Oh no a stock 5.0 lost to modded car?!?! a 200hp 3k lb mustang couldn't beat a 170 hp 2400-2500 lb car?!?! It's no secret the motor was underpowered from the factory, it's also no secret that with exhaust, intakes, heads, cams, any combination of these mods open up serious amounts of power.
your story is a poor attempt at a pissing match, Farley
