Cams
I have an 06 Z51 and have done the easy stuff.
Kooks LT's Hi flo cats, Corsa sports, K&N intake.
Motorsport Z06 rims, and Firestones.
Now I want to get a cam. Looking for recommendations.
The car is a daily driver (at least 1K/month sometimes as much as 3K).
I want something that helps with perfomance and a little sound that lets you know it is there and also installers and aproximate costs in the Sarasota/Venice FL area. Any help/advice would be appreciated.
Thanks!

... though I'm afraid of losing mid range and off-idle smoothness. I love out accelerating any non-sports car on the freeway without have to downshift from 6th! (this is not stock performance- 6th is a DOG before the mods I had done) This isn't the only condition that awesome midrange is enjoyed a lot, either. I think more overlap/duration to get more hp on top is going to kill the mids... I guess just be very careful what you buy/install and be heads-up about what it will do. Good luck.

I understand. Not really looking for it on top but more midrange than anything. I am a little outdated but it used to be you get cams pretty much dialed in to where you were looking for the perfomance.
Sure gonna need help with this one.

No cam will appreciably improve midrange or low down torque. Only more displacement or better gearing can do that. The best you hope for with a cam is to have as much low rpm torque as you had stock, with , of course, the extra 50-90 hp on the top end. If you want to move in 5th & 6th on the highway, and haul azz in general, 4.10 gears are your ticket.
The consensus on cams seems to be that 224/228 is just about perfect in terms of adding plenty of power, while retaining near-stock smoggability and drivability. You will be miserable in traffic if you have a big cam.

If you want low/midrange power, I would definitely do 4.10 gears.
You can do the cam later. The 4.10 will make the car more fun than the cam. Unless you do both.

I agree that gears are a better mod than a cam. I did gears as almost my first mod. I waited a year then put in the cam. I hope I can hold out another year (and don't break anything) before I do heads.
Like you I was worried about losing low end torque in my daily driver. But I achieved my goal of not losing any low end by using Cometic .040 gaskets.
I put in a big cam, G5x3. Here's my write up:

Any my dyno sheet comparing cam vs. boltons only (note small difference in low end torque) and stock.

If you want added low-midrange torque and HP go with a reverse split cam. I installed the MTI X1 in one of my cars and it made power from idle to redline. You will lose a couple of peak HP with the reverse split, but if want a fun car on the street, you can't go wrong. At the track I went 11.30 with that cam, not bad for a cam not ideal for the track. More people should try reverse split cams, they are very much underrated. To many guys are stuck on technical specs and not real world results. That cam on my cam only car made 418HP and 404 torque on a C5. If you would like, I can dig up my dyno sheet.

Acknowledging in advance that I can't interpret "appreciably," "mid" or "low down" torque, I don't think this is quite true. Assuming some ranges for low and mid-range like 1500-3200 and 3200-4900, respectively, many dyno graphs of cam-only or cam-included installs posted on this forum have shown torque gains in these ranges. Maybe I mis-read it but I think I even saw a dyno graph posted about your car that showed the after results of a cam-included install. There is no before graph but your torque is pretty stout in both these bands. Surely, some of this was due to the cam.
ZeeVette reported 350 ft lbs at 2300 RPM's on a 5.7L with a 228/232, 600/600, 112+5. He had after market heads and a 10.9 SCR but these are big numbers. Others on LS1tech have reported low and mid-range gains with this and similar cams. I am not steering anyone to a particular cam. I don't know enough about it to do that. I just wanted to point out that low and mid-range torque gains are possible with a cam.
