cam experts please check this out ok, i am going to cam my cts v BUT, i plan on keeping the stock exhaust system. I KNOW, I KNOW, im handicapping the car alot, but i have my crazy car, this is just a fun family hauler, it replaced my TBSS. i was thinking of going with a 224 cam with lift low enough to use the stock yellow springs so something in the .560-.570 range and keep the lope down so a lsa of 114-116. im no cam expert so what i wanted to know is this, with the handicap of the stock exhaust what can i change about the cam to optimize the gains. will going with more duration help or tighter or looser LSA give any better gains? thanks in advance for any help.

It is not only a question of lift, it is also and mainly a question of open/close seat pressures. GT2-3 from Lingenfelter is one of the cams known to be handled by those springs IIRC.
Others just simply have too harsh lobe profiles and require spring chnge.
For your car with stock manifolds, TR CheaTR V3 cam would be worth a look at, will need springs.
