I have a 1970 convertible with a 351W (393 stroker). I have an C-6 automatic. I chose Heddman Shorty Headers, which are powdercoated. This was to avoid interference under the car. It was a tight squeeze. I used adjustable motor mounts, which helped clear the steering box on the drivers side. I have custom exhaust that was fabricated by Latoracing (on the fourm). Mike can pipe in with details if you need them. The challenge with convertibles is to get the crossover pipe in, and then get the exhaust pipes routed in the space above the convertible re-inforcing plate under the car. We also decided to run the exhaust out through the rear valence, where Mike did his wizardry with sheet metal and exhaust routing. Came out cool. I used Magnaflow mufflers. I actually have not heard the car run with the Magnaflows, but it will be louder than most people like. I am sure you will get a lot of suggestions on the mufflers, there are so many choices available. The headers are really high quality and fit without any denting/hammering. I also used stage 8 locking bolts. The bolt locations are a bitch to get to, so be patient.
