ok guys, my 71 K-5 isnt runnin very good... 350/th350/205 It runs greaT when its cold it doesnt run worth a crap when it has been run on the highway for about 5 miles. New: distributor alternator battery carb intake its got a rebuilt HEI in it, and it works. no doubt about the distributor. the funny thing is though, ill set it on about 4-6 deg advanced, and it just runs crappy, so i end up advancing it so far, it doesnt register on my timing tab on the timing cover. THEN, when i finally get into town, after cruizing 5 miles on gravel, and 10 miles on highway, cruise about 60-65, ill pull into town, and as soon as i get slowed down enough to pull into town pump, itll die on me. it doesnt do this when its cold. anyone got any ideas?? thanks in advance.
