6.0 vortec engine. I have use both the red 6a and green 6a off road unit w/ rev limiter in the past.

I'm still working on figuring out the list of mod's I am going to do in the next couple of months, any input would be great.

Thanks in advance for any and all replies.
