Still having our overtemp problems, I thought we should nail the timing down to make sure that isnt the problem? Runs fine, just hot! Rebuilt 289 with about 400 miles on it, Edelbrock rpm cam, intake and 4 barrel carb. Could someone jot down the "timing by ear" procedure again? I think our harmonic balancer has slipped. We have Tri-y's and dual flowmaster 3 chambers so it may be a bit tricky to hear it ping but I would like to try this method. One other item, if timing is the cause of the overtemp, is it too far advanced or retarded? TIA
