An 85 Mustang with a carb was just about 205 or 215 I will have to get the number out of my book. The Lin. has a different cam and gears from the mustang. I do know that the 90 Mark V11 has the same set up as the intercepter mustang minus the 5spd. These are very fast cars for the weight they more down the road.
I also know that the 93 Cobra was under rated from the factory. I believe they were rated at 235 or so stock but everyone that I have seen on a dyno has put out close to 275 at the rear wheels.
