Old thread just wanted to say one thing, no such thing as a freak car, only freak dynos. Take all your freak cars to the drag strip and none will trap what the power indicates it should.

my car with 110,000 miles on it made 320 rwhp and 332 rwtq with only a lid and neutered catback. stock tune, stock ls1 intake, etc, etc. i think that's pretty healthy for a car with that many hard miles and so few mods. and it wasn't just a giving dyno that day either, i ran 12.8 @ 108 the night before on shitty kumho street radials cutting a 1.8x 60 ft. and the car hooks VERY well on the street. i dunno if that would be considered a freak, but it has put quite a few cars in their place that it shouldn't have (pulled on cam/bolt on cars off the line and held them off for 1/8 mile)

I don't think it is a s much of freak cars rather than miscalibrated dynos and better drivers with good air. Back in 2001 my car had 147 miles when I took it to the track on the second day I owned it. All stock to the paper filter and not adjusting tire pressure. resulted in 8.47 @ 87 mph that's with an auto.
Now I know these cars have mileage on them now, that is why lite bolt on cars are the running the same times as I did years ago. Realistically you can't really compare them as freaks as they are 7-11 years old various mileage and most of you are not original owners, an do not know the care given for the car. 147 mile car then may be within the power possibilities of a lid exhaust car with 50k miles today after all of the carbon and wear has taken place over the years.
Dynos are just a tuning tool track times are close but varies on track prep D/A temp driver skills and condition of the car running car EX; condition of motor, trans, rear end,shocks ect.

a friend of mine ran 12.7 bone stock.(F body) we figured his car was a freak. no dyno numbers. his car is far far from stock these days. sure, hes a bit of a wheel man. without calling him to ask, i think his mph was just under 109
higher milage car (within reason of course.. not a 150K mile turd) should be faster than a 147 mile car. your rings were just beginning to get acquainted with your bores at that point dude.. as the motor wears some it requires less energy to turn, and better cylinder seal will produce more power.

70100 mile 01 m6 camaro ss with pacesetters,gmmg,k & n cone filter,ported t-body,ls7 clutch,under drive crank pulley & a midwest fab9 rear with 410 gears sitting on pro star big & littles...
front & rear impact bars removed as well as spare tire & jack & thats it for weight reduction......
ran a 11.83 @ 115 with a 1.5? 60' in hot weather, 85 + if i remember right.
never been on a dyno,guessing 340 to the wheels ??????
i thought that was pretty damn good.

I wouldn't call it a "freak" since most of the 98 (F-Body) LS1's seem to dyno well. Making the same kind of Horsepower at the Rear wheels as GM rated them at the flywheel (305 hp back then).
My 98 (F-Body) LS1 dyno'd 316 RWHP with my electric cutout's closed, and 323 RWHP with the cutout's open. The motor is stock expect for headers needed to make the engine swap fit, and having someone remove the TQ Management, EGR, VATS and stuff from the factory GM "tune".
