Default Walbro 255

Hey everyone. I have a 383 LT1 that I am eventualy going to supercharge. I am taking the engine out of my 92 and putting it into a 95. Is the Walbro 255 enough for a supercharged 383? I have an Aeromotive 11106 but don't want to cut into the cars fuel system like I did on the 92. If the Walbro 255 is good enough then I will put one of those in the tank and not mess with the cars fuel piping.
Thanks
Pete

It should be good enough. The stock fuel lines can support alot of hp from what i have read on ls1tech, If it ever becomes a problem you can always do a dual walbro setup and even have one kick on at a spasific boost.

my walbro feeds a 383 and a 200 shot.... runs mid 10's... I am gonna get a A/F sensor and throw on da 250 and see how she does.

My 255 pump, stock lines and rails supported a 175 shot Saturday with no problems. (My standalone was leaking.)

Cool. I figured it was good. I would rather put the pump in the tank and not have to worry about it. I like the Aeromotive, but it is prety loud.
