Default LS2 carb fuel system

Hi I'm wondering what the most cost effective/best working way to set up my fuel system on a 72 el camino

I'm looking for a 700 HP system that doesn't cost an arm and a leg but still functions right. I'm trying to keep costs down as everything costs an arm and a leg.

I'm doing a carb setup to start as I found a fully rebuilt LQ9 short block with ported 243 heads and LS6 cam and want the option to do and EFI swap later or run nitrous.

I don't weld so I'm in a tough spot as far as labor to upfront cost goes. I can't justify a ricks tank. Would like to keep my stock tank or use a tanks inc. one maybe.

Just want to do it right the first time so as I upgrade I'm already set and hate doing things twice

Since you don't want to do things twice, you might as well run EFI. The cost between to two is about the same in the end.

Bought a rebuilt LQ9 with a carburated intake. Came with enough stuff on it I couldn't get build it that cheap otherwise I'd agree. But that's not an option right now

A well tuned carb setup will rival a EFI in drivability. A carb setup would be easier to do on your vehicle with less hassle to get the swap up and running.

You could do a carb only set up for that fairly cheap. Summit racing brand external pump, stock lines if possible or plastic OEM style lines, couple of filters and reuse the stock tank pick up.

If you want something that will also support EFI the you need to think more on the lines of an internal pump and sump of some sort. Tanks Inc has some good info about there systems with carb motors. Gonna be some bucks up front but probably cheaper than doing it twice.

Cheapest way to sump a tank is drill 3 holes in the bottom of the tank than weld a cigarette pack sized sump on the bottom of that. Hook a fitting into the weld on sump and you can run an external carb or EFI pump. Shouldn't cost much to get that done if you do the labor of dropping and cleaning out the tank. Any good radiator shop can do the weld or even soldering.
