Camm Help???
I'm sure i could have googled it..but i prefer my Vette friends to help out. I'm getting a cam kit...leaving factory heads...what size cam will help me with performance and AWESOME sound without doing any damage to motor. I'm not a racer at all and its not a daily driver. 6 speed by the way if that matter. And what does the numbers mean associated with cams?

for the awesome sound, go with something like a MS3 cam from Texas Speed.
Camshafts are listed by the number of degrees of rotation that the intake and exhaust valves are open, commonly referred to as duration. This duration is listed by the manufacturer as either "advertised duration" which is normally from a valve lift starting/ending at .006" or more commonly listed as "duration @ .050 inch" which is from a valve lift starting/ending at 0.050". The next set of numbers used in a camshaft size is the amount of valve lift in inches. A third design spec is the lobe separation, or number of degrees between the exhaust lobe centerline and the intake lobe centerline.
But if all you are interested in is the "awesome sound", then just stick a huge cam in there and enjoy the lack of low rpm torque, minimal vacuum at idle, and live with a little surge and some additional valvetrain noise plus reduced fuel economy. Oh yeah - your going to be replacing valve springs every 20k miles or so...

If you want a genuine performance improvement, I would recommend getting LT headers first, then a performance cam. (or just a bigass lumper) Although you may achieve a greater HP gain from a cam install, it would perform better with headers. You'll need to upgrade your valvesprings; no option here. You should at the same time replace your timing chain, get quality pushrods, and optionally replace your oil pump with a high volume, and buy an underdrive pulley. The stock pulley has been known to fail often, so it's just a good idea to replace it since it's so difficult to get to your cam. With stock heads, and no headers, I would go with about a 230-234 @112 with about .585 lift. This'll lump pretty good, and still be drivable, with a good tune.

I would suggest a G5X3 cam from LG Motorsports. I friend of mine had one and it had a awesome sound and drove really well. I have the G5X4, awesome sound but wouldnt recommend for a daily driver. Good Luck!
