The stock springs can't take the lift of that cam. Are you planning on porting the heads? The stock heads can't flow enough to do that cam justice. If your not porting the heads you would be better off with a CC305.

The stock injectors will be fine with the cam you plan, you will need to have the ECU reprogramed for the cam. Once you port the heads I would go with 36 lb injectors.
Wow 36# injectors with ported heads and cam? I thought the 30#ers would be fine...

buy a AFPR and set it at 58psi with your stock injectors, and have the injector constant programmed at 30lb.
trick the engine into thinking it has bigger injectors....
bryan at pcmforless recommended this to me.
thats what i did anyway, it is good enough to trap 115mph....

jesse
Why would you want to overwork your stock injectors? I don't think that's too safe...

Those are stock LS1 injectors, which is a mild upgrade that wouldn't work in the scenario being discussed. After running a good heads/cam car with 80% duty cycle, 30# would be the minimum injectors that would fit the bill. With the dry nitrous, that number is even higher.
