E-85 on stock injectors and fuel system

Im currently putting together a freshly built 6.2l ls3 with a texas speed stage 3 cam and full bolt ons. I already know what the car is most likely going to make so i want to step it up. Is it possible to run e-85 on the stock injectors with a cam and full bolt ons?? Also the car has a zl1 fuel pump.

I recently converted to E85 and upgraded from a Zl1 pump with 65 lb injectors to a Fore twin pump system and 1050 lb injectors. The ZL1 pump and injectors would not deliver E85 from the tank to the motor.

I did pick up about 70 hp to the tires with the upgrade. I'm also FI, but I hear non FI cars upgrading to E85 don't pick up a lot of hp.

I maxed my bolt on cars injectors on E60 at 470ish swapped to LSA and had room to grow with them. Ended up making 475/473 with it.

I picked up 30 torque below peak and 12 horsepower. It is a significant change IMO

Yea, My tuner says that with my current setup i should pick up around 15-20whp the 93 price in my area is already high!!!!! Does anyone know what size injectors i should run? From what i hear the zl1s will be close to maxed out if not maxed out completely.

I'm heads and cam LS3 making roughly 600hp or better at the crank and my LSA injectors are maxed on E85. I have CTSV pumps.

Get the flexfuel injectors. Slightly bigger than LSA and cheaper.
