Crane specs?

[madcarson]

Anyone have specs for a 284H crane cam ? It's the cam in my 383 chevy but never got cam card from eng.bldr

I believe it's a single pattern 284/284 advertised duration with .480" lift, 2800-6200 operating range. I got this from the Jegs catalog and because Crane has gone under, getting a cam card's going to be difficult. If you really need to know the exact timing specs, find a shop thas has a cam doctor and they'll be able to measure it and give you a printout with the exact specs.
