Bad 60 foot, tuning

thanks will look into the shocks.with less preload at the caltracks could it hook better?
The setup is a 512 12,2:1 640hp+ a 250 shot. power glide pro tree transbrake with 8 dynamic converter, 3,89 rear with spool, 28x10,5 , calvert monoleafs and shocks.
im no tuning expert and want to learn ...
the run above was at transbrake at 3000, 4500 is max
