Post 3 on that link says it all. Nothing wrong with what ever way you go, just depends on what your needs are. I have had EFI in my car since 2000 and don't miss the carb at all.

if you dont mind tweaking your carb for temp and altitude go with the carb. efi just tweaks if for you. pretty much all there is too it

If you had the option to go FI, why not? There is nothing nicer than having your car start-up and run like a modern car.

I don't recall the last time I flooded my car, died under hard breaking, or complained about the crisp throttle response. ;)

Don't go carb unless you have a legitimate reason.

A well tuned carb can be very drive-able and reliable. I have found since going back to a carb, I don't like the pedal feel of getting into the secondaries. The power is difficult to modulate once you get into them, kinda like an on-off switch.

No matter how well tuned a carb is, you won't be able to reach through the window and start it! (even cold!!!!)

I just got my LS3 project done, EFI. The only way I'm ever going to use a carb again is if the car is original and came with it. No way I would use a carb on one of these.

Just my 2 cents.

Thank You for the help guys !

Another question:
For swapping my LT1 to a LS3 what I have to change ?
I think motor mounts and headers, about the clutch I can reuse the same ?
I have a Tremec T56 six speed installed on my car

I have a Tremec T56 six speed installed on my car if it's a lt1 t56 your going to have to change the faceplate and input shaft to a ls style and I don't believe the clutch will work
