36lb - 42lb should be fine. A Racetronix Fuel Pump Kit wouldn't hurt either.

Agree with getting a better pump setup like the Racetronix and 36-42 # SVO injectors.....42# would be my choice.

You can get away with 36 lb/hr @ 3 bar injectors and have a little room to grow or use a 42 lb/hr @ 3 bar injector with more room to grow. Here's the calculation:



Personally, I like the Bosch Design III 36 lb/hr @ 3 bar injectors for N/A 346 applications.

I agree, 36's will do you fine, 42's if you have a LOT planned in the future.

i would get 42#ers and then a 340 inline pump if you plan on making 600hp, the 255 racetronix pump from walbro will only carry you to about 550
