Fuel System Help (64 Impala)

I'm in the process of gathering parts for an LS swap into my father's 64 Impala. Right now i'm trying to plan out a fuel system that I can do right the first time and will be adequate for modifications down the road. Car will be getting either a 4.8 or 5.3 depending on which one I find for a decent price first. As of right now the plan is to get it up and running before making any real power just so I can iron out any wrinkles as I go...In the future the car will see a turbo system and the hopes of 600-700 to the wheels.

So right now the system is completely stock and I'm having a hard time deciding the best route. I'm considering a modified tank ready for fuel injection like this:

Then I can run an in-tank pump such as the Walbro 450:

What are your opinions on a set-up like the one mentioned above? Am I spending too much and I should just sump my stock tank to run an in-line pump? I'd have to pay to have this done and I'm not sure that I'd be saving much in the long run. Let me know your similar experiences.

I would suggest walking the junkyards with a tape measure and trying to find a late model car with a fuel tank that you could use. You'll probably come away cheaper and should be able to get the tank and pump together.

I actually considered that option also but who knows how long that could take to find a compatible match...I may end up trying it however.

Tanks inc stuff is great for retro swaps. I have a complete kit available to finish off the install with their tank. Clean and simple will make 600whp with Walbro 255 even more with different pump. http://www.nastyperformance.com/shop/nasty-performance-universal-lsx-conversion-fuel-line-kit/ I can also get that tank for you. Let me know if you have any questions.

Knowing 58 - 64 Impalas fairly well and having been under more random vehicles than I care to admit or count in the salvage yards, you are time and money ahead with the Tanks Inc setup.

You aren't going to find a factory fuel injection tank that fits your car without heavy modification to the car, tank or both.
A factory fuel pump is not going to do much beyond factory power levels.

Which raises the question why waste time trying to modify a 40 or 50 year old tank when someone sells a new one ready for what you need for less than it would cost (in time and effort) to modify the original?

You would better off buying a pump from Nasty N8 than getting one off of ebay. The bulk of the pumps sold on ebay are not real Walbro pumps. They are Chinese knock offs and will fail within a few months. Usually two or three months can be the life expectancy of them.

I bought a new $200 RCI 15 gal aluminum fuel cell with fuel gauge sending unit from Summit
Then for around $300 you can buy the new ultra quiet holley 12-1800 twin pump and mount it external, (Or internal)

You could also just get the 12-1400 pump.

I also bought some rubber fuel pump isolators from race part solutions
