2002 camaro. Putting 454 LS7 in it. Will factory fuel lines with walboro 340 be sufficient? Do I need to convert to return style?

How much power do you expect to make? The answer will help determine the fuel plumbing.

Curious as to how you're getting 454 out of an LS7? I thought 440 cid was the max with a 4.125 stroke? I have a 454 but went with a darton sleeved motor.

I'm running stock lines returnless and a 255lph which I already had in there. But if I was doing it ground up I'd go with a 340lph for extra breathing room. Not sure what it'll make, getting some tune issues sorted now so I can fully break it in before running it up on the dyno.

I was told it is 454. Perhaps it is a 440
