how big of carb i can go on a 5.3

[64nailhead]

3310-1 Holley 780 cfm - double pumpers suck ash on the street. And the 3310 will not hurt at the strip on a small motor.

It's a trick question! 5.3s are fuel injected!!!

has for the fuel injection i had friends give me the parts and some i had to buy but the next motor i will run fuel injection with a turbo and nos trying to build a stoker motor or go back to a big block and my friend went from fuel injection to carb and picked up a few tenths

I have to say/point out, if you want to run a carb on an LS, then the best time to do it is with a turbski. No need for an intercooler with a blowthrough carb on C16 or E85.

If your serious contact one of the good carb builders to build you a carb. They will take all your build info and make a carb that will be bolt on and go. APD has built my last 3 carbs and they were perfect right out of the box.
