...Hate to go through all the trouble but when it's no fun to drive I either fix it or park it...
That statement really makes me suspect that you have something other than cam selection going on. I've been around some street cars that were
way over-cammed, probably to the point of hurting performance more than helping, but none of them was so unpleasant at idle that someone would contemplate changing the cam for just that reason. I don't have a strong opinion as to what's going on, but something in that 8V setup would be my first suspicion. I'd sure hate to change cams before exhausting all other possibilities.
