total $3,881.34

There were several other costs not listed- fresh water pump, a serpentine tensioner/pulley assembly, another radiator when my trans cooler line threads came out, and so on... Of coure, there were also a few minor pieces-parts that I didn't use for whatever reason, and $270 worth of exhaust manifolds I can't friggin' get RID of. So an honest number would be... right at $4000 for a fresh engine, with all the tools to tune it myself, and dial it in as my knowledge grows.

Now, the problem is that there are a few special tools to make this work, that you simply can't do the job without....

engine stand (Advance Auto) 84.99
books (Amazon, free shipping) 39.74
Coil spring compresser 19.99
Piston ring compressor (special 6.2 item) 70.00
Engine Hoist (HF, Craigslist) 100.00

OTC 4681 Power Steering Pump/Alternator Remover/Installer Tool 37.26
12V 2A Power Supply Wall Plug Adapter 7.99
OBDLink MX 69.99
ECM pigtails 54.98
2 0411 PCMs 169.42
Cost of Tools 779.36

You can clearly save on some, borrow and beg on others, or (as I did) have to buy them outright. Again, YMMV.

All-in, from soup to nuts... about $5K, no BS.
