Fuel injector size question

I'm planning on building a stoker motor just haven't decided what size yet.

At this point I still have the stock LS1 in the car and will be adding the following mods:

FAST 92 with LS2 90mm TB
Headers with high flow cats
TSP Stage 2.5 heads
EG Whiplash cam

With the above as mentioned, what size injectors should I buy that will work properly and still have room to grow ?

Thanks for your input and help.

At least 36 42 would work too

Something like 44lb/hr injectors would work well, or you could step up to 60lb/hr injectors if more power is in your future plans.

For heads and cam 60's are overkill. If FI is in your future you'll probably need 80's anyway. Why buy a way more expensive injector if you don't need it.

Plenty of guys running 60lb/hr injectors on turbo and Procharged setups. Also, the 60's are no more expensive in the classified section than the 36-44's.
