so you're saying from the timing cover surface of the block to the pulley mount surface of the damper?
i have one on a stand i can measure but look at this and measure what you have there, we can always use more info

other factors that could affect balancer height are your crank snout & timing sprocket, are you using a 351C crank & timning set or an aftermarket crank & SVO type timing set?
