    I specialize in weird chit. I have seen oil senders leak bad down the back of the block. While you have it apart dont forget to check for cracks. Some years back it scrapped a intake because it had been over torqued by a prior owner.

    Thanks for the suggestion. There are no cracks that I could see. I went over and over it (and everything that was apart) while it was apart. Scraping all the old gasket material and such. Lightly flat filing to look for any aberrations. It looks like it was port matched at one time. I can can see the machine scribbled lines around the manifold ports. The lines are just to straight and consistent to be done by hand. I was a machinist for a decade or so, I know the difference.
    It's basically in pristine condition. I looked over every inch of it for anything out of the ordinary.
    Can you magnaflux aluminum? I was a machinist, not a metallurgist. :) If there are cracks that would be the only way I can see to find them. Not sure If I want to put the money into that, it would probably be cheaper to buy a new manifold.
    The thing is, it ran in the 12's when I bought it. I have not owned it that long, I wouldn't think it would do that with cracks.

    Take a straight edge and check the gasket surfaces on the intake and the heads.
    With out any gaskets in place set the intake on the engine it should fit square and not rock at all.

    Ok, what kind of rocker failure? Why did the rocker fail? I use rtv around the water passages on the intake. A thin coat. A dab on the outer corner bolts threads maybe. Can’t remember if they are wet bolts. I have to use engine hoist to remove the intake every time. I have a phenolic spacer that takes the place of the cork gaskets runs all the way front to back and it is close enough I can’t get a razor in to cut the rtv. A major PITA!

    Keep hot oil off the bottom of the intake. Plus no china wall oil leaks as a extra.

      Update: Since my last post was written, I tore some of the tendons from my left bicep and can not lift more than 10-12 lbs with it. This is why it's taken so long to get the engine out of the car. Finally, the stars aligned. One of my brothers, my youngest son and I finally pulled it two weeks ago. My son has been helping me out on Fridays. The trip from where he works to my house is a little over a half hour, the trip home is over an hour. I am most grateful for his help. He and I finally got the block stripped down last weekend.

      There are metal shaving everywhere. Not a lot, but everywhere. I took the bare block in to be hot tanked. I was referred to a engine re-builder by a friend of mine who is a long time drag racer that's been using them since the '70s. That said, I think I can trust him, especially after talking to the owner. My confidence grew as he told me (what I pretty much already surmised) that the damage was pretty minimal, mostly bearing replacement and such. Looks like I caught it before much damage was done.

      With all that's gone on and all that still needs to be done, I may just have them re-assemble the whole shootin' match. Or at least the short block.

        Where did the metal come from? Cam damage?

        There was a Mr. Gasket set of rocker arms on it. They had a ball and cup design for the push rods. The ball on the rocker arm broke off. It's about 3/16" in diameter so there wasn't metal to go around, but it got pulverized somewhere down the line and made it's way around the engine.

        I never did like the rocker arms. I had planned on swapping them out for something more substantial... Oh well. :)

        I never even knew that Mr Gasket made rocker arms, learn something every day.
        I would inspect your cam very well before reuse after suffering that type of failure.
