Any luck with CompCam 415?

[Christian Dionne]

This cam was purchased two years ago and I kind of guessed at it. We knew everyone had .500 lift, I just guessed at the duration. The 415 has 210/215@.050 compared to the 412's 206/210. Has anyone tried this cam and what kind of results have you had? The engine pulls to 6500+ easily with ported Vortecs, ATR headers, PTE63E, etc...

I've run some comparisons with a Dynamic Compression Ratio calculator and the 412 has 6.96:1 v. our 6.83:1

The 422 cam has 215/220@114 lobe seperation and the DCR would be 6.76

.2 difference in dynamic compression shouldn't mean too much, I just think the Vortecs like the extra duration.

I'd like to hear what cams other 10second builds are running.

Christian,

I was going to go w a 415 because the 412 looked a little mild. Then Conley talked me into a wilder cam that he has been using for SyTy's. I am a little worried about streetability. Here R the specs :

Duration @ 0.050" Lift - 224 Exhaust / 220 Intake

Lobe Separation - 112, installed retarded to 108 for Low End.

Lift - 0.525" Exhaust / 0.510" Intake

My engine builder wanted to use a 224 single pattern, as his old combo went 10.ohs and idled at 850 with 83#ers. We probably could have used his program to get a good baseline. My buddy's twin turbo has a 236I/224E reverse split cam in his 355ci SBC. It's pretty wild on the exhaust note, but pulls great vacuum and spools instantly.
