is there a cam for 1.8 roller rockers
i know this has been talked to death...but I don't think this question has been asked. Is there a good street cam for 1.8 roller rockers. I already have the rockers or I would not be asking. The motor is stock 02 ls1 ws6. I want it to be DD. I have gears 3.73 and stall, 3500. plus wet kit. and all the boltons. including t/a,LC,SB, and beefed up 10 bolt ( yea she is one tuff rear end...just kidding) What do you all think...total lift around 560? may be a z06 cam cheap?

Do you mean PTV? One thing you need to keep in mind is that the Crane cams have more duration at 0.004" for the same duration at 0.050" of some of the faster open cam lobes. For example, a 224/224 cam at 0.050" from Crane and one from Comp (XE-R lobes) will show a larger duration when the valve is first opening. Put another way, I believe they are opening the valve earlier but at a slower rate. So PTV can still be an issue, maybe even more so. Make sure you look at both the open/close duration and the duration at 0.050" when comparing the cams you are considering.
