bogging on take off

[331mustang]

went out today for the first time this year.new susp,tires wheels axles spool.everything ran out great.leaving the line i tried launching at 3000,4000,and 5000.didn't make any difference.when i leave it leaves hard then on the video you can see the nose drop back down just a little then pick back up.it's like it's bogging a little.was wondering if i should maybe change gears.i have 3.73's and was wondering if switching to 4.10's would help any.i'm running a a manual tranny and 275-60-15 m/t dr.as of right now my best is a 12.261 at 111.26 with a 1.721 60ft.

whats the condition of your clutch? I know mine is pretty loose (old+stock+abused from learning), so i bog on every take off unless i rev it or release the clutch with a even amount of gas.

the clutch was in the car when i got it.it was supposibly pretty new when i got it but you know how that goes.i got about 12 runs on it at the track and about 300 miles street time.it's a ram hd clutch.
