| The heavy dampner with the single line requires a timing marker that is incremental to show where you are setting the initial timing, you need to have that dampner indexed and lined/marked to show timing marks up to, say 42 degrees, in this way you are able to see what the timing advance is at any given rpm. I usually worry about total advance only and set my timing at 38 degrees which is nearly always correct. If you get any spark knock you can always back the timing down a degree or two to suit the fuel you are using. The heavy 427 dampner is designed to compensate for internal vibration due to harmonics that are inherent with reciprocating mass. If your engine is properly balanced you should not need the heavy flywheel or dampner. Basic Rule: light car = light flywheel, heavy car = heavy flywheel. A heavy flywheel will help to promote uncontrollable wheel spin in a really light car. I strongly suggest that you have the assembly balanced with the dampner and flywheel "0" balanced separately. This way you can do some changes at either end of the engine by simply having the new/replacement parts "0" balanced and not the entire assembly. Any decent machine shop should be able to handle the job competently. |
