Trading Duration For Lift ? I'm currently running a Comp 216/220 .525/.532 114 in my 99. (see sig). What would be the effect of swapping a 02 LS6 cam 204/218 .551/.547 117.5? The car has Lingenfelter Stage 2 heads. I'd be trading some duration for more lift and a wider LSA. I'm getting tired of misfire codes screwing with my T/C lockup. I have a LS6 intake that will be going on the car also. Your thoughts please on how the car would feel with this swap.

Re: Trading Duration For Lift ? My thoughts are get a bigger cam and have the car tuned. Then you won't cry everytime your SES light comes on. And you will run faster than you do now. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />

Re: Trading Duration For Lift ? Do you guys want to give me $400 for a cam, $180 for springs and $650 for tuning? Didn't think so. I can get a 02 LS6 cam and springs for $200. Now does anyone want to answer my questions? <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

Re: Trading Duration For Lift ? imo, i wouldnt change i had a slightly larger cam w/no misfire codes. maybe its not the cam, but if it is then keep the cam and get some tuning, i got mine from ragingmotorsports for 300 and i had it back in 2 days.

Re: Trading Duration For Lift ? Another slightly more aggressive grind to consider is Comp part no. 54-424-11. Specs are 212/218-.558/.563-115LSA. Smooth idle; won't need tuning. You should be able to get it for south of 400 bux. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: Trading Duration For Lift ? Keep the cam, get the tuning. That's what I did.
I got 366 rwhp/347 rwtq (corrected) with stock heads, stock LS1 intake, and a low-lift (.510) long duration (228/234) cam, running through cats.
Now that I've seen the specs on that new LG cam with a duration of 232/240, I will definitely try adding a set of the SLP 1.85:1 rockers to my setup. I was told this was way too much duration for the stock heads. I'm not convinced of that anymore. The rockers would give me around 233/237 duration with around a ~560 lift. I think I could get pretty close to 390 rwhp with the rockers and an LS6 intake on the stock heads. We'll see. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
