What would a S/C L76 cost? A thought just occured to me for a damn nice Forced Induction GM 6 Liter that could recieve high boost without major modifications.
http://media.gm.com/servlet/GatewayS...39&docid=21579
Designation: L76
Type: 6.0L OHV V-8
Displacement (cu in/ cc): 364 / 5967
Bore x stroke (in x mm): 4 x 3.62 / 101.6 x 92
Block material: cast aluminum
Cylinder head material: cast aluminum
Intake manifold: composite
Exhaust manifolds: cast iron
Compression ratio: 9.67:1
Valve lifters: hydraulic lash adjuster, roller finger follower
Horsepower (hp / kw): 355 / 264 @ 5400 rpm (est)
Torque (lb-ft / Nm): 365 / 504 @ 4400 rpm (est)
Crankshaft: nodular cast iron
Connecting rods: sinter-forged metal
Additional features: electronic throttle control, variable valve timing, Active Fuel Management technology, extended-life spark plugs, extended-life coolant, GM oil level sensor, extended-life accessory drive belt
Now Consider that this motor comes with the L92 heads on something similar to a LS2 short block it should make for a stout FI starting point.
You would need to do a couple of things to retro fit the motor into a F-body, Vette or Goat... or classic hotrod
Replace the Timing chain system with a LS2 system (including cover). This would removed the Cam Phaser (which handles the VVT for the motor).
Note: This would allow you to use most of the available LS1/LS2 cam design's without fear of PVT as the VVT could cause PVT issue's with a LS1/LS2 style cam... No data has been stated of which LS1 cam profiles will work without issue with the new VVT cam phaser system (so remove the VVT system).
Next up replace the tall Truck manifold with the Maggie style super charger (since it's a low profile) and set the boost to somewhere between 10 to 15 psi. As the Long block would still maintain a 9.67:1 CR
Additional stuff for extra power...
One of the many Blower Grind Cam's for a LS1 along with stronger springs.
The final product would be a air to air intercooled Supercharged megamouse
Just a thought...
Then again the maggie would probably set you back more then the L76 longblock
