So whats this kind of swap cost to do???

I am installing a 5.7 engine and 545RFE transmission from an 05 truck in my 73 duster and trying to do it on a small budget.

Costs so far:
Engine, transmission, computer $2000 (e-bay)
Fuel Pump, Vapor Canister, and wiring $350 (salvage yard)
TTI Headers $780 (could have used grand cherokee manifolds to save money)
TTI motor mounts for 72 down k-frame $125 (they didn't have the spool ones yet when I was working on this)
Flaming River Manual steering gearbox $500 (could have found a slow ratio factory one for less)
Countless hours fabricating transmission mount and tunnel area. $???

Future estimated expenses:
Aftermarket gauges and dash panel $700
Computer programming $250 (hotwire) or $450+ (B&G Performance)
Miscellaneous Sensors $100
Radiator and fan $???
Countless hours creating custom wiring harness from factory harness $??? (hopefully less than the $1000 you can by one for)

I'm sure there will be other thing that I'm not thinking of but these are the big ones. My goal is to create a super reliable car that is easy to maintain and fast and fun to drive anywhere.
I was originally going to stroke a 360, but after I read the June 07 Hot Rod and other articles the allure of a modern engine and transmission was too much.
