Yep, the old LE9 305 is toast...

Just got finished doing a compression test on my '86.. After seeing the blowby, I should have known what the results were gonna be... #1 was 60, #3 was 210 (I'm guessing carbon build up for that one), and the rest were between 150-180... Then I yanked the valve cover.... Looks like crumbled up charcoal inside... I think this old 305 has had it. Might be going to my local u-pull-it junkyard today and seeing about a 350. Ugh... At least I got her cheap!
