TODAY is a Great Day to visit our Store and order the parts you need for your truck!
36 degrees at idle is way to much. From your vac can all you need is 8-10 degrees this is my setup tried and true from Dave ray aka the ignition man. 375/ 41 center plates and weights from the distributor in an 84 suburban. They provide 21 degrees of mechanical plus 12 initial then 8 of vac. That is all you need. Nothing more or less.
Here's a chart with numbers for vacuum advance canisters, maybe this will help..http://www.lbfun.com/warehouse/tech_info/timing%20&%20vacuum%20advance/Vaacuum_Advance_Specs.pdf
