Engine Special - Chevy 406/400-9.0 Gen1

With 500Hp and 510lbs of torque, creating peak Hp is at 5,800 rpm's and peak torque is at 4,500. This is great all-around power package for hotrods and streetrods; torque is high maintaining a nice power band finishing up at 6,200 rpms. Idle quality is great at 850 to 950 rpms creating about 10-12 inches of manifold vacuum to run power brakes. To keep the cost down we installed a flat tappet mechanical camshaft and roller rockers. The compression ratio is 10.5 -1 requiring the use of 93 octane fuels. In this engine combo we used an open plenum intake manifold to shift the torque curve higher in the rpm band.
