well , The owner (69flh) before me broke off a bolt to the pushrod block ! bandaided it back up and left it . I pulled it recently to see exacltly what it may need to fix ! this is what I found. They ground it down to what looks like to maybe use an easy out . They probly should have drilled it in the center .:rolleyes: Anyway , im not sure if its broke off in it or what . Best solution for a mechanicly inclinde broke mofo ? timesert ?

If you want to remove the bolt with minimum damage to the case, I think I'd find a machine shop with EDM (electrical discharge machining) machine.

Is the hole tapped into the cam chest or is it blind. If it's tapped all the way through, you might be able to get it out "fairly" easily.

If I were gonna try it myself, I'd use the lifter block for a jig. Bolt it on with the three good bolts, use a piece of tubing to sleeve the bad hole in the lifter block, center the drill bit and slowly drill the center of the broken bolt out until what remains in the cases is relatively thin. Since the hole is already off center and looks to be in the threads, once you get the center drilled out you should be able to crush the remains of the bolt inward and remove it.

1) If you have not done this before you will be way ahead to wait till you can afford a pro fix. It looks like it already has had enough amateur work. This can still be saved. But not likely by a amateur. The more you f it up the more it will cost in the end. 2) My .02 to remove it would be a fabbed 1/4x1x1 washer with a hole 1/2 the size of the bolt beveled out from that size then welded to the broken bolt and easyout with 3/32 Cronatron Eagle 3330. If you are a excellent welder that is the way I would go. If not #1 will be your best bet.

You can drill though to the cam chest.

^^^ If you can find a lifter block from a 77 and up would make this go much easier, they don't use the taper screws...
