how much more performance?

[HiFlow5 0]

i'm looking into buying a 87 notch 5 speed that i just found. it already has a auburn diff with 3.73's, sub frames, ram air, and weld drag lites.

if i get it, swap my motor into it and convert to mass air, how much more can i expect out of it compaired to my auto GT.

i ran a 14.9 at 95mph with the GT (which i wasen't happy with), what do u think the notch will run for times after the swap?
