Shelby 1 Series 4.0 V8 (Upgraded L47)

A Shelby version of the L47 4.0 was designed, not much is known about this motor other than it has the L37 4.6 more aggressive cams, an increased compression ratio and a redesigned head. These upgrades bring the horsepower output to an outstanding 320 horsepower @ a high revving 6600 RPM. This motor keeps the complete stock bottom end, and some versions have a supercharger cranking out 600 horsepower at over 10 psi on a nearly stock motor RELIABLY! This motor was mainly produced for the Shelby kit car, but many people swap this motor into fiero's and other cars, 1st generation aurora owners also swap this motor as well because of the 70 horsepower output!
