It looks like part of the block is missing near the intermediate shaft.
Hard to tell from the picture, but I agree.It looks like part of the block is missing near the intermediate shaft.
The lifters rotate when the engine is running, and the push rods can too. So your pushrods are rubbing on the heads. Hence the rotational marks. Run (idle) the engine with the valve covers off, and use a short piece of hose held up to your ear. Hold the other end near each rocker arm pushrod, and find the source of the noise. It will be quite obvious, as the sound will come thru loud and clear thru the hose. I use a short piece of garden hose. Fuel line works too. You will need to grind or file away some metal around the push rod holes to fix it.Thanks for all the input guys. I’m gonna year back into it hopefully this evening. If I can clear my workload. I’ll try and get a good measurement on lifts first. My lifters aren’t squishy at all (which may could be a problem??) figures they were just pumped up. I’ll cut open filter as well and check all my header bolts for tightness.
On those pushrods I’m pretty certain the rub marks are from my run. If you can see the pic in first post notice the rotational marks instead of vertical marking, what would this indicate?
440 source has a permanent valley pan, it stays on there. Then you use the paper type intake gaskets for the manifold. Only problem here is, the valley cover edge sits below the cyl head. So you can remove the intake, but to access the lifters you have to pull at least 1 head! There may be another type I don't know about. I think Moroso, Mancini, Mopar, and others may have them too. Also, stage VI heads use the stock valley pan with the manifold port area cut off. Then a spacer goes over that, and you use the paper gaskets. Then the spacer can be removed, and the valley cover.It's going back together with some mopar adjustables so I'll have to measure for new rods and order those, then get everything back together. Sort of a relief to see everything is fine thus far though.
Anyone got suggestions on a better valley type?
For sure. Easy way to tell if cam and lifter goodYou need to reassemble it. Get a dial indicator and compare the amount of lift at the spring retainer from one to another. That will tell you if the cam is shot.
Yes I would slide every lifter out of its hole. Just to make sure each lifter will come out easily.Since you’re already into it this far, before putting the intake back on...... i’d suggest reassembling the rocker gear first, and then bumping the motor over with the starter and checking the lifter rotation.

Hughes has several, that don't require head removal. Some have a clear plastic cover. You can see the cam when it's running. Check out the AR 300A. Might work for you.It's going back together with some mopar adjustables so I'll have to measure for new rods and order those, then get everything back together.

Good idea. I once had a 451 in a Belvedere, and it Started knocking real loud. I was getting ready to pull the motor, but checked the T/C bolts first. Sure enough, 2 had backed out a little, and were hitting the Block! Easy fix, I put em back in with Loc Tite. That's why I suggest using a piece of hose to isolate the knocking sound first.just a thought, have you checked torque converter bolts? engine accessories?

I was messing around the other day after I got my new exhaust welded up and put back in. Cranked her up and noticed a hefty tick.
I know you've already torn into the motor, but from the clip you posted, it could be an exhaust leak. The fact that you started noticing it right after welding up a new system may not just be a coincidence...
Max, it's hydraulic.Hydraulic or mechanical cam?
