All the LA SB Mopars I've tested and raced like 30 to 32 total timing, high compression or blue printed stockers I know of others that thought there motors like more but once the top dead center was verified and coordinated with the timing cover TDC marks they ran the best with 32 to no more than 33 degrees total I know racers that saw 35 degrees when I saw 32 degrees on the same motor with the same timing lights on the same day one after another It is called paralax(SP?) errors
