04 C5 6 speed 54k miles. Full exhaust. “Top Speed” not on yet. Ti axle back. Stock motor. C6 Z51 sways C6Z06 shocks. It’s my daily driver. Not gonna auto cross it. Maybe a few passes down the track. Just want a respectable minimum 400 HP almost matching torque. I seen the thread with the JEGS 228/230 .585/.585 112 LSA cam on stock heads, stock exhaust/bypass mod/LS6 intake/ headers withTI axle back/zip tie mod. I pretty much have the same set up. Sounds about what I’m interested in doing. Any expectations or advice on that would be great!
Fine with all the best push rods/springs/and head accessories, OEM gaskets. Best bang for my buck without opening it up every 10k Miles. Got my beater on the road so it’s time to put the vette up for surgery. Thanks

I went through a cam/heads project a few years back. Here are my takeaways from my research. Take them for what they're worth.
I have a cam with slightly more lift but slightly less duration. It's not in a daily driver for me but it could be; it's friendly. It may be worth taking to some of the cam sellers for input on specs based on your exact set-up. Specifically your heads and how you plan to use the car.
I have a buddy that works for PAC. He knew what I was putting together and for what purpose (fun weekend toy) and his engineer buddy at PAC steered m to a good single spring over dual valve springs. Duals offer good insurance but singles put less pressure on the entire valve train and are plenty adequate for the use you're describing above and generally up to .600 lift. PAC 1218's will work for your cam. They have an option of the 1218x, which are shot peened for longevity. PSI also makes quality springs. PAC and PSI are responsible for most of the springs out there regardless of whose name is on them.
Also consider upgrading the rocker arm trunnions, replacing the timing chain (a LS2 is an economic upgrade/replacement), the oil pump and the balancer. Not sure if you'll get to 400 hp with your stock heads. I have about the same set-up with 243s and barely cracked 400/380 on a dynojet. It's just a number on a dyno graph anyway. Good luck!

Thanks for taking the time to write your experience. Can you be specific on your gains made with your cam ? 1/4 mile times and and advances of note?

I went from 325/335 with a cold air and tune to 402/379 on the same dynojet and tuner. The build was 1.75" headers with cats, 222/226 112 .600 cam and 243s. Also did the trunnions, timing chain, oil pump, lifters and trays. No 1/4 mile visits, I'm not putting a roll bar in my convertible.

I just finished my build and I took it to tune last night. I now have a sister build to EVLGTO with minor differences. I kept stock 853 heads (but refreshed them with dual valve spring kit and cleaned the valves) and I got the same JEGS cam.585/.585/228/230 112LSA, same 42# injectors, LS6 intake, K&N cold air intake with K&N air bridge, Texas Speed 1-3/4 Long Tube Headers with Offroad Texas Speed X pipe mated to Magnaflow XL mufflers. I made 397WHP on a DynoJet. So far I love this cam and honestly anything more aggressive camwise would've been too much for me. Bucking is minimal, but still bucks a tad compared to stock obviously. It's just a matter of getting used to and changing my driving style since this is my first cammed car. Pulls hard, has a clean and flat torque curve and pulls evenly throughout the powerband and makes power all the way between 6500-6700, hence my tuner decided to put my rev limiter at 7000 and recommended me to shift between 6700-6800. FYI: Spark plugs used were NGK TR5GP (they're pregapped at 0.040"). Throttle coolant bypass mod was also done during the build. Definitely feels like 400WHP too. In summary, if you're thinking about keeping your 853 heads, you can achieve your 390-400WHP with this cam. I also have 90k miles on rest of motor.
Still, take all of this with a grain of salt because dyno numbers are just numbers, and highly dependent on accurate calibration. I agree with 'Time for a C5' on this.

i have the stock 241 heads. Great write up. Thanks for taking the time bud.

No problem. I'm passionate about this and obviously very excited for it since I just cammed mine. If you have any other questions, let me know and I can give you more details of my experience, since I come fresh from the bone stock feel.

Any chance you can take a behind the wheel video of a pull ?
Sure I don’t see why not. I don’t have a GoPro but let me see what I can do. I have a cell phone mount on my AC vent, maybe I can get creative.
Cool thanks! I appreciate it! I get my full exhaust put on next week. I went with “Top Speed” long tubes with X pipe and 200cell high flow cats. They market them as long tubes but there 3/4. Long story why I went with top speed instead of a more known brand but pretty excited to see how it goes after the tune.

Your dyno graph looks awesome. Wide 2,000 RPM near peak power. Congrats!

Thanks!! I couldn't be happier with the results. C5 rips like a raped ape and pulls all the way through evenly up to 6700RPM easily. I was impressed I got to near 400WHP with the supposedly POS 853 heads.

By the way, I tried to record with my phone but it's sketchy and dangerous as hell. I'm trying to get a hold of a GoPro or have someone ride passenger and record the pull. I haven't forgotten about you.

Yep, tried the same thing when I got my exhaust. Need a wing man. Thanks for trying.
Hi there. I'm considering my "first cam" too. My Z06 put down 405whp on a mustang dyno (New Era Performance) and I did a video this past summer of a few pulls for your reference. check it out if interested in seeing tach / speed here:

Crazy how you got over 405whp on a mustang dyno with a stock cam. That just shows how well those 243 heads flow. Awesome results.

Need suggestions for my first cam set up
or a last cam!
