so I got this kit for a 5.0 it is a bunch of different miscellaneous components. Zex 10lb bottle, edelbrock fuel and nitrous solenoids, and an edelbrock series 2 nozzle. I'm putting it on my bbf 429. I will be retaining all of the 5.0 factory fuel injection. I have coast high performance EFI Spider plenum and fuel rails. With a C&L mass air. The motor is a:

1969 460 block
Steel 429 crank
440 dodge rods
Custom 13:1 forged pistons
Cam specs: dur@.50 I.272 E.282 Valve lift.665 Lobe sep.110 Solid Lifter
Ported DOVE heads
Stealth duel plane manifold

What i need to know is if the nozzle that i have is going to work, and, the jets that i have right now are .026 and 120, what does that mean?
