What I don't understand is that there are,

3 efi set ups with carb
????
I would like the efi set up with carb for the old Skool look,if it's possible?


Thanx for helping out

That would be an LS engine with a throttle body style injection instead of a port fuel. You can buy a LS 3 and use something like a FAST system on the engine. This looks similar to a carb, but is actually a throttle body and the injectors are under where the float bowls were located. I have also seen a port fuel style injection that uses a carb style throttle body just for the air intake. The injectors are still in the intake manifold mounted near where the intake bolts tot he head. This seems like it would be a lot of work just for looks, but if you are planning on using a Holley HP or Dominator style ECU, it is relatively easy to hook up. A lot of older style GM engines where EFI wasn't originally available use this style.

Lots of options. All will work reasonably well if set-up correctly. You may want to visit this site for more information.
