A Mild Cam With A Non Aggressive Ramp Rate? Can anyone reccomend some cams that are mild with Non aggressive ramp rates. I dont want something that is going to slam the valve open and shut, I want to be as easy on the valvetrain as possible. I tried looking at what comp cams has but they dont list spec for every cam. Im looking for something with 216-222 Dur@.050 with between .530-.560 lift on a 114 LSA. Ive found two that come pretty close. Has anyone had any expeirence with these cams?
Crane 1449561 Adv. Dur.276/286 Dur@.050:216/224 .551/.551 LSA:115
Speed Inc. 1 Dur@.050:222/222 .563/.563 LSA:114
Comp Cams Dur@.050:216/220 .525/.532 LSA:114
Comp Cams Dur@.050:218/224 .527/.534 LSA:114

Mild ramp rates would be below .550 lifts
The Lunati cam is similar to the old MTI Hammer cam IIRC
Both are good cams but not really mild.
A good old timer is the Comp 216/220, .525/.532 114+4

With -10* overlap at .050 for sure, that Crane cam with a set of 1.7 variable lift rockers will make tons of trq, which is an added feature with the weight of the GTO.
Not a cheap setup, but worth it and very street friendly.
The only thing left to fully enjoy is a High Stall (I recommend VIG 3200)

That Crane cam looks like the one I just bought from Vinci as their Boss II cam. They have it in two flavors, 113 LSA and 115 LSA. I went with the 115 LSA. Am still waiting on the rest of my parts (gaskets, etc.) to do the installation.
Vinci has a sound file of that cam on their web site if you are interested.

how about the TR22O on a 114lsa,.553 lift?i run that in my car,and i like it a lot.it's not as aggressive as a lot of the newer cams,and with a set of 918s or some duals springs you shouldn't have to worry about changing your springs every year,unless you pound on your car a lot.

Not sure how long vinci cams can go without spring changes but crane told me several times their cams are good for 60-100,000 spring life. they have cars that go to 100,000, but say to check by about 60,000. SDPC has some sersiously inexpesive crane cams that work with LS6 springs, you can custom the cams to the specs you want if your not happy with all the numbers.

The three you added have an LSA of 114, if the Vinci with a 115 won't get by the smog police, not sure how these will either.
Have you been to LS1sounds.com and listened to any of the cams out there?

You can pick a grind using the Comp XE ramps. They are not as aggressive as the XE-R lobes.
TR's total lift is less than an XE-R, but the cam is similar to an XE-R from .006 - .200 so I would consider that aggressive. It helped make the TR 224 so drivable at time when tuning was fairly primitive.
If you are keeping the cats and going to tune it, I would vote for the 218/224 114.
Vettenuts: I'm not sure why Vinci was having problems with the smog police. A TR 224/224 114 has passed emmissions in many states. It does have faster ramps, so overlap at .006 is more like a 222/222 XE lobe cam. A 218/224 114 on the slower ramps will have maybe a hair more overlap at .006 than the TR 224 114. A good tune should deal with it. For an abundance of caution, an alternative would be to use a 115 LSA or go to 216/224 114.

Comp Cams Dur@.050:216/220 .525/.532 LSA:114
This would be my pick. With a good set of heads this cam has made 400 RWHP.
I'm running the TR220 - 114 and love it. My car doesn't sound like a sewing machine. I get some valvetrain noise from 2000 - 2200 rpm but its not bad.

The comp 216/220 is a great little cam. You can hear it with an open cutout, but would be disguised nicely running through a muffler. You'll pass smog with flying colors. With this cam you also won't have to worry about changing springs for a long time.
