69 valiant 273 suggestions

Dartfever I'm very interested to here what numbers you come up with
for horse power and 1/4 mile
I have a 273 60 over, stock compression, stock heads, 509 purple shaft solid cam
holley 650 vac., 904 trans low 1st gear,2500 stall, 8 3/4 391's

I haven't been to the track yet and was woundering what to expect
I was hoping for mid 14's or better
