H/C 346ci+150 wet shot,What injectors?

[SUPER_CHEVY]

Guys, I'm in the process of putting together my engine and just wondering if I would have to change the fuel injectors?

It is a stock bottom end full bolt-ons with "231/240 .643/.608 112+4" cam , PRC 5.3 heads "stg 2.5/sink valves to MS3 cam" and TNT F2 wet kit 100-150 shot. It would be mainly NA, the spray will be ready if needed.

What do you think?

If yes, what kind of injectors should I have?


Thanks in advance.

id go 42lbs that will give you what you need with some room to grow

42lb/hr would be recommended with the H/C setup alone. You stock injectors will not be ideal for that setup. The wet kit will provide its own fuel...so the 42s will be fine. Maybe add an intank Racetronix kit.....that way there will be no worries for future mods either.

Thanks for the fast response guys, but what brand should I buy?

Putting in consider the price/quality, because I'm on a tight budget? What do you think about the SVOs/SVT ?

svo's are great i went with lucas though got a good deal on them and for street racing they look like stockers they arent colored

I am running Fast 36lb injectors on my setup and only run at about 75% duty cycle at WOT.

[SUPER_CHEVY]

What is the expected duty cycle % to get for my setup with both 42 & 48?!

And what about 38lb injectors? Are they small for me?

anyone please!!

I'd go 42# aswell mine have taken me to 550 hp with a turbo. U should be good with 42's with a wet shot

I am running the FAST 36lbs. With your setup I would imagine that would be big enough. maybe step up to 42lbs.

you can never miss the chance of getting injectors that are far more superior then what you need. 60lbs would be great just incase you decide to up the spray or go FI
