Average cost on ls conversion
Most Swap are like $2500-$5000, with better swap parts and newer accessiors and parts as neeedd (Fuel pumps, Lines, wiring, etc).
With new engines, more Performance mod's and Shinny Blink stuff. start with $5000+ and it goes too ????
But that all depends on what you start wtih. The budge one are usually are 4.8 or 5.3 for line $500+ for the pull outs.. and only adding what you have to.
Other pull outs, 6.0L (LQ4/9) usually go from $800 to $2000, Aluminun 5.3 (L33) or 5.7 (LS1/6) $1500 - $2500, and the newer 6.0 and 6.2.. well. it just goes up from there !
If I did it again I could probably do a 5.3L/auto swap for less than 2k.
I think that the single biggest thing I could have done to keep cost down would be to not be in a hurry. Taking time to collect parts on the cheap (ebay, swap meets, etc) would have helped me a lot.
The Best V8 Stories One Small Block at Time
Fuel system, regulator, fittings, headers, guages.

So you see its the small things that nickel and dime you to death. In retrospect I should have went with a used pullout rather than going with everything new. I MAYBE could have saved 40-50%
who knows but I would say at least in the neighborhood of 8k(deending on which motor and mods you plan to do) unless you are very mechnically inclined and have plenty of time and tools. Good luck with whatever you decide

The good stuff will have to wait, plans for it are adjustable upper control arms from spc and lower control arms from them as well, big brake set up front and rear, better coil overs, bigger sway bars, sub frame connectors, and torque arm suspension from BMR.
After that, IDK, but we will see as these type of cars are never done. This will take some time, but I plan on keeping the car for as long as I can. Intake:$275

I suspect if people really did an accurate accounting, they would find they spent more than they thought.

To be honest, I started to track money but realized that I really didn't want to know what the final cost was going to be. I save money on used parts when it makes sense, I do my own work, and I pay as I go. On the other hand progress is slow, and my quality doesn't hold a candle to Nelson or Trepanier. But I am OK with that. I know my twin turbo 408 will top 10K before all is said and done...

But this looks to be the reasonable way of looking at it. If I was doing it, I'd go this route (as much new) for piece of mind.
and TH400
My spend detail is quite high for my project. The car is will be a fair-weather daily driver- not a race car. Lowest possible cost was not my goal, nor did I want a hacked-up finish. Had I loosened my constraints I could have saved a few bucks, but I wanted:
- no-cut installation
- retain factory gauges
- Air conditioning
- maximum use of OEM parts
- emphasis on safety and reliability
- no investment of go-fast parts
- purchase 'guaranteed good' donor engine from reputable seller
- minimize parts scrounging
So, for my '84 Monte SS with '01 5.7L LS1/4L60e swap I bought:
$3200 LS1/4L60e drop out (radiator to driveshaft) from Cleveland Pick-A-Part
$375? RetroLSX Oil Pan
$200 Kwik AC bracket
$175 Sanden AC pump
$25 drive belt
$500 BRP mid-length conversion headers
$75 Spohn motor mounts
$20 OEM radiator nipple mod
$20 Cutlass radiator bracket
$60 misc Silicone Intakes hardware
$400 Shiftworks tail housing
$120 trans x-member (used)
$300 Borgeson steering shaft
$320 custom drive shaft
$325 Wait4Me harness mod and ECU flash
$500 electrical fabrication
$250 Buick GN fuel tank, pump, sender
$40 'vette filter/regulator
$150 fuel lines and fittings
$50 upper and lower radiator hoses
$50 misc fluids, filters, etc
$20 for '84 coolant temp sensor (got it machine for free! lol)
$50 trans lines to cooler (re-used cooler)
$90 Current Performance fuse box
$150 mufflers
$150 battery
$130 for F-body shifter asy (used) and shift cable (new)
Last big-ticket item is exhaust system fabrication. I have a couple minor brackets to build but material cost is free. Except for the electrical bits I did all the swap work myself. I'm almost home-free. The car is alive, so at least my build spending is almost finished. . . until that itch for go-fast parts really kicks in.
