Thats what I'm talkin about.
Here are some more specs i found on this engine. the price on a long block for the 620 hp is $10.600 less carb, distributor, water pump,and intake.the price is getting better. GM聮s most powerful. The ZZ572/620 is built around an all-new Gen VI tall deck race block, filled with a forged, 4340 steel, 4.375聰 stroke crankshaft, shot-peened rods, and forged aluminum pistons. The newly redesigned rectangular port aluminum cylinder heads result in a pump gas friendly 9.6:1 compression ratio. Also included is a .632聰 lift, hydraulic roller camshaft, roller rockers, dual valve springs, 620hp and 650 ft. lbs. of torque! ZZ572 / 620 Technical Information 路HP: 620 @ 5500 RPM 路Torque: 650 Ft.

Thats what I'm talkin about.
That is a nice motor, and I love GM parts, but they charge so much for there completed engines. A better engine could be built for less. If someone wanted to finish that engine right, you would be looking at a rough estimate of Engine cost+:
Complete EFI(inc distributor, ECU, ect...) $4000.00
Fuel pump, hoses, ect........................... $550.00
Exhaust with tails(cmi, powerflow plus.) $2500.00
Accessories( brackets, pumps, bolts.....) $2000.00
Oil Pan, oil cooler, ps cooler, lines $1500.00
Bellhousing,coupler $550.00
Motor mounts $300.00
Crossover, h20 hoses, clamps $250.00
misc sending units, silicone, sealer, ect......$200.00
Total $11850.00 (No labor)
Now all you would need is to change that cam to a "marine" application$300.00) and someone to map your computer:$500.00(roughly)
New total $12650.00 Not including taxes, shipping charges, labor, phone bills, gasoline expenses, ect............................................... ...........................
Now everyone knows you could lower the price significantly by putting a carburator on this motor. But the future is EFI, and that would make this motor worth all of that $$$ you are investing. This list applies ONLY to stern drives. Jets and v-drives could build this motor for a hell of a lot less IMO. It is unbelievable how much this stuff adds up to when you break it all down. This is a "ROUGH" estimate, because everyone has a friend that can get them a deal. Hopefully, This list might help as a guide for someone that was thinking about building there own performance powerplant Good Luck.
All you need to do after buying that engine is take it over to Westec Dyno and they will extract 800 HP by bolting it into their dyno!!!!
still this is cheaper than buying a 28k plus custom engine.around 23k is not bad to have a 620hp engine.

I totally agree. $28K for 620HP would be outragous.
I think Info can build a bigger badder for less. GM stuff is cool but as stated $$$$
