The 6L Vortec marine engines are also entirely suitable for placement between the fenders of a Corvette. The naturally aspirated model is essentially a "marinized" version of the engine that powers Chevy and GMC trucks and SUVs. In its marine form, it's rated at 350 hp, which is the minimum power rating it will carry if it hits the Performance Parts catalog. With a cam change and slightly more aggressive ignition timing, the engine will easily crank out 375-plus horsepower and yet be mild enough to deliver excellent low-speed driveability and fuel economy.
