Summit Racing reckon that you might be able to build a GM LS engine that can make close to the 530bhp and 495 lb-ft of torque this BluePrint Engines Pro Series engine does, but it won’t be easy or cheap, and it certainly won’t come dyno-tested or backed by a 30 month/50,000-mile limited warranty like the BluePrint mill does.

BluePrint built this 376 CID (6.2L) engine with the good stuff:

• GM 6.2-litre aluminium block
• 3.622in stroke nodular iron crankshaft
• 6.098in long connecting rods with bolts rated to 150,000 PSI
• Hypereutectic pistons, 10.7:1 compression with 72cc heads
• Hydraulic roller camshaft, 225°/238° duration @ .050, .612”/.585” lift, 113° lobe separation
• BluePrint aluminium cylinder heads with 259cc/102cc runners, 72cc combustion chambers, 2.165”/1.600” valves
• LS3 factory-style intake manifold with 90mm throttle body, fuel injectors, and fuel rails
• Coil packs, ignition wires, and Champion CPN-9405 iridium spark plugs
• Water pump, harmonic balancer, valve covers, and timing cover

BluePrint Engines includes a dyno test sheet with every Pro Series 376 engine. BluePrint recommends a 2200 RPM or higher stall torque converter with this engine.
