I have a 1984 c10 with a sbc 350 let it sit in backyard 1 year or so put a battery in started up with a ticking knocking also is back firing. Engine is shaking like a misfire
When rev back fires smoke comes
out carb oil level is fine noise is
coming from 8 cylinder area (sounds
like change in a dryer?) cylinder 8
lifters has a little play in them spark
plug on 8 didn't have any gap
It sounds like collapsed lifters on #8, you can try to adjust them just a little, but if they are collapsed, too much and the valves won't close. Check the distributor cap for carbon tracking, that can cause a pop back.
