Tach does not work correctly after 8.1L swap

i believe these motors use a 4cyl tach setting....(atleast when adding an aftermarket tach) Not sure if that'll help at all...

Yeah, that is what I read. I have a SunPro mini tach but it doesn’t have any switches that I can find to adjust it to a 4 cyl mode. If it did that would save me a big hassle.

Actually, I am not impressed with the way the MSD kit interrupts a coil signal. That just makes me nervous so I would much rather swap a tach than hack open a perfectly good coil harness and cut into it.

If anybody has any tach recommendations I am certainly open to that. BTW, I called SunPro and they wanted to sell me an adapter that is even more hocky than the MSD dealeo.
