ok so im doing a complete motor rebuild ls1 but head cam swap and other goodies... anyways im going to replace the fuel pump and injectors as well... i have a 99 camaro z28. so i believe the stock injectors are 24 and 2000-02 are 26. will my stock injectors hold up to 430ish whp while i break in the motor and clutch or should i go ahead and get the 42#s and i guess trailor my car to a shop to get a base tune on it... i would like to just keep the stock in until its time to to the dyno tune and swap them out that day

Find some 30# svo injectors, they're 36 at LS fuel pressure. Or do what I did, buy a brand new set from a sponsor. I have 37# injectors and they support my 430 hp H/C/I car just fine. You can take just the PCM to the shop and they can load a base tune on it for the injectors, however its intended to start the car so you can check it out, not really meant for driving.

I will add, the stockers will get you there as long as you're not heavy on the throttle. Light cruising will be fine.

Well wet shot doesn't require the injectors to provide any extra fuel, so if you go that route all you need is enough injector to feed the motor.
