I've got that same motor, with a tko600, and a 3.50 9" rear gear, and I've got a few suggestions for you.
First, put the shift-light right in the middle of your line of site somehow. You will NOT want to take your eyes off of what's in front of you if your stomping on the go-fast pedal.
Second, the first gear shift light will come real quick, so wherever you set the rev limit, start with a shift point well south of that to start with, and move it up from there.
Third, good luck getting thru second gear without lifting!
