It means you will have to go with a much taller tire and/or lower gears, to keep you from shifting into 5th with a 200 shot. I would think you should trap 133-135 mph.

i looked at the gear calculator and with a 28'' tire and 4.10 gears you should be able to hit 138mph at 6800rpms. Did you do the dyno with a 26'' tire?? if so then you should be okay with the 200 shot as i think you would be right around 135mph
