Are Frame-mounted fuel pumps OK for a DD (1957 Chevy Sedan)?
`I'm about to begin a LSx conversion for my '57 Chevy Sedan, which will be my daily driver when finished. I don't have the engine yet, but am about ready to start gathering the swap parts. I'm leaning towards BRP Hotrods for the swap motor/frame mounts, trans crossmember and headers. I'm not sure what to do about the radiator and fuel pump.
I'll most likely be running an aluminum 5.3, with a mild cam, unless I can find a screaming deal on a LS2 or LS3. For now, I'm planning to keep the drum brakes and manual steering, and that's why I'm interested in the aluminum block, to get a little weight off the front wheels.
For simplicity sake, I like the idea of a frame mounted pump, but have heard they do not survive in traffic. I will be returning to L.A. when I get out of the Army next year, so the pump will need to be able to deal with the LA traffic and hot weather.
During my research, I came across this tank set-up, but I have not been able to find anyone that is running it to get some feedback.

Any experience with the frame mounted pumps or this fuel tank set-up would be appreciated.

Yes.. for a DD I would go with a intank setup, less noise and service life would be longer for a Daily Driven car (granted some will say their external will last forever and has).
that tank seem to be a good price if it is correctly baffled. If that is a stainless tank, that is a plus. I wonder if this is the Spectra tanks ?
There are many new Cross flow Radiator setup for the 57, I would like into one of those. Being in the LA area.. traffic !! yuck.. you will want a good radiator and fan setup.
You going with AC ?? One of my buddy used the Mac's front runner setup and radiators in the past, worked well.

Mine is frame mounted, but I'm more concerned with an errant rock hitting the braided fuel line.
Pump noise is evident, not bothersome.
If the pump fails, it's easily replaceable.
To the comment below, AAA will get you home, whether the pump is in-tank, or external.

I've got a frame mounted on my 68 corvette and an intank on my 72 442. Given my choice, I would prefer intank with sump and baffles.
If you currently have a good tank, you might consider an intank using a sumped Tanks Inc pump or modified f body.

I had an external pump a long time ago and could not stand the noise at idle. This was with a loud exhaust. For cruising it was typically fine but the noise did make me get a tank built. If you have the choice go internal

For a DD, go internal. I have had an external pump fail twice and that was enough motivation to switch to an internal pump. For me an easy to change pump means nothing if I know that I will be left on the side of the road. The hard part is figuring out how to get home or knowing that it will fail at the worst possible time.

Thanks to everyone for the suggestions.
BC, I looked the Spectra tanks up on-line and it looks a lot like them. Might be the same. Do you know anything about the Spectra tanks... such as quality, what HP level it will support?
For now, I'm just planning to run an alternator and electric fans (no AC, PS, or PB), if I cannot make a truck fan and clutch clear using a 1" set back engine mount and the 6 cylinder radiator position.

The Rock Valley tanks look nice, but are a bit spendy.
Thanks again!

This tank as been the subject of many threads.. the earlier tanks were known to have fuel starvation issues.
Not sure if they have corrected the baffling or not... Anyone have any updates on these tanks now ?? any new updates on them or still the same ?
Here are a few threads that I found doing a quick search.:
