Timing

I ran that same set up (360 .030 over) in one of my cars. That XE268H camshaft loves lots of timing for some reason. I got to the point where I was timing it by ear and by how hard it started when it was hot. Not really the correct way that's for sure, LOL. I just changed out that cam for a Lunati 10200703 camshaft. What a difference. Must be something about that grind? Glad I wasn't the only one.
