After looking at your changes again, with the head
work and bigger valves.... I think you will run a
10.4 at 128...... if you can max out the package.
But its hard to say if your engine was near max to
give you the currant 124 mph(if you were FAT or LEAN)
you werent max HP, you made enough HP to run 124,
see what I mean
