Run new lines
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.
