Stock injectors with cam

Can stock injectors be used with a cc502 cam?

Just wondering as I just ordered the cam and Ill order injectors in I need them, was gonna go with a 30 or 32 bosch injector

Do a google search on calculating fuel injector horsepower. There is an equation you can do.

I think you would be ok running stock injectors up to like 300 HP, but I have seen people who have dyno'd 400 HP and run on stock injectors with just an upgraded pump and regulator.

How much power do you think you will make with that cam?

You can run about 360HP at the flywheel on stock injectors, limiting the duty cycle to 85%. You should be OK with just a cam.

Stock fuel pressure regulator is good for big HP. Don't worry about it.
