Mamo power Guys I need some answers from those of you who are making big n/a power.
Car is a 70 chevelle. It's a new build, with a 500 horse ls2 with an ls3 top end. I have a Walbro 255 in a Tanks, Inc. tank, with all -6 fuel line. Corvette regulator in front of tank, and single line up to fuel rail. Car runs great, with no problems.
I'm almost done with a Mamo 434" n/a engine that will put down 625ish to the ground. It's likely a 700ish crank horse engine...maybe better. Why am I changing engines? Horsepower is a drug...
Anyway, will a Walbro 450 pump fit in my tank? I can't find any information on the physical size of the pump.
Should I upgrade to -8 line?
Tony has supplied 52lb. Injectors with the top end.
Thanks guys!

I'll re-phase my question...what are the differences in size, between my existing 255 and the 450 I'm needing?
It looks like the 450 might be a few mm's smaller in diameter, on the main body?
Am I looking at this correctly?
Bueller...bueller....

I can't personally give you any advice but I am also starting to build a fuel system for around 450ish whp LS 6.0 and would like any more info you have on your current setup. I have heard the Tanks inc tank with the Aeromotive 340 pump has been issues for people with hesitations and other issues

I love my setup. Never hiccuped or sputtered with just over 1500 miles on the build. The tank fits well, and is baffled for low fuel/sloshing spirited driving.
I could have spent over double the money, and went with a custom tank with multiple fuel pickups, but I wasn't planning on road racing, or even auto crossing with low fuel. Personally, I don't like the look of the custom tanks...they hang down way too low, and look funny to me. I have run the thing down to almost empty, with no issues.
The pump is a little loud, but I like it that way. It's easy for me to hear at startup, for priming purposes. So far, so good for me.
