Default Not sure what injector size I will need for my build.

I'm in the process of rebuilding a stock bottom end LS1 with...
P&P heads
MS3 112 cam
I'm fairly new to LSx motors. My goal is to have a 420-450 whp DD. My questions are...
1) What size injectors will I need? I have ford red tops, but I'm not sure if they will be enough.
2) Will an LS2 single roller timing chain be good enough for my goal horsepower?
3) Probably a stupid question, but... Do I need a larger oil pan with having a ported ls6 oil pump? Just want to make sure that the pump won't cause oil starvation at higher rpm's.
Thanks in advance for the help.

36-40lb will keep the duty cycle around 80%. Fast 36lb is a good choice.
An ls2 chain will work just fine
The stock pan will also work just fine.

That's what I was hoping to hear. I sold my ford green tops and was hoping my 36 lbs would be enough. Thanks for the info, man.

Thanks for the info. Never too young/old to learn something new. I'm bookmarking that equation.
