Road Race Cam Suggestion
I'm finishing up my LS1 swap into my 67 Camaro that will be used primarly for HPDE's and Autox duty, My friends have just about talked me into a cam swap while I have easy access to do so. What you guys suggest for Road Race Duty? 2500 to 6000 rpm? The motor is a 2000 LS1 with an LS6 intake, Headers, emissions deleted, ported TB and it has 241 heads that have not been touched I assume. The motor has 112K on it now, not looking to spend a bunch of money, just swap in a new stick and put it back together. What spec cam would work the best with those simple mods? I have fuel upgrades too, Walboro 255 pump, adj regulator and high flow fuel rails. I assume the injectors are still the stockers at 26lbs, but I'm not against changing those out.
Forgot to mention that its backed up with a ST10 4speed tranny and a corvette IRS with 2.59 gears (I think) from a 96 auto C4.
I'm looking at a package with a MS3 and upgraded springs and pushrods oil pump and chain. Is that too much of a cam for RR applications?

We have road raced ex ASA stock cars for years with the GMPP parts ASA hot cam. It is only .525 lift but pulls hard to 6500 or so and is easy on the valve train.
Look below for the video of the V8 StockCar ex ASA car road racing at Sebring, this would be a 5.7 LS1 with stock compression, ASA cam, 90mm LS2 throttle body and manifold, headers and ECU tune. Makes nearly 500 flywheel hp. Check out how competitiive that thing is.
Schwanke Racing Engines built the motor in that car.

I have 'HotCam' in my sig, but in reality it's the hotcam with a tad change in duration (220/224, 112LSA) and it's great on the track and the powerband you want. I've very happy with this cam for all my needs (cruiser, track days, daily driver, nice cam idle).

Thanks Kevin,
The motor in the car has 114K on the clock, I practically own the 224/230 .581/.588 114 LSA Cam, All I have to do it get it from my son's garage. I think I'll throw that in the motor with a 2deg advance and see what happens. I have some Patriot .650 springs that I'll also put on the heads as a safty measure, and I might even pull the heads and port them. I have a good set of OBX stainless long tubes, and not very restrictive exhaust.
I'm still in the stages of building this car, but it's still not ready for track days. Maybe by the late summer or fall, if not it'll be next year.
I'll be at VIR in March with NASA driving the WS6 in my sig. I'm in the HPDE 2 run group if anyone is there look me up.

Cool man. I'm going to be picking up another car here in the future and turning the GTO into something more extreme. I like the idea I'm always the only GTO on the track because people ALWAYS ask me questions when they get passed by on. haha
Interesting, I was invited out to VIR last year and didn't go. I may have to save my pennies and get out there one of these days. It looks great.

I have a 224/224 @ 114 that was in the car when I bought it. It barely lopes so I was thinking about going a bit bigger myself. That 228/230 looks good! Any vids of it idling?

I'm using the GM hotcam with Katech heads and a FAST intake. Car still running very well after a dozen track days in 2 years. The lower lift and 112 LSA makes it easy on the valve train while keeping good torque at 3000rpm where you need it accelerating out of the turns. I believe the ASA cam is a 110 LSA which may not be very street friendly but is definitely a proven road race cam.

ASA Hot cam kit w/springs: GMPP 12480033 = 219/228 0.525/0.525 112
ASA Cam 12480110 = 226/236 .525/.525 110
I could not find the kit or a cam with the same specs as the 12480033 at GMPP. It appears as if the 12480110 has replaced the 12480033. I have not called GMPP to confirm.

[EDIT] I think I understand now, people use Hot Cam and ASA interchangeably when in fact there are two cams with different specs. The "Hot Cam" is the milder of the two cams. The "ASA" is the hotter cam.[EDIT]
Thanks

Which cam are you referring to, the 219/228 0.525/0.525 112 or the 226/236 .525/.525 110

I don't "race" (track days are not races, so they say), but at my track days I actually feel bad for the car and never go over 5800-6000RPM. The average RPM isn't as high as you might think. I stay in 3rd and 4th most of the time. Accelerating out of a turn is hard to do at WOT with this much power in a low gear (1st or 2nd). Mid range torque is my suggestion to shoot for.
To the OP - are you going to race the car, or just track days? There IS a difference. Racing you want every last tenth you can get. Track days, they don't even time the laps (most of them anyway) since it's not a competition. It's meant to have fun, push your car, but at the same time, in a safe environment.
I have no regrets with the hotcam. As someone said, it's easy on the valvetrain and I like the torque and response of it. If I were to change anything, perhaps a tad more duration and lift, but not much. I don't feel you need a high RPM cam to enjoy the car out on the track. (however, with that high of a gear, you may need some more power).

Ageed, racing and HPDE is different. I'm still working my way up through the HPDE ranks, but while I have easy access to do a cam, thought I'd ask what you guys are using. Car won't be a dd, but not full race either. Doubt I could make a 45 year old car very aero worthy anyway. I'm just there to have fun and pretend to be fast!
