    I just changed the headgaskets, put studs for the oil pan, and put a new oil pan gasket. Now I have a knocking sound from the lower end. I don't know what's going on with this thing. First everything was running real well, then I noticed oil pressure was reading around 65lbs from idle to 6000 rpm. Then came the knock. First it was a tick, so I re-adjusted the rocker arms (solid lifer cam). That wasn't it so I changed the oil filter and checked the oil bypass spring. They're fine. So now I'm pulling the engine again so I can inspect the crank. It never ends. Atleast I can count on the Suburban to get me home. By the way it's a Big Block 396 set up for the drags if you have any ideas to what the problem is.

    It's a wheelbase thing, you wouldn't understand.

    If your oil press doesnt change during the rpm band then something is wrong in the oiling system, like plugged oil galleys or some thing. At the track my Firebird has around 40 at idle, and going down the track it goes above 100 psi. On the street cruising it has around 45-50 psi.

    I have glitter in the bottom of my oil pan. It looks like the crank is comming out next.

    All of the main bearings are spun. Doesn't look like the crank is damaged too bad. I also pulled the #4 rod bearing, it's spun too.
