2.3 second 60ft time!
get that around 2.0 and you'll take atleast a half second off your time. Probably more.
Theres something else wrong too, because my dad used to have basically the same car (95GT AOD-E) but it even had stock gears, 3.08's i believe. I took it to the track a few times, got like 2.2 60fts and cut 15.40's on very hot nights. The only "mod" was a K&N, hell the timing wasn't even touched.
something just isnt right, I'd do a compression check on it, and maybe even a dyno tune
good luck with it,
