My problem seems to have been resolved with the new ground location.

Tony where did you ground your MSD?--I have a 6al, MSD distributor, a Blaster coil--a SW tach that is erratic--it rarely "zeroes" after shutdown, works ok just cruising but when I put my foot into it, it will jump to 7K rpm +/- , I know the engine isn't turning over that fast . I thouht I had a good ground but now your post has made me rethink.
