a few weeks ago i made a similar post but it got off track and i didnt get much help, so i thought i would try again. I just rebuilt the motor in my 1970 el camino. Its a 355ci with 410hp. It has vortec heads that have been ported along with the intake. it has an Edelbrock 600 cfm carb. Its around 12:1 compression (i know its a bit much but its just the way it ended up). It has a 278/288 duration and .420/.443 lift cam. at the moment i have hooker headers with flowmaster super 44 mufflers dumped before the axle. I do like the way the flowmasters sound but im looking for something a bit louder and more crisp and crackly/tinny/snappy. Thats the best way i know how to explain the sound im searching for. I was hoping you all could suggest some mufflers that could get me close to that sound. videos and soundclips are always helpful!!
