Broken Lifters?

[firebane]

I'm not sure what to really call this but I am in the process of swapping intakes to rid myself of the heavy ass cast iron manifold and finally got it off then I noticed this.

I have 3 circles that I am particularly looking at.

2 of the red circles shows the lifters unseated from their normal position than all the others. Is this normal? The other thing I found was a u shaped clip which looks like it may have come from a lifter.

The other thing of concern is the one push rod that is absolutely spotless that I have also circled in red.

Now before I really go and drop a bunch of money on this motor its a tired old 305 which I recently disocvered and thought was a 350. I can probably find a fairly cheap short block 350 for $200-300 and do a fairly quick swap with everything I already have.

Anyone have advice on what may have caused this issues?

Lifters move up and down, that's normal. That one pushrod has likely been replaced. Got a picture of the clip? Are any lifters missing a clip? Did it run fine?

Well I feel better knowings its normal. The truck just felt sluggish and ran like a dog but I have no idea on the mileage of the engine.

Apparently the PO decided to use rtv sealant on the valve coveres and I didn't find any rtv sealant on the front and rear edges of the intake.

Regarding the clip its the middle one shown here:

Yeah, that looks like a lifter clip. If none are missing, I'd suspect there was a failed lifter/pushrod/rocker that was repaired at some point, and the clip was left behind.

I haven't gotten a chance to look that far as it was getting dark. I'll look tomorrow when I'm out working on it again.

Hopefully its leftovers.
