l96 fueling needs Hi. I thought that selecting the fuel tank and pump combo would be easy, but it turns out that I am in over my head. I am doing a swap into my 74 nova. I thought all I had to do was buy a swap tank and the lines and I would be golden, but I was wrong. So I have some questions that maybe some of you could help me out with. I am keeping the engine pretty much stock (just a cam change), it will run around 500hp (little less) at the crank. I will mostly be using it for road tripping. I might on occasion put E85 in it.
So my questions:
Are the stock injectors okay or do I need bigger ones to keep up with the HP. Again I will not be racing.
I think I need a 340lph fuel pump.
Stock configuration is returnless, but the guys at holly were telling me to consider using a return style regulator. Which should I do?
Can I use the stock regulator from the engine?
Does anyone know how to find the ohm reading from the sending unit? I think it is 0-90, but I cannot find out for sure.

The stock engine does not use a regulator. I would consider using a tank that has a vaporwarx module installed with a ZL1 fuel pump bucket. You can probably keep the stock tank if you can fabricate (or look at Rick's tanks for a stamped tank option with the VW module. This will support your power goals. Are going with Holley EFI?

UGH. I thought I understood this, but I guess not. I thought that all EFI systems had to have a regulator of some kind. It looks like Rick does not have one for the 74, and I do not want to modify mine (gas tanks terrify me, I almost lost a brother trying to modify his). I wanted to buy a efi tank and put it in. I just don't know what kind of stuff I need. I think I need the special lines for e85, a regulator/filter, a pump around 340lph.
I am keeping the engine mostly stock. No holly efi. It was just be the stock system.

If you want to go simple, get a tank From Tanks Inc or Holley with one of their pumps already installed in the tank. Then use the tried and true Corvette regulator/filter, which will be mounted close to the rear of the car, with a short return to the tank, and provide 58psi at the rail.

Only use the Wix or AC Delco (which will likely be Wix). Wix #33737
Also make sure you use adapter fittings that screw on, not the kind with the plastic clips. But all this depends on the rest of your plumbing. I where you need flex, I like using PTFE lined hose and then use Nicopp for the hard line under the car.
Again, many options for plumbing.
