Two for the books...
Clint Barnts, NA 2.8, Mustang Dyno, stock intake manifold, stock cam, massaged stock EFI, square port Braap head, Electromotive DIS, 8.1 Comp, 6-2 header, 2.25" exhaust... 160HP/161 ft/lbs (at the wheels). AFR's a bit rich particularly at torque peak. I believe another 5lbs/5hp is attainable with a smidge more tuning.
Mike Hintz, NA 2.8, Dynojet, stock intake manifold, stock cam, massaged stock EFI, round port Braap head, re-curved stock igintion, 9+ Comp, 6-1 header, 2.5" exhuast, 146HP/152 ft/lbs. AFR's fairly close.
Both indicate the possibility of breaking 200 crank HP with the stock intake manifold and street-able exhaust.
Additionally, both of these cars are in the middle of... uh, reform... more numbers in the future.
