My 1966 Falcon 200 block is just like yours. It's had 100 000 miles or 160000km's on it. It had been removed from the 1966 XR Falcon, and shoved into a 1968 XT Falcon, and given a really hard life. Split exhast header, split balancer seal, black as the ace of spades oil, and enough coke on the pistons and heads to fire a municpal power station, and the metallic fragments and pungent smell of sluge and leaded 97 octane in the sump.


Since the valve seats had been redone and the rocker gearwas adjustable, I've used it's reconditioned cylinder head on my 1981 Mustang. After 38500 miles or 62 000 km's, my 1981 3.3 block looked like this, even though the head gasket had been leaking for more 4000 km's since late 2010 when I got it.
So its nothing for those hard 60 thousand miles to really start ledging up the ridge above the ring lands.

Melling Cylinder Sleeves
140 Jacobson Drive
Maquoketa, IA 52060
Sleeving is a fine option for thin wall Fords due to a major issue of insufficient wall thickness to make 180 thou of wall thickness at the thrust faces for a normally aspirated 11:1 compression engine. All Windsor Ontario and especially Cleveland Ohio made engines were lacking in at birth wall thickness. Its about 120 thou if you have no core shift. If overbored 30 thou, and if there is core shift or rust, you can get down to 90 thou real quick. So as long as you use the recomended interfearance fit as required, you'll get good results.
In your case, fist option I'd use is CSL1106 on Page 4, 10/24, a 3.671" sleeve you can finish hone to 3.68", and its 5.5" tall, but requires a specific 3.8585" bore. or +178.5 thou. It takes out most of the cylinder wall in the mid span, but locks into the deck and bottoms just fine. Its wall thickness is 93.75 thou before honing, and 89.25 thou after. You have to realise that the wall thickness is supported, and the sleeve is strong and able to cope with a 3.68 bore but I wouldn't over bore it.
Also on Page 4 of 10/24, are other kits which will finish machine to over and kits CSL194 and
CSL1173 will do this.
As an example, from page 8 of 14/24 in the Melling PDF, there is sleeve kit CSL331F, a GM 4200 I-6 2002-07 Trailblazer kit which allows me to use a stock XR6 Turbo piston in a 1963 to 2012 Falcon I6 engine block. I can use 3.632" pistons, and still have enough wall to go to 3.68".
