Doh! Might have a bum lifter.
I've had a rather noisy rocker since last September. I just went and adjusted all of hte passenger side valves. It sounds 1000% better now, but I could swear that the rearmost rocker kept loosening up after tightening it. 
I'm got it all buttoned up and will see how it is after some more miles.

Its actually doing pretty good thanks. 
I haven't had the time to do nearly anything at all with it since the end of November when I started a new job. Between that and now looking to buy my first house it has been a pretty busy time for me.
It needs a fuel pump (over 4k gets lean, but not dangeriously) and the power steering has a slow leak, but otherwise it has (knock on wood) been reliable as hell for a long time now. I drive it at night and on weekends and it still melts the 315s pretty nicely.
Hopefully I can get a fuel pump in it soon and get it tuned fully. I've got a lot of vacation time to use up at work this year or I lose it. SloRvette did a real nice job even with the bum pump in it now, its much more responsive and stronger down low.
I've started replacing interior peices here and there too as the inside is getting pretty ratty for being what 21 years old this October and having 188k miles on it. I just need to get a new center conzole bezel and I'll have all of the interior parts that have silk screening on them replaced and looking new again.

Well i'm at a friends house that is 25 miles away. The car seems to have REALLY liked adjusting the valves, wow I wonder how messed up they were before. Its much responsive and seems to be pulling stronger. It could all be in my head, but who knows I'm happy. It does seem to have some clack left in it, but I'll do the driver's side next weekend and see if maybe its over on that side. I went 1/2 turn past 0 lash this time instead of 1/4 turn.

Yeah go it a bit tighter I guess.. Might help on the older lifters (If they are older)..
My '85 spun a bearing few months ago, and I just gave in and bought an LT1 instead.. She died after 121k miles. 75k miles of which were hard driven and raced by me teh past 11 years..
Man my lt1 feels slow compared to the low 12 high 11 sec '85 though..
Whatcha running in that car now? I remember you doing a teardown last I was reading looong time ago... lol

Scorp, I had a hydraulic lifter go "soft" on me too. Mine was disguising itself as a low rpm miss. I could push the plunger down BY HAND on the lifter after running the car while the others were rock hard. Hopefully it was just a lash thing for you.

Just give it a couple weeks, it'll either roast the clutch or the 4+3 will explode. Didnt you go with new lifters when you changed the motor?
Always something f'ing up with Scorp's luck

thats why I have two 4+3s sitting here on standby and ready to go! That way I'm assured the one in the car will never die since I spent money on backups. Yep, I bought new lifters when I redid the engine.
