How does one calculate cost efficiency? Is it based on just sticking with what you have, and dealing with the compromises of archaic technology, or having to fiind someone who knows how to tune your carb, because you lack the skill and desire to learn it? Is it sticking with the familiar and not wanting to change with the times?

First of all I probably know more about fuel injection, C3 computer controlled carbs, and conventional carbs than you'll ever know. Look in my signature, my daily driver is an LS2 05 GTO. I have over 40 years twisting wrenches for a living, I have no bias against late model fuel injected engines. Still a early muscle car IMO, should be true to the powerplant that came in it, you want fuel injection, retrofit it.

I agree that the swap is costly to do initially (it's a hobby, so a money pit, not an investment therein) but the gains are excellent and the potential is greater than any old poncho...if you want drivability and excessive performance. (Not quite possible to have both with a carb...said not quite)
I like the idea of setting and forgetting, not twiddling and hum-hawing whether it's too cold or hot...and this is on a stack car, not some, heavy cammed, flat tappet beast belching out ungodly amounts of torque while rendering 8mpg while cruising.
I think it's an excuse to not do it (swap), under the guise that it's too unfamiliar, too new and just plain wrong...lol.

I've done many engine swaps in my lifetime, I'm fully aware of what it takes to put something in a chassis it was never intended to be in. If anyone has a bias against something it is you that believes that a carb cannot be a reliable fuel metering device that will start and run well in any ambient temperature. If you have the tools and knowledge it can be done along with realistic fuel mileage figures. The cylinder heads are the gap between an LS engine and a Stratostreak engine and the ability of the ECM to manage the fuel and spark controls. The same technology can be applied to a Stratosteak engine, the heads is where they fall short.

Seriously though, I have always considered a carb, a controlled fuel leak and see no reason to not embrace the vast improvements an ls motor provides, ie. superior fuel economy, heads that flow for days in stock form (God helps us when they are ported) a car that you can plug up and it can tell you what ails it, with a plug-in and a few clicks.
Carbs be damned, fight what you fear, learn what's new...and who knows, you may actually like stepping out of th cave to embrace the electron and silicon age

You surely have made a bad guess of what I'm about, because your so far off base you might as well be in a different country.

A controlled fuel leak, obviously you don't know your way around a carburetor.

Not trying to sway anyone just dolling out my like everyone else.
Pulled out the original '68 350 in my Lemans and gave it to the junkyard for a nice little 5.3/4l60e conversion. Wit my C10 yanked out the sbc and tossed in a 6.0 but stuck with the TH350 until I get the funds to buy a 4l80e.

Since you've singled me out I've responded, please don't think you know me or about my thoughts. Your post really shows what you think you know about me, but you couldn't be further from the truth.
