track times not to good

this was my best run.

r/t = .748
60ft = 2.180
330ft = 6.280
1/8 = 9.636
mph = 70.81
1000 = 12.537
1/4 = 14.975
mph = 92.49

whats up with that. i was at least expecting low 14's. i just bought a holley tbi, weiand carb intake with adaptor. so maybe that will help a little. its goin on next sunday and then ill be at the track,

Dude those times arent very good at all.Did you say you ran those times with the stock throttle body? because that would definetly restrict your engine and that could be the reason. With that setup you should easily be in the 13's.I just dont know what to tell you. Good Luck.

Might wanna think about a better fuel pump as well, especially before you start chip tuning.
