Heres my current tally
s/c kit-$1500(brand new)
Bassani L/T, X pipe, flowmaster catback(used) $500
190lph pump-$100
30lbers-$100
slicks-$150
Bov-$20
Total-$2370
Best et as of yet is 12.7@107, with a better rear end gear(2.73's own me) low 12's would easily be achieved, so I guess a ballpark figure to run lows 12's would be $2500 give or take a few hundred
