In another thread I mentioned I wanted a deeper sound from my car and someone suggested chambered inserts.
After listening to sound clips I ordered Sweet Thunder chambered inserts. My glass packs were a little challenging to get out but it didn't take too long. Once I installed the sweet Thunder inserts and started the car I was smiling ear to hear. Holy crap ! My 350 is aggressively built with lopy cam - add these inserts and its exactly what I was looking for. At idle the car is mean sounding, under throttle its not mean - its down right angry !
I generally take first gear down my street at about 10 miles an hour to keep it quiet on my way out. My neighbor was outside so I took my foot off the gas and the backfires were amazing. I was totally focused on the sound every time I layed off the throttle to shift. I need to record a clip for you guys - just don;t know how to do it.
I took off of work and drove it a lot today, I also posted in another thread that when I drive it and it gets hot there is a metal click / clunk that comes from the bell housing when the clutch is released. I really think i installed the throw out bearing incorectly. I went to the Vette Shop in PA (not sure what town that is) I asked them how much to install a new clutch and they said $700 (ish). What do you think of that cost ? It's a lot of work to pull the shifter and linkage, trans (cross member doesn't come out of my car) and then the bell housing. Then to boot I already did it wrong once ! but that's not to say I am afraid to try again. $700 or so seems kinda fair as opposed to me climbing under the car and doing it -- but I thought I would get your opinions.

Just put in a dual exhaust chambered set from MidAmerica and it sounds fantastic on my 79. This motor is stock but it gives it that great raspy rumble from a chambered exhaust and fits all of the stock mounts/manifolds. Great kit and very affordable.

It make sit nice to have a garage with a pit to work on car with. $700 is kinda much I think, but I dont run a professional shop. It's only a few hr job + / - in and out. But then I have had mine out so many times can almost do it blindfolded :) Good luck with what U decide. I live in Pa also in Berwick.
