first tnt leaves room for improvment

I have 2 Holley blue fuel pumps with hard lines(no kinks) to a junction block and 1/2 inch braided line to a basic Holley regulator with one line to carb and one line to nos fuel soliniod, line from regulator to carb is 3/8, i have a new starter coming, i will recheck the fuel pressure when i get her fired up again Dave. maybe larger jets ? The cam is 555-555 but with 1.6 rockers 587-608 should feed an 850 ? gonna try 12 psi in the slicks and see how many rpms the brakes will hold before see pushes for a better launch and pay more attention to the tach i was shifting by ear as i have always done with my street cars even though they have tachs. also going to adjust my basic b&m ratchet shifter for a smoother shift.
