choose my cam!! I have a 2002 z28, 6 speed, with catback and lid and ran a 13.019@#110 on street tires. I want to get a mild cam, with some lope, but not too much. What is the "safe" zone for lift on a cam?? I'v heard the T1 idle and it was a little rough for me. My car is a daily driver, occasional weekend track. Will the duration and lift affect idle quality?? or is that only in the LSA. I plan on keeping my heads stock, and mabye adding headers down the road, but keeping the cats. Would a split duration cam be best or do the ls1 heads flow good enough to keep a single pattern w/ stock heads, manifolds....etc. What's a good daily driven performance cam?

Re: choose my cam!! doesnt the 114lsa vs the 112lsa loose low end torque and make power higher in the RPM's?? Its a street driven car, and I don't want to loose out on the low end.
Re: choose my cam!! A 112 will give a little better bottom end, but you said the T1 (221/221 112) idled too rough, so I suggested the 114 LSA.
How much bottom end do you need? How often do you use WOT at 2000 rpm or even 2500? There's going to be some trade off. Comp's 212/218 114 is very popular for people wanting really good bottom end, but it will not give you as much up top. You could also take the 216/220 and order it with a 112 or 113 LSA.
With headers I'd bet a 218/218 113 would work nicely. Pretty good idle and reasonable balance of power.
Good luck. Try to rank your priorites. The difference of 2* of duration will not be a huge deal in terms of power, so try not to sweat it.

Re: choose my cam!! When you said the T1 was too rough, was it choking on itself? Or just reaaaaaly lopey? I have heard a B1 run, and it lopes real smooth, how much more agressive is the T1 with the 112 lsa? Any sound clips?!! <img src="graemlins/burnout.gif" border="0" alt="[Burnout]" />

Re: choose my cam!! I highly reccomend my cam
Its a comp cams custom grind:
222/222 .563/.563 112lsa
Gave me some HP.....
I dynoed 325rwhp and 333rwtq before the cam, new #'s in sig <img src="graemlins/gr_cheers.gif" border="0" alt="[cheers]" />

Re: choose my cam!! what's the max lift you would go w/ for stock heads?? and what else do I need for a cam install besides springs. I'm assuming the comp 918's are good? What about K-motion? What lift does the comp 216/220 have? I guess I wouldnt mind the rough idle, as long as I dont need tuning.

Re: choose my cam!! You don't need tuning with the 112lsa with the 6-speed....the best thing to do would be to drill out your TB and it would be fine....
I'm not sure what the max lift is for stock heads...

Re: choose my cam!! screw it. As long as the t1 doesnt need programming w/ the m6, are there any other cams around the same specs that perform better w/ stock heads? Is the near .560 lift too high for stock heads?

No. Hundreds and hundreds of people have chose the T1 and B1 with stock heads before you, things have not changed since they made power. .560 lift is fine.

Re: choose my cam!! Perfect cam for you: MTI/Lunati B1
I put it in my c5, which I dont plan on going overboard on, and will keep cats and be a (more) daily driver type car. Perfect slight burble in the idle, but nothing as shaking as the C1 (Hammer Cam) or the GM Hot Cam that have been in my SS.

Re: choose my cam!! with stock manifolds, I would go split pattern.
218/222 114 LSA and 2 degrees of advance ground in, rapid ramps with some good springs.
Off the shelf compcams you might consider are the 216/220 114 and 218/224 114.

Re: choose my cam!! I am "thinking" of changing my valve train some time. Before I get to doing this, I will be doing Hooker LTs and side dump exhaust. I drive the car every day so it has to still be "streetable," but I am looking for the roughest idle I could get to work. What would do this for me?
Re: choose my cam!! Also remember you'll be leaving alot of HP on the table without Headers to take advantage of the flow.
I went the Header route first and picked up some good power.Now my Cam is coming.I chose a Thunder Racing 220/220 .561 lift 114 duration for the good idle and ability to pass emmissions.Should have it in by the end of next week.I'll update what I think.

Re: choose my cam!! The T1 and B1 from MTI are very nice, but why don't you get some tires, so you can actually use the power, I run the same time as you, but I only have 309 RWHP, because I have <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> traction, Traction is the name of the game! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
