|Sitting here at another swim meet. Two.of my four kids made state which is where I'm at. One made it to Zone Age Group finals in Utah 3 weeks from now. Still unpacking in spare time...
Machine shop in CA did a great job with getting the cylinder bores round again using Diamond Hone. I'm not sure if this is an accurate way of saying it but it's like CNC honing.
Unfortunately, my pistons which have about 30 runs on them offer .0095" clearance. So new pistons or..
Consulted with Total Seal Rings and they HIGHLY suggested Line2Line coatings for the skirts. Google it. Basically it's an Abbradable Powder Coating which is applie to a near interference fit. You scuff the coating until you can push the piston through with both thumbs then assemble engine. Breaking in the engine wears the coating "self clearancing" and then the wear stops. Very good info on their web site so check it out.
Still not sold I contacted Diamond as that's the Pistons I have. Much to my surprise they immediately told me to call Line2Line. Or buy $1200 Pistons (gulp)!
Lastly, I was talking to a friend whom is an aircraft mechanic. He new all about APC as its used on turbine engines. He had training at General Dynamics and told me APC was the difference in one engine making 17,000 # of thrust and another making 22,000 # with APC. At that point I was completely sold.
Sent Pistons off this week. Looking at 10 day turnaround and $300 on 10 Pistons.
Once back I can start assembly.

|The front of the engine was leaking like crazy from the intake manifold. I removed the intake and timing cover and cleaned and repainted both and then reassembled same using a torker which really allows the engine to shine. The thing was ticking like a time bomb so I went under the valve covers and found one of the roller rocker pivots installed up side down so I fixed that and readjusted the roller rockers. You could see that one rocker arm was sitting way higher than the rest. Now quiet. The panel fit on the drivers door was way off and wasn't fixed before the pin stripe was painted on. I fixed the door fit then repainted the stripe. It's all about fit, finish, and function. That's what I do when I get a car. The charcoal canister was falling off from stripped screw holes. Fixed that. I AM very happy with the job he did in the interior. Beautifully wrapped steering wheel in matching leather. Seats beautifully done. Headliner real nice. Got to get rid of that carb and get something with an electric choke, though. Very nice vinyl top installation. Speedo way off. Still working on that. Engine is a beast. Trans is great (for an auto). Alternator or regulator was kaput when I got it, works fine now. The msd distributor was bottoming out in the oil pump gear groove and bouncing around like crazy while running so I went back to stock with a pertronix. The water pump was grinding into the back of the timing cover so much that you could barely turn it by hand so it took two gaskets to shim it out properly. Lots of HP left on the table there. Hood fit was way too high in the back when closed. It's all in the details......|

|Control Freak is about the only place making a setup like that. You can make your own for allot less.

| Bullet Cams has correct/proper cores for AMC engines. They also have Harold Brookshire's (Ultradyne) lobe profiles. I doubt there is a better cam designer than Harold, even when it comes to valve train longevity or power making potential. Tim at Bullet is a 30 year associate with Brookshire and the ideal person and place to acquire custom AMC cams. When I say custom I mean a camshaft tailored for you're particular needs, better than an off the shelf or other designers variety.

|Common problem. Comp Cams FINALLY got the issue addressed after years of complaints. On my CC's, shop just resorted to putting the cam in a lathe and turning down the back side which needs to be done or the lifter will interfere with the journal.
I use Redline Racing Cams. I know he has AMC cores which seems a rarity nowadays. These are custom; he designs and builds all in house. Call him a "boutique", but his stuff is fast and much better on the valve springs. Ask Adkins if you want a second opinion. Google it
