59L block sleeving
I have 59L block bored 3.312, 3&5/16". The machine shop pressured tested it before they started some seat replacement work and found a leak in the #4 cylinder wall near the exhaust port. What is the thinnest sleeve you can use the to bore out that cylinder and sleeve it back to 3.312. Thank you Fordbarners.

Re: 59L block sleeving
There have been flat head V8 cylinders bored through to the water jackets to get big sleeves installed. They usually leave a ledge around the bottom of the cylinder to locate & stabilize the bottom of the sleeve and good old JB Weld epoxy to help keep the cylinder and deck surfaces stable up top. One outfit did this to all eight cylinders in a 21 stud engine in order to get it out to 3 3/16" and use a 4-inch stroke crank so they could run the Great American Race in a 1935 or 36 Ford coupe (I don't remember which). It made it all the way without problems and I think it's still going. 255 CID is pretty big for an ole 221 engine. The 24 stud engines will go farther but the rest of the deck & valve pockets should be in good condition to start with.

Re: 59L block sleeving
I would think the mechine should be able to help you select a sleeve. If there is any question about cylinder wall thickness have it sonic checked.

Re: 59L block sleeving
I bought a '36 sedan that had a ton of parts with it, including a '36LB block that had the cylinder walls bored out and sleeved with 3 3/16 sleeves. It ran hot and puked water out one header when I ran it in the frame to break it in. Thought I had it sealed up and completed the car, only to have it get hot just a couple miles into the first test ride. Tore it down and one sleeve had a 3 inch vertical crack. Bad sleeve??? Who knows. In my opinion a good LB block was wrecked for no good reason. Rod

Re: 59L block sleeving
I've run these blocks bored to 3 7/16 in a stock car. Also in a 40 Ford coupe with all the rest of the goodies, and that was 20 years ago and it;s still running.
So sleeving should be OK |

Re: 59L block sleeving
I have had some Factory Ford re-builts, (Somerville MA plant), that have very thin wall sleeves.
