84 D150 regular cab 2wd.headers and ALL pol equip removed The pick up ran great but I thought maybe it could run greater. The timing was right on spec (12 degrees btdc). No computer, it has centrifigul advance. I bumped the timing 4 degrees so now at 16 btdc. Holy Toledo does it squeel the tire now. No pinging (an advantage of low comp 84 318), it runs cool. My total advance (vac plugged) is 28 degrees (2500 rpm or so). Now I pulled distrib to clean it up, lube it up and I threw the heavy spring away. I'll set the timing just as when I took it out
