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.

 

With the small cam intake and exhaust 600+

 

Define "small cam"....

 

238 /254 113+4 650/630

 

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

 

What's the bore and stroke?
