When you bumped the timing to 19 , did it feel like you freed the motor up?
Yes, Yes and did I mention Yes. LOL Here is the other reason I feel like I should start a little low on timing is because this C&S blow-thru carb has been a challenge to tune and I want to make sure the A/F is not lean as I move up the boost and RPM's. This whole combo is new and completely new to me so I have a learning curve and I don't want it to cast me custom pistons again. I plan to only make enough pulls to establish acceptable A/F then move timing up from there. I don't want to get ahead of myself chasing a big number......
