I've heard and read lots of 12 second stories about the 273. The one thing they all have in common is headers. You have to let the air out of it. I suspect the engineers used the exhaust manifolds as a rev limiter of sorts. If the engines were supposed to rev past 6K the tach would have registered above 6K.

Now does this sound like a 273 dartcharger engine to you? Well it is... all stock internals. I just added a ld4b intake , dougs headers , 2.5" xpipe , 2.5" ultraflo muffers , 2.25" tails and swinger chrome tips .. stock carter 500 carb , electronic dist pertronix kit , and cold plugs .. What a beast ! that tweeking really woke this little 273 up. unbelievable . the video is half throttle rresponses ... revving to around 6 grand.. this engine loves 7000 rpms and up Bangin the gears ..
