I've been reading all your posts/threads this morning and haven seen any follow up/ answer BY YOU to any replys------

Oh, well, considering that, I guess maybe the cam shaft answer your looking for would be to make sure that for the double roller timing chain that it have the 3 bolt holes in the front for the gear that your using, and dist/oil pump drive gear at the back--------also, a good idea for issues down stream are make sure it has a fuel pump drive lobe at the front as some cams don't.

On the issues of timing/lift/duration---------that 267 isn't ever going to make any decent power at driven rpms so any of the stock roller lifter cams from middle 80s would most likely be best choice-------
