Ok, I've got everything on the go with the machinist. While that's going on, I've moved onto the next thing down the list; the torque converter. I've gone with the MoPar cam I mentioned above (lots of guys I talked to recommended it), the rear end I think I'll upgrade to 3.55's, so would I need...

Ok, I'll see what the machine shop guys want to do that, thanks! I've come across a MoPar purple shaft cam P4452782, 268/276 dur .429/.444 lift, idle to 5800. This is, or is a close match to, the stock 340 hp cam I'm told. Would that be a good choice?

Ok, I've got the cam down to two choices. Both are Summit cam kits. SUM-K6900- 278/288 dur, .421/.444 lift, 1500-5000 rpm. SUM-K6901- 276/288 dur, .441/.441 lift, 1800-5000 rpm. Both claim to be a good choice for a 9:1 build, and are the same price. Which one would be better for my build...

Ok, after some setbacks with house renos, I'm back at this. Got it degreased and checked. They're going to go 30 over, but otherwise the block is good. I've ordered a 9:1 master kit, should have it by the end of the month. The machinist told me he needs the pistons to do the final boring/honing...

I can't find any gauges to messure the bites myself, so it's off the the shop to be decreased and checked over. I guess I'll wait and see what they say. Thanks for the link, it's very informative!

Ok, found some time to get into this thing finally. Everything looks good, stock bores. All cylinders but one have nearly no wear (can feel a textural difference at top of bore, but no ridge), with one cylinder having enough of a ridge to catch my fingernail on. Came across a couple oddities...

Got it out and home. Looks good. Got the tranny (727) thrown in free! Should get it apart in the next few days.

Got a line on a '75 1/2 ton 360. I can use the pan and pick up from my junk one to do the swap. Bonus is that I've heard it run before buying it. Oil pressure is low (on the trucks gauge), but otherwise runs well. Should have it in the next few days.

If I just change out the pistons/rings/bearings, I'll just end up right back where I am. I have to fix the leaks or just change blocks. I've got a few people looking for another engine for me, and the "local" machine shop may have one in their bone yard.

I'm not sure I'd bother getting sleeves put in, as 360's are still relatively easy to find. I did email a few machine shops around, so I'll wait and see what they come back with. At the very least, I did get a good LD340 intake, the dual valve springs and perhaps and aftermarket cam. And most of...

Thanks everyone for all the great help! After lunch I went out to check things over, and one thing led to another, and I now have one of the offending pistons sitting on the bench. Unfortunately, that cylinder (#7) has a vertical crack down abouts halfway, 1 1/2" - 2" long, on the outer side of...

The chambers and valves on those cylinders look no different then the others. I'll take a closer look after lunch to be sure.

Sorry, that's the closest thing I could think of! I couldn't get a decent pic with my phone of all pistons, so I got a good one of one of the buggard ones.

My wife just asked if its possible something got into those cylinders that was hard enough to damage the aluminum piston, but not the steel walls/chambers/valves? I doubt it, but like I said, not much experience here. She's great at pointing out "out of the box"ideas, bless her soul.

The head gasket on the drivers side was good, the passenger side was so stuck it tore to pieces when I pulled the head off. I'll clean up the other pistons and see if I can get a clear pic of all of them (they're still in the block). Unless there was something bouncing about in there and it was...
