Alright, so I wanted to break this down and see what it would cost to replicate this project. So here is the list of parts and prices that I came up with:
Autolite Spark Plugs AL-104 US $12.00
XPZ Cam Package COMP-XPZ 04-01-01338 with pushrods US $479.99
Valve Spring Retainers 04-01-01157 Modified steel US $44.99
Crow Cams Valve Springs CROW-4918-12 105 lb US $109.99
Siemens Deka 60# Injectors 09-50-001100 Standard EV1 US $249.99
Northstar Throttle Body Kit ZZ-NSTBK-5-MAF Used LQ4 MAF US $299.99
ZZP Subtotal US $1,196.95
Headers and Exhaust Work $200
Supercharger $1500
Adapter Plate $300
Tuning $100
Racetronix Fuel Pump $210
Grand Total : $3510
Now that is a lot in my opinion to get 350whp from stock. Granted some of those parts can be picked up used for cheaper. But if the point of the swap is reliability, then you don't want to go too cheap and too used. Not to mention I listed the TVS SC at $1500, which is way under new price just to please the masses. I didn't include any of the little stuff either, which we all knows adds up quickly. Like his alternator relocation, gaskets, fluids, bolts, etc, etc, etc. Right there you could probably add on another $500 easy. And a one time base tune for $100 that you can't really do any changes. Anyone looking to make the 375whp mark would probably want to get a tuner and do it themselves since E85 octane levels seem to vary so much.
Overall, I think that is an honest look at what it would take cost wise to do this swap on a stock L67 engine (not L32 like the OP), and have it reliable.
