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.

With a 2.59 rear and your minor modifications I am thinking small is good.
Probably want an approx. 114LSA for it to idle
I would call Patrick "G" and have him spec a cam for you. He did one for my road race Vette and it worked just as planned for my application. Most cost effective $25 I have spent on a race car.
Geoff at EPS is also great.

Well, I'm looking at a MS3 cam and .650 springs from Patriot. Almost the same combo as we put into my son's car. He has ported 243's and I have stock 241's. The 1st gen will be around 3K at racing weight and will have a manual trans. Drivability is not a huge concern because this will be a track autox car and not a DD. I'm looking for Peak tourqe in the midrange pulling hard up to about 55k or better.
How do I get in touch with Pat G?

I have the VRX4 cam in a crate LS6 stuffed into a 944 turbo race car. At the bare minimum I would put in new rod bolts. My craigslist Ls1 motor lasted 20 minutes before throwing 2 rods. Also beware of the issue with sweeping left handers causing transient oil starvation. Many racers recommend running Accusumps

I will say this though, that cam gives some great power. I was able to stay on the tail of a Porsche GT2RS down the front straight of Texas World Speedway. That is a $250k top of the line Porsche street/track car that is rated at 620hp. I was hitting 155mph at the end of the straight with no problem. For comparison, I have a 700+ awhp 911 turbo that hits 160+ on the same stretch. My 911 weighs 3500lbs, the 944 with LS6 is probably around 2500-2600 lbs

Does the ASA cam need ported heads or higher compression ratio to fully utilize it's potential?
I see GMPP lists 2 CNC ported LS6 heads along with the GM Hot Cam and Showroom stock cam.
Does anyone have experience with any combination of these in road coarse application?
