    I just got my 5.3 block and parts back from the machine shop and about to start assembly. Cam should be here tomorrow, oil pan Saturday. Heads are getting freshened up and should be back in a few weeks. Im trying to decide weather to go full ls with the fuel injection or do a carb swap. I know nothing about the ls wiring and computers. I will be running the 350 turbo in the elco so from what Im reading I need a standalone harness for non elec trans and a fuse block. As far as ecm, don't have that yet. Not to mention fuel pump and tank. I have Always had carbs so all this has me leaning towards a carb swap. I welcome input from both sides to help my decision.

    Efi is worth the trouble on the front end of the project for the lack of trouble, efficiency, and consistency after it's done.

    My $.02- carbs and non-OD trans LS swaps baffle me. Why not just do a healthy 406 or 383 that'll have the same power and bolt right in? No special oil pans, motor mounts, headers, distributor drives, etc.
    I don't get it.....

    EFI is really tough to beat. The only carb advantage would be immediate simplicity. You'll give up power, MPG, cold start, and reliability.

    Only you can answer your question - old school or the way of the future. Looks like money will be your deciding factor

    I'll say this, I just got my car completely finished with an LS1 and a 700r and love it. I bought my harness ($450) because the one that came with my engine was hacked up and could not be used. If you get on LT1swap.com he has all the info you need to do the harness work yourself or you can get it don't by someone in the $250 range. If you're going to put the time and effort into the swap I would get the benefit of the injection as well.

    Just my .02

    :rofl: not one of us suggested "old school" (carb). What just happened here? Why even ask?
