I'm not a fan of the SV intakes unless you are spinning some big RPM. IMO, 6K on a 400-420 incher is not big RPM.
The car is a little weak in 60'. The front end of your car plays a bigger part in how it leaves than the rear. the converter is a huge part both here and the big end.
I don't know what you have for fuel lines, but, that will play a big role here as well.
If you chopped at 1000', take about .15-.2 off the time and add maybe 3-4 mph to your numbers as that's likely where it would have run.
IMO, that set up should run above 120mph in the 1/4, closer to 122 minimum. It should have a bunch more in it.
