This is a very popular cam and I know many people have it here. I was wondering at what rpm's are you all shifting with this cam. I am currently shifting at 6200 with this cam and it seems it is still pulling very hard. I was ceonsidering raising my shiftpoints maybe 6300-6400. What do you all think?

I'm shifting mine at 6200 too. I thought about bumping mine up as well, but I don't want to push it with the stock rods and bolts. Is anyone else shifting at higher rpms?

As soon as I got EDIT I bumped the shift points up to 6500rpm. Went from 15.2-15.3s to 14.7, and picked up about 3-4 mph. The cam really wakes up past 6k. And I did it on an otherwise stock motor.
EDIT: Just thought of something--when I got the 4.8 dyno'd with the 212/218, I had the HPPIII and 6200rpm limiter, and remember that the graph was still climbing strong at the rev limiter.
Sometimes I wish I'd have kept the 4.8 and built a tranny/rear instead and gotten into the 13s with it. My mph was definitely there, just needed traction.

I am not afraid to rev my engine to 6400-6500 since I currently have 918's valve spring and TR hardened pushrods. I was just a little sketptical because according to comp cams this cam power range is from 1800-6000. Looks like i will bumping my shift shift points to about 6400. Anybody have any dynographs on this cam?

That's pretty much how I understood it. Different durations are needed to get the same effects from different CID's...
My 210/218 seems to sign off around 6,000 in my 6.0...
