Yup, not enough gear for starters.

IMO, unless the motor is at least an honest 13.5:1cr, both the comp .690 and .692 rollers have too much duration for that combo.
And even at 13.5:1, I think for 1/8 mile racing especially, something shorter would be quicker.

The other thought I had was to try and verify you're getting a good clean release in the trans when you let go of the button.
If the 60' times are about the same when footbraking it, that would tell you the brake is releasing fully.
