This is the motor that is in my Orange Z28 now. It made 490rwhp on 104 octane with a mild tune and makes 460 detuned for 93 pump gas though a Ford 9" with 433 gears. Motor has about 1000 max street miles, about 12 dyno runs, and has NEVER been down the track. I just want to go a little milder and bigger. Here all the details of the motor.
