I would say go with a bigger cam and bigger injectors, mass air

i want a better cam but not so much bigger, for drivability.
24lbs is good for na with that motor, 307hp. Running at 80%
But if i add even a small shot of nitrous i would need the 30lbs injector. So i believe 30lbs injectors is what i should get right?
Not sure what size fuel pump to get 190 or 255?
I do have a 76 mm granetelli mass air. It idles a bit rough w/19lbs injectors so i am not sure what injectors size it takes.

Don't dought the E cam sounds like a healthy 12sec car and a 255 pump will do the job.
Good Luck wit the car 👍

If you want to run nitrous with that setup I would suggest 30 or possible 36 depending on shot and 255 fuel pump should do the job

What Fuel pressure are you planning to running?? Can not pick injector flow without knowing that!!

Thank you i guess i overlooked that and have not done research on that yet, im on it.
But meanwhile do you think you can recommend a pressure. Im thinking streetable.
I do plan on gettng it tuned so it runs tip top

Well i run 65 LBS with 42LB units. To use the flow rating the pressure should be set @43.5 LBS But the tuner should steer you in the right direction!!

I would change the injectors to 24lbs. swap out the cold air for a powerpipe. Put a 255lph in it and spray 100shot minumum. Will run mid to low 12's on motor low 11s on the 100 shot with slicks. By the way nitrous has nothing to do with injector sizing if you run a wet shot. Looks like a good budget build. Good luck with your build
