[I have a question about the cam I put in my 350]

I've been there before and read some of it this time too. Starting to get a little more familiar with some of the specs, but it still looks mostly like Chinese to me. I was hoping someone would have had similar experience with small builds.

Would just degreeing this cam wake it up some, or just going to the next cam in line

I have one more thing to add. Am I expecting too much out of the cam I already have in the truck, or is it just a weak cam?

[I have a question about the cam I put in my 350]

I have a 1986 3/4 ton 4x4 long wheel base GMC that I rebuilt a 350 for. It has 202 heads, headers, and .30 over flat top Pistons. I put a small lunati voodoo cam in it. ( advised duration 256in262ex. Duration @ .050 tappet lift 213/219 with .454/.468 lift ). The truck has really good power from idle to 3000rpms, but then kind of slowly climbs from there. (spinning 37 inch military tires in dirt) I am wanting to put a bigger cam in the motor without changing valve spring, and other things. Would going to a cam with an advertised duration of 262/268. Duration @ .050 219/227. With a lift of 468/489. Make a big difference? Seems to be the next cam in line.
I'm afraid if I go bigger I will loose vacuum to my brakes and transmission, or have to run a stall converter.
Also what is the difference between advertised duration and duration @ .050 tappet?
