We never paid a lot of attention to these things as we bought the car race ready. It always ran pretty good until it didn't. Long story short we had a cracked cylinder wall. A new block some machine shop work our engine guy assembled the engine along with a new MSD opti spark. We cannot find (yet) any issues with the rebuild. But the car is lazy and extremely inconsistent. I could be wrong but it sure acts like timing issues
