Allen's Stainless Exhaust

Chambered exhausts are straight through pipes, no mufflers. And they are ILLEGAL in certain states. Check it out before you buy one. BUT, IMHO they sound very raspy and sharp. Assured to make neighbors hate you! I ran 2+1/2in pipes on full length headers into 12 or 14 inch turbo mufflers, (available any where) and that produces a nice mellow rumble until you put your foot in it, then music.....and it's all behind you which is nice and easy to live with. If I remember the long pipes had to be squashed into ovals to go through the frame, but it was easy for a shop to do. Check the outlets...you may be limited to 2+1/4 outlets so that's what you'd run. I filled those holes in the rear valance, which by the way you would have to fill with side pipes as well. I ran straight out the middle with slight downturns like old Jags had. Looked very cool. (no spare carrier)

Rear end ratio is on the housing. Get the number off the housing around the drain plug somewhere, and look up that number to get the ratio. Stock was 3.36, but you could have anything in there. My 66 had 3.08s for the highway, and I put in 4.10 which was the wrong one for me. Absolutely no good on the highway. What does it rev at 60mph?
Gene gave you the old way to check, and really the only sure way.

And can you hold a conversation inside the car with the top up and driving around town?

Personally used the Eckler chambered system on my '71.

Small block, non headers. Included stock appearing tips, (rectangular). Kit fit perfectly, everything included.

Sound was more aggressive, BUT, not overpowering, even with top down which was 95% of the time. Good sound at hammer drop.

Would I buy another system? YES.

I would run the chambered exhaust. I would buy a good set of tires. By good, I mean sticky performance tires. the only issue with that is you will throw a lot of sand on the body.

I'd look into the RPO N11 "Off Road Exhaust" mufflers myself... definitely louder than the standard cans... Corvette Central has them for a couple hundies...

Some clear wrap on the trouble spots and that sand problem is solved...

That does sound sweet.

Based on old and questionable memory. Rear gears in most mid-years would have been 3:08, 3:36, 3:55, 3:70, 4:11, and god forbid 4:56.

My original 63 340, close ratio trans, 4:11. Blew the rear and tried the 4:56. That lasted all of a week before I pulled them and went back to 4:11.

If you have the wide-ration trans don't go lower than 3:70. If you do the car won't run as you expect. Also at 70 mph the 4:11 turned the engine at 3K cruise. OK in a ragtop with top down but hell with top up or a coupe.

Look at the Edelbrock Performer RPM kit. Cam, heads and intake all together. little under $2k. They have more than one kit but one has heads that have 185 cc intake runners. Move a good amount of air with good air speed. Matched cam should thump a little. My C3 had Hooker headers/sidepipes when i got it. Sounded great. I put unde car pipes on it because my neighbors bedroom was 25' from my car port and it rattled their windows on cold mornings. Damn I miss those days.
