High throttle miss

[Texasdoc]

Question: Would a cam that is incorrectly degree'd cause a high speed miss? I degree'd it when I installed it, but if I made a mistake then, would it cause a high RPM miss? Just grasping at straws here. I don't think this is the problem as it ran great with the EFI (whenever the O2 sensor decided it wanted to work that day). I don't remember what I ended up setting it on but I think it was advanced.

I also had to use a shorter timing chain due to excess slack from having the block bored/honed. I doubt a shorter timing chain would affect the cam to crank position enough to cause problems.
