I got my LS1 and T56 for right at $3000, and I probably have another 2-3k in the swap itself. Compared to some of the really nice ones I've seen on here, that's fairly "economy".

INteresting thread, my son is doing a LS conversion on a '57 Chebby pickup and has a 4.8 LS engine already....I hope he goes automatic tranny for it....he in Berzerkly Ca. so it's a long way to be much help....
I know people will disagree, but I could do a low budget swap for less than $ 1,500. It would be a fairly high mile truck 4.8 or 5.3 with the late model 4 speed auto, self built motor mounts & wiring harness, exhaust manifolds, and a basic stock tune on the ECM. You could knock off $400 or $500 if you only did the engine and used an existing transmission. I have a little over $1,400 in my 5.3 with TR6060 six speed. My 70,000 mile engine is in great shape, and the trans is like new. After working out all the other changes to my C3, I may build a 6.0 to drop in. You could also buy a crate engine, stainless headers, fabricated motor mounts and wiring, have extensive tuning and have brand new equipment for much much more.

You can do it VERY low budget, depending on the amount of fabrication you can do yourself. The wiring harness, T56 crossmember, and hydraulic clutch setup alone cost me over a grand.

but going to point him to this thread....
Interesting, is your son in school at Berkeley? I'm asking because I'm at school up here as well.
It's pretty difficult to do a budget swap in a C3 for under $2500. You NEED things like the low profile inake/oil pan, low profile FEAD, electric fans, etc.
A lot of people "forget" about things like exhaust mods, fans/controllers, hoses, driveshaft/yoke, trans mods, CAI, specialty connectors/adapters, and the list goes on. Then there are the things you would be changing with any engine swap/rebuild, pretty much any rubber piece, clutch, etc. Then the cost of tools like NPT tap set to modify the water pump heater inlet/outlet or huge metric allen wrench fot the block plugs.
Then there are the "while I'm at its".
My 68 with a 6.0 LQ9, Richmond 6 speed, and Vintage Air was probably around $10k. But on my 72 442 with a 5.3 I was able to do it for around $2500 and reuse most of the truck stuff.
The cost will also depend on how much of the work you can do yourself. The only 2 things on my swap that were done by others were welding the offset shifter mount and welding up exhaust pipes between the headers and the crossmember. I did all of the other work myself with the help of my 2 sons.
There were several of us who were "early adopters" of the LS engine swap in a C3 and all of us made many contributions to the giant LS swap thread. That thread probably contains all of the infomation anyone would need to put a LS engine in a C3 with plenty of variations for wiring, fuel systems, etc.
There are a lot more commercial parts available now for swaps so the need for fabrication is reduced a bit but no 2 installs are the same.
You can do it on the cheap, but what you save on the front end, you pay on the back end. By that I mean sure you can score a high mileage 5.3, LQ4, LS1 cheap, used sensors, etc but sooner rather than later those things will need to be rebuilt or replaced. I'd rather do it right the first time, and not worry when a high mileage engine, trans, etc will fail.
There are so also hidden costs many are unaware about.

You are very correct, all true. And there are many hidden costs if you do not research before jumping in. If you pay someone else to do ALL the work, it could cost more than the value of your car. Here is another way to look at it. If I buy a used C5, all you said above applies, but I am limited in what I can inspect before purchase. The difference with the swap is: I saw/heard the engine run before buying, Had a chance to inspect it internally before installing. Used new fuel pump and O2s, and examined every part I installed. The used C5 could have just as many "maintenance" costs as the swap. I enjoy the challenge, I could easily buy a F body or C5 oil pan but chose to modify the truck pan. The cleaned up truck intake fits under my Daytona hood, but I could have easily bought (~$100) an LS1 intake from an upgrading Fbody driver. And yes my opinion is low dollar as well, it is worth every penny you paid for it.
Well mine got pretty expensive because nothing was left untouched, and I used very little from my original purchase.
$4500 LS2/4L70E drop out unit with 6800 miles.
$4200 to rebuild motor to a forged stroker 402 because the low mileage motor spune a rod bearing.
$3400 for the LS2 Trick Flow head and cam combo top end kit.
$1000 for odd and ends for the motor.
$4400 for a new stage 5 4L70E transmission that will withstand the 600+ HP form the LSX.
You guys can do the math and see that this build become very expensive but the end result is a 600 + HP car that will put a smile on my face every time I take it out.
To do this same build over again I believe I could do it for half this.

You ended up with a nice swap, and I am sure it is worth the time and money to you when you drive it.

And I was just getting ready to ask which one of you voted $15,000...
Yes, the best advice to save as much money as you can is research, research, research. You can make so many mistakes when you haven't done your research, but for the C3's there doesn't seem to be one set standard that is being followed and in some cases, work work for one doesn't work for the other.
I do have a lot invested in my LSx swap, but outside my original purchase of 4500 for the stock setup, I am glad I took it to the next level with all the high performance goodies that are in my setup. The car is a real adrenalin rush, its violent and sounds like war when you stand on the throttle.
There are also other cost that I didn't mention like the stainless headers and full stainless exhaust and much,much more.
Here is what it looks like at the moment and it not finished. This picture real doesn't do it any Justice
