Trying to decide on cam, 3 choices Hey. I'm trying to decide on 3 cams. Currently 216/220 .525/.532 114.
Application: Roadrace (sees 3,000 to 6,500rpm for about 2 hours per track day)
Want something more to compliment TEA S1 Heads (strong mid lift flow), Kooks LT's, and LW LS6 Valves. I'm going to run CC 918's, Ti retainers, and don't want astronomical lifts. Durability is key.
The cams I'm deciding on:
Crane Cams 224/224 .551"/.551" 114 LSA (3,000 to 6,500rpm, 7,100rpm float)
Comp Cams 224/228 .534"/.537" 112 LSA (2,000 to 6,800rpm)
Lunati 224/224 .560"/.560" 112 LSA (2,500 to 6,000rpm)
Anybody know how different the cam lobe profiles are between the 3 brands? I don't want some snappy drag race profile. I'd rather a less aggressive one.
I like the .551" lift on the Crane, but I also like the 112 LSA of the Lunati. RPM ranges are listed by manufacturers.....but unsure how realistic they really are.
Decisions, decisions, decisions.....Comp is $350, Crane is $400, and Lunati is $300.
Opinions please!

You might also want to take a look at the VHP cams, there are a couple there that would be good for the RPM range you are seeking. I went with the 216/224 .551/.551 115LSA and am pleased with the mid-range pull. Peak power is at 5,800 RPM, not what everyone is seeking but what I was looking for.

Personally, I want aggressive lobe profiles.

I think I'm going to grow some ***** and up my lift to .563" and go with a TR-224-12. Wonder if they could do a 110 or 111? The lobes on this cam aren't too aggressive are they? Was also considering the TR224-227.

I'm also thinking about the second cam on your list ie, Comp Cams 224/228 .534"/.537" 112 +2 LSA 110 ICL (2,000 to 6,800rpm). Less frequent valve spring changes, hopefully. I'm trying to locate a dyno graph and sound clip of idle but no luck so far.
