My car has the regular 390rwhp C5 Z06 bolt on package.

LG Super Pro headers, catless X pipe, Vararam and tune.

Made 394/390 to the wheels (STD correction) today in high humidity.

I double duty this car, street and car shows in summer. In the winter I track it, 3-4 times while it's cold.

Like everyone I am looking for the most power with the lowest maintenance I.E. spring life etc.

I recently put PAC 1218X springs on, so that's covered.

I am looking at doing a cam change.

So what are you running?

What are your mods?

How much power does it make?

How is spring life?

How often do you track the car?

What pushrods do you run with it?

Got a dyno sheet?

Not quite "cam-only" here, but close enough. C5Z06 here as well. Car made 390/37x SAE with Kooks headers/x-pipe, Airaid air intake and remote tune.

My next stage was getting the heads ported by AI (226cc program) and an EPS 226/230 .604/.604 113 +3 cam. It was a 'custom spec' cam and I mentioned HPDE/extended high rpm use and desire for durability/longevity. Due to the head porting and work, I needed something like 7.300 pushrods, I'd expect 7.4 would be good for you...but why not measure first to be sure.

Had the remote tune tweaked and car made 435/40x SAE on the same dyno. Right around 450whp STD. I have a real dyno sheet and the actual run file, but rpm cuts out at high rpm, so it comes out a bit wonky- so I input all the numbers into excel for better graphing/comparison. Here is old vs new setup mentioned above:

I've been contemplating a cam swap also. I just havent had much time to do research on it. I've been eyeing the G5x1 and thinking of the livernois stage 2 heads as well. I do hear there are better road race cams out there now though. My Kooks, offroad x and haltech tuned car made 393/378. I would like 430/425
