| Several dynoes that i have and in this instance te stock cam setup did very well. Obviously my sample size is a lot smaller so its not a conclusion i have fully accepted yet. Was just stating what i am seeing. I also feel that wi smaller turbos the stockers seem to do quite well vs just bolting on 500+ cams on stock heads. I guess my point was that in order to get 500+ cams to work well you need additional work. As you stated cam gear timing, as i stated headwork and bigger valves. Further, incorrect combinations of heads and lower plenums will obviously have a negative effect on timing. As you stated degreeing cams when you make a slew of changes on the engine can only help. :) Harry
