New hemi install total cost

I've been at this for a few years tossing around the idea of a 408 magnum based stroker or a stock G3 HEMI swap
The costs now are in favor of the G3 swap because it will cost $1,500 just in labor/machine work to have my 408 shortblock built.
tanked/magnafluxed
bored/honed with plates
align hone
square/zero decked
rotating assembly balanced (not including mallory)
assemble everything to be ready to plop on heads

heads I'm looking at some basic EQ off the shelf that's another $1,000
gaskets and stuff $250
I already have the stroker crank and new rods but that kit is about $1,250

We're up to $4k already I'd say $5k all in for a simple 408 build



G3 Swap:
ENGINE:
i'd need the engine $1,500 to $2,000 for a 2013+
I had a line from craigslist for a 2014 with 14k miles out of a 4x4 Ram that still had tranny attached
could have sold the tranny for $500 and only been in the engine for $1,500
Total: $1500

Tranny:
I already have a 46rh to back it I picked that up for $200
But I need a ATI flexplate to go with it so that's another $150
(ATI Flexplates
HEMI - Gen III to 904/727 Trans 5.7L & 6.1L
P/N: 915685
$142.00
)
Total: $500


Computer/EFI controls:
but then I'd need wiring harness $1k from Hotwire
Drive by wire pedal $200 (guesstimate)
computer flashed: $500 but could be $200 or $700, I just took an average
Total: $1750

Fuel system:
Carter 4600HP $115
BC Bronco's fuel accumulator - $70
Walbro GSL392 $110
Wix. 33737 - $40
Fittings, etc - $100
Cheapest EFI fuel system that will handle 600 hp is $435

Exhaust:
You may NEED headers and I think those go for $700
I hope to get away with Jeep SRT8 manifolds for $75
Motor mounts $200
Trans crossmember $150
Total: $500


Grand total: $4,685


I'm sure I'm missing stuff so you can add 20% to that so $5,600
or I'm also inflating stuff in certain areas and if you shopped around longer you could get stuff cheaper (for example that Walbro fuelpump can be had on ebay for $50 if you wait around) so you can cut 20% out of this so say $3,500

that's the range
