dual exhaust on a 273
Hey Crash,
Check out my little thread in the early a-body section about the tranny mount modification. I used the TTI instructions from my exhaust kit. It was very easy to do and you will be setup for the tti's if you got that route. Or you will just have better clearance for dual exhaust from the muffler shop. It took me about 2.5 hours total time including sandblasting, grinding, welding and painting.
