Go down to exotic performances pluse's post. Checkout the 2nd or 3rd clip and 2nd to last. Bad ***.... I want that cam.

in short, yes. are you trying this N/a or with your current set up?

With the turbo. I am thinking of upgrading my valve train abit. I am thinking of patriot gold valve springs, 850 comp lifters, and maybe a set of roller rockers (shaft mount). I'll have my tuner design me a cam for my little 5.3. But I really love the sound of that cam on the ss camero, it looked like it really moves too.

I think that is too big for a 5.3. Flyer ran a 233/239 in his 5.3 and remember him saying that it was pretty tricky tuning it. Also, a cam that big is going to shine up top at the expense of low end power. Also, that cam in a 5.3 is going to lope a lot more and sound even more radical.

If you are running the STS, i dont think you are going to need something that big. Why not try a reverse spilt cam? Just a ?

Yeah you are right. My tuner wants me to run a reverse split cam as well.

Thought you couldnt have lope with a turbo cam? Obviously you can run a cam with 30*s overlap and it will work but I thought negative overlap cams work much better?

Lope with a turbo cam is not recommended on a street driven vehicle mainly due to them causing more lag since longer durations and more overlap are less efficient at lower rpms. On a race application, larger duration turbo cams are common of course. Most will run solid roller cams with extremely high spring pressures and have lobes with really fast closing rates to maximize duration near max lift, but limit overlap.

Going from a cam with -.5* overlap at .050" to one that has -22* at .050" made a huge difference. Boost came on faster and it seems like there's more of it given the recent oil control issues. Low end torque was increased too. It idled better, and my gas mileage went up. Seemed like a win-win to me.

someone either on here or on tech posted a formula to determine your overlap given your I/E durations and LSA, does anyone knwo it off hand? it was something like I+E/2 - LSA but i know thats not right, just along those lines
